Imagine this scenario. You walk into the conference room, place your phone on the table and take a seat. Mysteriously, the phone wakes up and an invisible finger unlocks it and installs malware. Call Ghostbusters? Better yet, call the research team whose “invisible finger” presentation wowed attendees at the Black Hat conference in Las Vegas.

This team, called “Security in Silicon Lab”, brings together professors, doctoral students and other academics from the University of Florida and the University of New Hampshire, all of whom have extensive expertise in electronic hardware and in mathematics and physical. that make modern technology possible.

Haoqi Shan, a UF PhD candidate, presented the Black Hat presentation of the group’s findings and started with the short version. “This is a remote precise touch injection attack against capacitive touchscreens using an IEMI (intentional electromagnetic interference) signal,” he said. “Our attack has an effective range of three to four centimeters. We can induce a short press, a long press or a sweep in any direction.

Shan called the move “a relatively new type of attack, even for professional researchers, [though] once you get the knowledge here you should be able to replicate what we are doing now. Maybe you’ll come up with a stronger or much cooler attack.

This is a big maybe, as further research would obviously require high-powered equipment as well as extensive knowledge and expertise.

Shan launched into a detailed description of how a capacitive touchscreen works to control your tables and phones. Skipping the physics involved, it just goes like this. An electronic system transforms capacitance events that occur when you touch the screen into a voltage that can be measured. The team’s attack works by using electromagnetic fields to manipulate this voltage.

“In theory it might work, but we don’t know at this point,” Shan said. “We set up an environment that allows us to generate a field using a copper plate so that we can learn to control the touch event.”

The team went through many iterations, learning the best field strength and frequency to use. “We need our electronic field to be really focused,” Shan said. “We used two methods. The spring-loaded copper needle is more accurate, but the copper plate gives a stronger signal.

From theory to practice

Either way, a robotic arm is used to precisely position the antenna.

“For a real attack, you can’t use a robotic arm,” Shan said. “We used a sparse antenna array to determine the location of the phone and another array to perform the test. Our attack works on iPad, OnePlus, Google Pixel, Nexus, and Surface. It’s more universal. It acts like if your finger did the job. We can even generate an omnidirectional swipe on iPad and Surface. We could totally use it to open a gesture-based lock.

The team designed a complete attack vector. An antenna array under the table picks up the precise location of the phone or tablet. Another antenna array sends signals that trigger touch events. And by measuring emissions from the touchscreen, the attack system can verify that each touch is successful. A brief video shows the final attack in action.

What attacks are possible? What Defenses?

As for a real attack scenario, “we managed to install a malicious app on Android,” Shan said. “We could send money by tap and hold on PayPal. We did an attack on Siri that works nine times out of 10.” He noted that other attacks have proven less consistently effective, in one case because the Yes and No buttons on Android are very close together. ‘other.

Touchscreen manufacturers could thwart this attack by including simple pressure or force sensing. Your finger exerts a little pressure; the invisible finger attack does not. “As far as consumers are concerned,” Shan said, “you can use a Faraday bag, but that renders your phone inoperable. We found good protection tests in a case with a cover and Faraday fabric.

The group’s website also notes that laying your phone down with the screen up is enough to protect it from the attack in progress.

“We are still actively working on this offense to make it more perfect,” Shan concluded. He also noted that the group is actively recruiting PhD students working in cybersecurity. Is that you? You can contact the group on their Invisible Finger website, which also features FAQs and videos about the project, as well as the scientific paper this presentation is based on.

Concerns about electromagnetic radiation emitted by Apple AirPods have been growing recently, but just how dangerous is it in real life?

Concerns about electromagnetic radiation emitted by Apple AirPods have increased recently, but how dangerous is it in real life? Electromagnetic radiation, which includes radio waves, microwaves, X-rays, and gamma rays, is well known to wreak havoc on living tissue, causing cancer and other deadly diseases. Sunlight also radiates electromagnetic energy, but visible light forms only a tiny part of the electromagnetic spectrum and is generally considered harmless.

Apple announced its first generation AirPods in 2016 before launching the second and third generation models in 2019 and 2021, respectively. Meanwhile, Apple also launched the more feature-rich AirPods Pro headphones in 2019 and the AirPods Max over-ear headphones in 2020, which are Apple’s most popular accessories. The company is expected to launch the second-generation AirPods Pro this fall alongside the iPhone 14.

Related: Which AirPods have active noise cancellation?

Concerns about radiation levels in wireless electronic gadgets are not new, but a Reuters The fact-check article has now debunked recent social media chatter that Apple’s AirPods may be responsible for cancer. According to scientific research and studies cited in the report, “there is no established proof” that the radio frequencies emitted by Apple AirPods are harmful to the human body. On the contrary, the evidence suggests that the levels of radio frequency emitted by the devices are well within the limits prescribed by the United States Federal Communications Commission (FCC) and, as such, are safe for use by the general public.

Apple AirPods radiation levels

The report explains that the FCC requires all electronic devices (including cell phones and Bluetooth headphones) sold in the United States to maintain their specific absorption rate (SAR) at less than 1.6 watts per kilogram. According to Apple’s public filings with the FCC, the AirPods recorded SAR levels of 0.071 and 0.095 for the two individual buds, which is less than half of the maximum level prescribed by experts. As for the AirPods Pro, they have SAR measurements of 0.097 and 0.072 watts per kilogram head, which means they also comply with FCC regulations.

It should be noted that the FCC’s SAR limits are stricter than those of the International Commission on Non-Ionizing Radiation Protection (ICNIRP), which recommends that SAR levels be less than two watts per kilogram. According to the organization, as long as the gadgets meet prescribed radiation levels, they should have no adverse health effects on users. ICNIRP also stated Reuters that the latest research also shows “there is no scientific evidence that EMFs (electrical, magnetic and electromagnetic frequencies) cause cancer.”

Two other notorious public health organizations that have backed this claim are the World Health Organization (WHO) and Public Health England. The elder said Reuters that there is “no proven evidence” than Apple’s low-level electromagnetic fields AirPods would cause cancer, whereas the latter said that there was “no convincing evidence” that exposure to electromagnetic fields within the limits of the levels recommended by the ICNRP will have adverse health effects.

• The war in Ukraine, like all wars, has seen innovation and the rise of new weapon systems.
• The five-month-long war has elevated drones, rockets and electronic warfare to new masters of the battlefield.
• Weapons like the HIMARS rocket systems were primed and ready for conflict. Yet there is a gaping hole that new weapons can fill.

The Russian invasion of Ukraine in February 2022 demolished the expectations of military experts around the world. Some basic elements of warfare, such as tanks, fighter jets and howitzers, proved surprisingly vulnerable during the conflict, while rocket artillery, drones and anti-tank weapons exceeded their weight. Others, like lasers that could protect cities and weapons that focus on radio signals, are urgently needed but have yet to be developed.

War supercharges innovation; the life-and-death struggle between nations drives participants to adopt new technologies to enable new tactics and strategies. Battlefield experience quickly sorts out what works and what doesn’t – the former being quickly embraced and the latter just as eagerly abandoned. The invasion of Ukraine is no exception. Here are five weapons you’ll be seeing a lot more of in the near future.

defensive lasers

The American army

Russia’s war has involved both ‘dumb’ unguided weapons and ‘smart’ precision guided weapons, in the form of mortars, howitzers, multiple rocket launchers and attack cruise missiles. earthly. Russia spends up to 60,000 artillery shells and rockets per day, raining destruction on military and civilian targets. Moscow used these weapons for military purposes and civil targets – and the latter is clearly a war crime under international law.

Historically, there has been little defense against artillery and aerial bombs other than the destruction of the launchers associated with them. In recent years, the WE and countries, such as Israel, focused on lasers as a means of protecting armies in the field. A laser, powered by a diesel generator, has virtually unlimited ammo and can quickly target and destroy multiple threats in seconds. Russia’s vicious attacks on cities and other civilian targets have shown that laser defenses have their place in protecting non-military targets as well.

Anti-Radiation Weapons

US Navy

A major advantage Russia had over Ukraine at the start of the war was its advantage in electronic warfare. Russia has long prioritized the ability to broadcast powerful jamming signals capable of interfering with an adversary’s radar, GPS and battlefield communications. A recent report credited Russian electronic warfare capabilities and their ability to jam Ukrainian military communications are weakening the country’s defenses. Russia also broadcasts its own radio signals, which include air defense radars, wireless drone control signals and wireless military communications, linking the entire Russian military campaign randomly.

Ukraine would benefit from the ability to detect and attack Russian systems emitting powerful electromagnetic signals. An anti-radiation missile (ARM) capable of targeting and then destroying enemy radars, communication trucks, jamming vehicles and other transmitters would be very useful, not only to allow Ukrainian forces to better coordinate, but also to make deaf and blind Russian forces. . Unfortunately, although this ability is available at higher levels, most notably in US Navy launched aircraft AARGM anti-radiation missile, it is clearly lacking at ground level. Expect to see weapons deployed by armies within five years.

Guided Rocket Artillery

The latest star in this conflict is the American-provided High Mobility Rocket Artillery System (HIMARS). HIMARS consists of a reloadable rocket launch system mounted on a medium truck chassis. HIMARS can quickly move to a firing position, release six precision guides GMLRS rockets with a range of 43 miles or more, and retreat to avoid enemy counter-battery fire. HIMARS far exceeds conventional tube artillery, including cannon artillery like the 2S19 Msta self-propelled howitzer.

Ukraine currently uses HIMARS for interdiction missiles, hitting high-value Russian targets behind enemy lines to deprive frontline troops of artillery supplies and support. At the end of July, Ukrainian HIMARS systems destroyed 50 Russian ammunition depots.

Traditional cannon artillery simply does not have the range to “outrun” enemy artillery, and currently there are no weapons, at least on the Russian side, that can shoot down GMLRS rockets. Few countries outside of NATO have precision-guided rockets, but the success of HIMARS + GMLRS means most countries will probably have them in a decade or less.

Small Battlefield Drones

The Russian-Ukrainian war is not the first war to use quadcopter drones for surveillance missions, but it will be the most famous war for them. The Ukrainian army, in particular, used small quadcopter dronesoften designed for the civilian market, to give ground troops the ability to check their surroundings and target enemy forces while minimizing risk. These drones allow units as small as platoon level (30-40 soldiers) to eliminate the element of surprise for any enemy force, especially those using armored vehicles.

A small, unobtrusive drone with modern digital optics and a secure data link can give even the smallest combat unit an unobstructed view of the battlefield and the ability to look a mile or more behind enemy lines . Ukraine’s experience with small battlefield drones means NATO armies, the People’s Liberation Army of China, the Japanese Ground Self-Defense Force and the South Korean military will all adopt them from here. 2030.

satellite internet

According to New York TimesUkrainian helicopters carrying out dangerous missions in the city of Mariupol brought a supply of anti-tank weapons and a crucial non-weapon: a SpaceX Starlink satellite internet receiver. The receiver proved a lifeline for military and civilian forces trapped in the besieged Azovstal steelworks. The receiver, connected directly to the satellites above, allowed users to bypass war-damaged cell phone service and landline internet. Boosting civilian morale, it allowed the Ukrainian government to inform the world of the siege and act as a backup for Ukrainian military communications.

The US military faces a growing Internet bandwidth problem, largely due to its routing of as much secure military traffic as possible through as few satellites as possible. This makes the system vulnerable in wartime to even a few anti-satellite weapons. SpaceX, with its thousands of relay satellites, has created a less secure, but more resilient network. While Starlink may not be secure enough to handle sensitive military communications, it will almost certainly inspire a military-grade version down the road. This version will combine the security of existing military satellites with the coverage of Starlink, allowing it to survive the loss of dozens of satellites to enemy action.

Has the science behind smashing opera singers led to a century-old cure for cancer?

A viral image on Facebook suggests so, writing that an American scientist named Royal Raymond Rife “knew that everything vibrates at its own natural frequency”. Believing that if he “could discover the frequencies of pathogenic organisms, he could destroy them with the same vibrational frequency”. The image goes on to claim that the device he invented – now known as the Rife machine – can cure cancer.

But, the device is not approved by the Food and Drug Administration, and the American Cancer Society, Cancer Research UK, Medical News Today and WebMD have all reported that there is no reliable scientific evidence that the device works as a cure for cancer.

The post was flagged as part of Facebook’s efforts to combat fake news and misinformation on its News Feed. (Learn more about our partnership with Facebook.)

(Screenshot from Facebook)

Rife machines, used in alternative medicine clinics today, emit low-energy electromagnetic waves, similar to radio waves. The waves are delivered to the body via electric pads on the hands and feet or via portable plasma tubes. WebMD reports that these devices are generally safe.

According to a 1994 report by the American Cancer Society titled “Questionable Methods of Cancer Management,” Rife based his device on an unsubstantiated medical theory called “radionics.”

The theory was promoted by Dr. Albert Abrams who practiced in the late 1800s and early 1900s. He believed he could build a device that would detect radio frequencies of disease and heal people by emitting ” disease-destroying vibrations” at the same frequencies. He died in 1924, unable to recover from pneumonia or cancer from one of his wives.

But Rife, who believed that cancer was caused by bacteria, created such a device based on the principles of radionics, naming it the Rife Frequency Generator. Rife also invented several microscopes and believed he “could visualize the auras of living microbes…(and), use the color of the auras to calculate the electromagnetic frequency of those microbes.”

But the science behind it was flawed. “Although sound waves can produce vibrations that will break glass, radio waves cannot destroy bacteria due to their low energy level,” the ACS wrote in the 1994 report.

The device regained popularity in the late 1980s and 1990s with the publication of a book called “The Cancer Cure that Worked, 50 Years of Suppression”. Although Rife clinics still exist, several practitioners have been convicted of fraud and prosecuted for treating cancer patients with or selling devices similar to Rife machines.

Recent research has begun to explore the effect of radio frequencies on cancer cells, but the research is in its early stages and uses different frequencies than those used by the Rife machine.

“There is evidence that the application of certain radio frequencies can have favorable results. However, the human body, or even a cancer cell, is an extremely complicated system,” said Ivan Brezovich, one of the researchers at the study and professor emeritus in the Department of Radiation Oncology at the University of Alabama.

“There are countless variables that need to be fully explored, such as what frequency or frequencies to use, when should they be applied, at what intensity, to what parts of the body, for what types of cancer, etc.”

Brezovich believes that more research needs to be done and believes that “patients should not forego a proven treatment method until a new modality has been verified in a scientific setting.”

A miracle cure for cancer would be wonderful, but there is currently no evidence that Rife machines are that miracle.

We rate this claim as false.

Tonight the moon is new – no moonlight to interfere with starlight.

Once the sky turns completely dark (10:00 PM PDT), get out and look up. Almost above our heads, a faint band of light illuminates the sky: the Milky Way.

A flock of birds…a herd of cows…a galaxy of stars.

Our sun is one of one hundred, perhaps two hundred billion stars residing in our galaxy, named after its glow: the Milky Way galaxy.

The Milky Way galaxy is a spinning pinwheel of stars. The glow we see tonight comes from regions closer to the center, where the stars are closer together. The Milky Way shines brightest in Sagittarius, which will rise later tonight (earlier, in the coming months). The Sagittarius glow marks the very center of our galaxy.

The Big Dipper is high in the sky tonight. Think of the Dipper’s bowl as a picture frame; in the middle of the 20th century – before we had space telescopes – astronomers had found, just inside this frame, tens of thousands of galaxies. Scattered in all directions, countless billions of galaxies drift across the universe.

Galaxies come in many shapes and sizes. We can’t see our own Milky Way galaxy from the outside, but astronomers have mapped our galaxy from the inside. The maps reveal that our galaxy is of a type which is – without any trace of chauvinism – the most beautiful: the Milky Way is a spiral galaxy.

Some fundamental questions: How are galaxies formed? What creates those beautiful spiral arms?

Two objects, visible to the naked eye, provide clues.

The Big Dipper, high in the sky on these nights, is a sign pointing to important parts of the sky.

In the Dipper Bowl, the last two stars are, literally, “the pointers” – they point to Polaris, the North Star (not a very bright star; it just happens to sit, 24 hours a day). 24, 7 days a week, above the North Pole of the Earth. ).

The handle of the Dipper also points, but not straight – the handle forms an arc. Follow the arc around, and the eye comes to (much brighter) Arcturus: “Follow the arc to Arcturus.”

Our galaxy is a huge windmill of stars. All the stars in our neighborhood move in roughly the same direction… but for Arcturus. If the stars around us were a flat target, Arcturus would be an arrow, flying – fast – through that target.

This fall, another object will be visible to the naked eye…an object that is not from our galaxy…at least, not yet. A faint ball of fur, Andromeda is another galaxy, outside of ours… larger than ours… and heading, on a collision course, towards ours. In a few billion years, the Andromeda galaxy and the Milky Way will collide. Like projectiles in a snowball fight, the stars are unlikely to collide…but they will feel each other’s gravity…pull into each other…eventually causing Andromeda and the Milky Way.

Arcturus was probably once a member of another galaxy… the one that collided and merged with the Milky Way. The strange movement of the star would then be a vestige of this collision.

A hypothesis (an educated guess): galaxies form from much smaller clusters of stars, colliding and merging. Such mergers were once common.

To really see how galaxies formed, we have to go back in time…far back in time…we need a time machine.

Looking back

About two thousand five hundred years ago, on the eve of battle, the Greek army was outnumbered… but clever strategy led the Greeks to victory.

A courier was dispatched to bring the news to the distant capital. Running non-stop, the courier brought the news to Athens in just two days…whereupon he died of the effort.

Today’s foot races commemorate the long run of this courier, heralding the Battle of Marathon.

The courier’s run was impressive…even though, by the time he arrived in Athens, the news was two days old. Today, we receive news instantly, transmitted by radio waves. Like all electromagnetic waves (visible light, X-rays, infrared, ultraviolet and gamma radiation), radio waves propagate at the speed of light… which can circle the Earth seven times in one second.

Electromagnetic radiation travels fast, but the distances between galaxies are large. The light that we will see this fall left Andromeda two and a half million years ago…we will see Andromeda as it was two and a half million years ago.

The information we get from galaxies is old news… but that’s fine, if we want to look back in time. The farther we look, the further back we look in time.

Of course, as things get further away, they also get darker, which is why we need telescopes – buckets of light – to collect and focus light from distant parts of the universe. Looking out… looking back… telescopes are time machines.

Large telescopes collect and concentrate light with mirrors. The larger the mirror, the more light the bezel collects… and the further back in time it can go.

The Hubble Space Telescope had a mirror eight feet in diameter. Our newest space telescope – the James Webb Space Telescope – carries a mirror twenty-one feet in diameter. Just beginning its mission, JWST will travel far back in time…to hopefully show us how galaxies began to form.

In the sky

Friday evening, rising in the northwest at 10:01 p.m., the International Space Station will pass directly overhead a few minutes later.

Radio astronomy is the study of invisible radiated energy in the electromagnetic spectrum under visible light. Society Fellow Kerry Smith will introduce the radio astronomy portion of the event and provide attendees with a glimpse into the future of the Society’s radio astronomy efforts.

Attendees will also be able to view the sun through the company’s solar telescope, as well as view it remotely on a television screen that will be hooked up to a telescope.

The company will also offer a program on How to Buy an Astronomical Telescope. Society members will offer information and advice on how to purchase your first optical astronomical telescope. This presentation will begin at 1 p.m.

If you have a telescope and don’t know how to use it, bring it to the observatory and the society members can help you.

If clear, all activities will proceed as planned. If it is completely cloudy or raining, the indoor astronomical presentation will take place as scheduled.

A Chinese-made unmanned helicopter made a successful test flight after taking off from a ship in the port city of Qingdao, state broadcaster CCTV reported.

The test flight of the AR-500BJ, developed by the helicopter research arm of the state-owned Aviation Industry Corporation of China, paves the way for small autonomous helicopters to operate on the high seas, CCTV said on Friday. .

While state media and Avic hailed the flight as a significant step forward, the aviation giant didn’t give details on its technology and a military analyst said these autonomous helicopters have few applications. defense.

“In this demonstration and operation at sea, the AR-500BJ smoothly performed flight elements such as take-off and surface landing, marking a new and important breakthrough in the development of this type of helicopter without pilot,” Avic said in a statement on WeChat. .

The helicopter weighs 500 kg (1,102 lb), according to CCTV. The helicopter was equipped with a Chinese-made heavy-fuel engine and flight control, structural, electrical and fuel combustion systems modified to fit the small parking area of ​​a ship.

The helicopter was also designed to withstand “complex electromagnetic environments” – a military situation where electromagnetic signals interfere with the ability to monitor the battlefield.

But it’s unclear what military duties, if any, he might perform.

“The military use of autonomous helicopters is unclear,” said Zhou Chenming, a researcher at the Yuan Wang military science and technology think tank in Beijing. “There is no clear military use for them, even on a global scale.”

He said fixed-wing drones have greater range and speed, while being cheaper to operate.

The US Navy has used RQ-8 autonomous helicopters for intelligence gathering, surveillance and reconnaissance, but it relies more on smaller fixed-wing drones such as the ScanEagle designed by Insitu, a Boeing subsidiary.

Zhou also warned that the complex structure of the AR-500BJ would make repairs difficult.

Avic’s helicopter arm said it took over the project in 2017 to test the AR-500’s ability to adapt to operation on ships and on the ground, as part of a key national research project. and development.

Friday’s test spelled the end of the helicopter arm’s involvement, he said.

The AR-500BJ project officially started in 2018, and the helicopter made its first flight from a ground base two years later.

China is actively developing drones for civilian and military use, to improve logistics and deployment flexibility.

Chinese-made military drones have also been popular with countries like Algeria and Egypt, as they are less expensive than American and European drones.

The reflection process was studied using the three-dimensional (3D) particle-in-the-cell (PIC) code EPOCH³⁵. The famous Laguerre-Gaussian (LG₀₁) mode is used as a typical vortex beam, and it can be expressed as^36.37

when it spreads in X direction. Here, (r=sqrt{{y}^{2}+{z}^{2}}); (varphi =mathrm{arctan}(z/y)); ({k}_{0}=2pi /{lambda}_{0}) is the wave number; and the wavelength of the incident beam is ({lambda }_{0}=0.8 mathrm{mu m}). In addition, (wleft(xright)={w}_{0}sqrt{{(x}^{2}+{x}_{r}^{2})/{x}_{r} ^{2}}),(mathrm{where } {w}_{0}=6.25{lambda }_{0}) is the beam waist radius and ({x}_{r}) is the Rayleigh length. The longitudinal profile was composed of ({mathrm{sin}}^{2}(pi t/2tau )) and (tau = 26.7mathrm{ fs}). The dimensionless amplitude ({a}_{0}=e{E}_{0}/{m}_{e}c{omega }_{0}=1)where (e), ({me}), ({omega }_{0}), ({E}_{0})and (vs) are respectively the charge of the electron, the mass of the electron, the laser frequency, the maximum amplitude of the laser field and the speed of light in vacuum. In our PIC simulation, a linearly polarized LG₀₁ incident beam obliquely on the flying mirror with ({theta }_{in}=pi /6) (compared to the X axis), as shown in Fig. 1. Initially, the LG laser was injected from (x=-5{lambda}_{0})and the flying mirror was standing and occupying the domain in (13.75{lambda}_{0})X (15{lambda}_{0}), (-18.75{lambda}_{0})there (18.75{lambda}_{0}), (-10{lambda}_{0})z (10{lambda}_{0}). The electron density of the mirror was 20 ({NC}) to ensure that the laser pulse has been completely reflected^17.38here,({NC}) is the critical density. The flying mirror was moving in the –Xsteering at a speed of(v=0.5mathrm{c}). Here we note that the speed of the flying mirror was set to 0.5c instead of a more relativistic speed to save computational resources, i.e. to achieve fast separation of the laser from the target and avoid the influence of digital heating. The simulation box was a (25{lambda}_{0})× (50{lambda}_{0}) × (25{lambda}_{0}) cuboid corresponding to a window of 400 × 800 × 400 cells in the X× there × zdirection, and each cell had 10 macroparticles.

The simulation configurations of the incident and reflected electric fields are shown respectively in Figures 2a,b. Compared to the field before reflection, the distribution of the reflected field changed significantly, including the profile and the direction of propagation. In Fig. 2b, the arrow indicates the direction of the LM of the reflected beam, defined according to the direction of the LM, which must be perpendicular to that of the electromagnetic field. The wavelength of the reflected beam was lower than that of the incident beam and the angle of reflection was lower than the angle of incidence due to the relativistic effect. As shown in Figure 2c, the laser was tightly focused and the longitudinal component of the electromagnetic field could not be ignored; So the k -the profile of the spatial spectrum of the reflected field has undergone a spectral broadening. According to the coordinates of the center of gravity of the laser, the wavelength and the emission angle of the reflected beam were ({lambda }_{1}=0.283 mathrm{mu m}) and ({theta}_{re}=0.174) rad, respectively.

(a) Distribution of the incident electric field ({E}_{y}) in the X – there plane. The black box shows the electric field selected to calculate the OAM. (b) Distribution of the reflected electric field ({E}_{y}^{mathrm{^{prime}}}). The arrow indicates the direction of the LM (the direction of propagation of the reflected beam). The length is normalized to ({lambda}_{0}.) The field is normalized to ({m}_{e}{omega }_{0}c/e(4times 1{0}^{12}mathrm{V}/mathrm{m for }{lambda }_{ 0}=0.8mathrm{ mu m})). (vs) The k – profile of the spatial spectrum of the reflected beam. ({{varvec{k}}}_{{varvec{x}}}^{mathrm{^{prime}}}mathrm{ and }{{varvec{k}}}_{{ varvec{y}}}^{mathrm{^{prime}}}) are the components of the wave vector in the X and there direction, respectively, normalized to ({k}_{0}). The intensity is normalized to the maximum intensity.

Otherwise, ({lambda}_{1}) and ({theta}_{re}) can be derived from Doppler shift formulas. Using the Lorentz transformation, in the frame of the flying mirror, the angle of incidence ({mathrm{tan}theta }_{mathrm{in}}^{^{prime}}=mathrm{sin}{theta }_{mathrm{in}}/(gamma mathrm{cos}{theta }_{mathrm{in}}+gamma beta )) and the wavelength of the incident beam ({lambda }_{0}^{^{prime}}={lambda }_{0}(1/left(gamma +gamma beta mathrm{cos}{theta }_ {mathrm{in}}right))) with the relativistic factor (gamma=1/sqrt{1-{beta }^{2}}), (beta =v/c). In the same frame, the angle of reflection is equal to the angle of incidence. By inverse Lorentz transformation, in the laboratory reference frame, the reflection angle (mathrm{tan}{theta }_{mathrm{re}}={mathrm{sin}theta }_{mathrm{in}}^{^{prime)}/(gamma { mathrm{cos}theta }_{mathrm{in}}^{^{prime}}+gamma beta ))and the wavelength of the reflected beam ({lambda }_{1}={lambda }_{0}^{^{prime}}(1/left(gamma +gamma beta {mathrm{cos}theta }_ {mathrm{in}}^{^{prime}}right))). For ({theta }_{in}=pi /6) and (beta=0.5, {theta}_{text{re}}=0.176) Rad and ({lambda}_{1}=0.281 {upmu}{text{m}}) were obtained, which are in good agreement with the simulation results.

Considering the angle of reflection, the changes in the beam profile can be well explained. As shown in Fig. 3, the red quadrilateral (ABCD) was chosen in Fig. 2a. The incident beam was reflected along (overrightarrow{{mathrm{AA}}_{1}}) (the direction of the LM), and the angle between the LM and the electric field profile was defined as (varphi)where (mathrm{sin}varphi /mathrm{sin}(varphi +{theta }_{in}+{theta }_{re})=beta mathrm{cos}{theta }_ {in}/mathrm{cos}{theta}_{re}). When the AB aircraft began to interact with the flying mirror, the target was at X₁ and (varphi =0). When the flying mirror was moved to X₂, the beam is completely reflected. At this time, the AB and CD planes were transformed into A₁B₁ etc₁D₁, respectively. Therefore, the profile of the reflected field became the blue quadrilateral A₁B₁VS₁D₁. According to this analysis, the angle between the LM and the reflected field profile should be (varphi =0.403) rad, which is in good agreement with the simulation result of (varphi =0.424) rad, as shown in Figure 2b.

Diagram of the change in profile of the electric field. The red quadrilateral (ABCD) represents the profile of the incident electric field; the direction of the vector (overrightarrow{mathrm{DA}}) is defined as the direction of the incident profile. The blue quadrilateral (A₁B₁VS₁D₁) represents the profile of the reflected electric field and the direction of the vector (overrightarrow{{mathrm{D}}_{1}{mathrm{A}}_{1}}) is defined as the direction of the reflection profile. The angle between the LM and the electric field profile is defined as (varphi)where (smathrm{in}varphi /mathrm{sin}(varphi +{theta }_{in}+{theta }_{re})=beta mathrm{cos}{theta } _{in}/mathrm{cos}{theta }_{re}). X₁ represents the position of the flying mirror at the beginning of the interaction between the vortex beam and the flying mirror, and X₂ represents the position of the flying mirror after the interaction.

The above results confirm that the emission angle, wavelength and distribution of the reflected beam observed in the simulation are in line with theoretical expectations. In the next section, we focus on AM and examine the time history of the average OAM per photon of the electromagnetic field.

The average AM carried by a photon was calculated based on field data from PIC simulations using (j={varepsilon }_{0}{int }_{V}rtimes (Etimes B)mathrm{dV}/mathrm{N})where ({varepsilon}_{0}) is the dielectric permittivity of vacuum; r is the position vector; E and B are respectively the electric and magnetic fields; V refers to the entire simulation region for integration; and (mathrm{N}) is the number of photons in the entire laser beam. To accurately calculate the AM, we selected the electromagnetic fields for three periods in the middle part of the laser beam as shown in Fig. 2a. To intuitively display the simulation results, the angles investigated in this study were all angles along the + Xaxis. FIG. 4 shows the temporal evolution of the OAM carried by a photon; ({j}_{x}) and ({j}_{y}) refer to the two components of OAM in theXandtheredirections, respectively. To (t=12 T), the selected part of the vortex beam was incident on the left boundary of the simulation box. Before the vortex beam interacts with the flying mirror, ({j}_{x}=0.857) and({j}_{y}=0.491) were constant (t=12 T) at (t=19.5 T). Therefore, the OAM direction of the incident beam was 0.520 rad, which was collinear with the LM ( ({theta }_{in}=pi /6) rad) of the incident beam. To (t=24 T)the selected laser was completely reflected (the same three periods as the incident beam); ({j}_{x}=0.983) and ({j}_{y}=0.147) has remained constant (t=24 T) at (t=30 T). Therefore, the direction of the OAM of the reflected beam was 0.148 rad, thus indicating a non-collinearity with the LM of the reflected beam (according to the aforementioned result of(2.968) radi). The angle between the LM and the OAM is({Theta }_{0.5c}=0.320 mathrm{rad}.) Essentially, in addition to the longitudinal MA in the propagation direction, the transverse MA in the perpendicular propagation direction was generated by the interaction between the vortex laser and the flying mirror. This non-collinear phenomenon results from the profile change of the laser electromagnetic field caused by the double Doppler shift.

Time history of the average OAM carried by a photon. The black and red dotted lines represent the OAM in theXandtheredirections, respectively. The time is normalized to the period (T) of the laser beam and the OAM is normalized to(mathrm{hslash }).

New Delhi, July 16 (IANS): If India and China were to fight a war in the near future, India risks losing the war within ten days. China could take Arunachal Pradesh and Ladakh with minimal casualties, and India couldn’t do much about it, says military expert and best-selling author Pravin Sawhney.

It’s because the Indian army is preparing for the wrong war, says Sawhney in his revealing and disturbing book, “The Last War: How AI Will Shape India’s Final Showdown With China” (Aleph), as he explains in detail how this alarming scenario could unfold.

China’s war with India will be reminiscent of the 1991 Gulf War in which US military combat networks linking sensors to gunners and guided munitions with the support of space assets caused a shock and a fear among militaries around the world. Similarly, China’s war with India will stun the world with the use of artificial intelligence, emerging technologies, multi-domain operations, imaginative warfare concepts and human-robot collaboration. smart, writes Sawhney.

China has been preparing for this since the Doklam Crisis in 2017, after which it permanently increased its troops across the Line of Actual Control, leading to a stalemate that continued for two years without any tangible sign of resolution.

The author argues that China’s superpower status will only grow and the “capabilities mismatch” between the two countries will increase. And if there is outright war, the Indian military will be no match for the AI-backed Chinese war machines.

In such a war, traditional conventional forces will be at a huge disadvantage, nuclear weapons will have no role to play, and the valor of individual soldiers will be irrelevant.

India is honing its forces to wage war in the three physical domains of land, air and sea, while the PLA is striving to become the superior overwhelming force in seven domains – air, land, sea ​​(including warfare on the high seas), outer space, cyberspace, the electromagnetic spectrum, and near space (aka the hypersonic realm).

The PLA’s disruptive technologies will overwhelm India within the first seventy-two hours of the outbreak of hostilities and lead to the rapid end of India’s resistance, the author writes, as the main battlefield will not be not on earth but in cyberspace and the electromagnetic spectrum.

“The Last War” explains why it is essential that India works to prevent such a war from taking place.

He should avoid focusing on a joint fight with the United States, whose power in the region is weakening. Instead, India should seek to make peace with China and Pakistan, its main adversaries at the moment, while simultaneously working to build up its military and technological forces in areas it has not focused on. its resources. Only then will the country’s borders be firmly secured and the region’s future peace and prosperity assured, the author argues.

Sawhney has been the editor of the national security and defense news magazine FORCE since August 2003. The author of three books – “Dragon On Our Doorstep: Managing China Through Military Power” (co-authored with Ghazala Wahab), “The Defense Makeover: 10 Myths Shaping India’s Image”, and “Operation Parakram: The Unfinished War” – he was Visiting Scholar at the Royal United Services Institute for Defense and Security Studies, UK and Visiting Scholar at the Cooperative Monitoring Center, USA.

After thirteen years of commissioned service in the Indian Army, he worked with The Times of India and Indian Express – and with the UK-based Jane’s International Defense Review.

Sometimes an artist finds the community, but other times the community finds the artist.

In the case of Twin Cities-based artist/curator Gregory J. Rose, he wanted to find other artists working in Black Abstraction, so he put out an open call for an exhibition that would focus on exactly that.

“Since the uprising and George Floyd, art has been at the forefront of the past, of healing, of communication and of community,” Rose said. “I wanted to know who my peers were because I’ve lived here since 2001.”

His responses were collected in the group exhibition “Change Is God – Take Root Among the Stars: Black Abstraction in the Midwest,” currently on view at the Soo Visual Arts Center in Minneapolis. Seventeen artists who call the Midwest home — including one in Oklahoma who has advocated for that state as part of the region — make up the mix of two- and three-dimensional work in this exhibit, which includes painting, installation , quilting, video and sculpture.

abstract power

Abstract art is more like music in the sense of looking and feeling rather than immediately recognizing faces and places and then assigning meaning. In a 2020 academic study published in Proceedings of the National Academy of Sciences (PNAS), researchers found that abstract art can help people understand things more conceptually than realistically, evoking “distant” feelings. .

Eight of the performing artists have made the Twin Cities their home. Stephanie A. Lindquist’s four abstract photographs and lightboxes, arranged on the floor like a reproductive organism, are actually representations of mold that grows from Minnesota to West Africa.

Sarah White’s dynamic installation is a suspended white canvas with electromagnetic lines scribbled across it and a faint video projection of a black woman tying a rope around herself and then lying on the floor.

He was inspired by “what it’s like to have my hands on a body and feel their grief and think about how the heart has electromagnetic waves that go out 3 meters in every direction,” White said in a video on the SooVac YouTube channel.

Also on display is recent Guggenheim Fellow Ta-coumba T. Aiken, who recently closed a solo exhibition at the Dreamsong Gallery in northeast Minneapolis. Aiken, whose circular acrylic-on-canvas works “Time to Face It! Tell the truth” and “KEYes on the Prize” are on display, noted how abstraction is “not a new thing for African-American artists, to call ourselves abstract black artists.” He mentioned Alma Thomas, whose work is in the Whitney Museum of American Art, as one of the first black abstract artists.

“Then there are people like Norman Lewis, who was an abstract artist at the same time as Jackson Pollack, but art critics wouldn’t talk about him, probably because he was black,” Aiken said. “When I discovered his work, it was phenomenal.”

Part of Rose’s desire for the show was to move the conversation around black abstraction beyond the more well-known Twin Cities artists who worked there, such as Aiken, Seitu Jones and Clarence Morgan, with whom he studied. in the Department of Art at the University of Minnesota. .

Artist Alex Beaumont began his work around a personal project exploring his Jamaican nature.

“I’ve felt a bit tenuous or disconnected at times that I haven’t had a deeper relationship with the island and certain members of my family,” Beaumont said.

“In the work, I count with these feelings of loss and I feel this materially in the withdrawal of the threads of the work – this permeability of the work with the cut canvas – but I also claim my experience embodied in my Jamaican. .”

She uses fabric made from the sorrel plant. Her textile pieces also visually reference the iron work on her family’s home in Mandeville, Jamaica.

Beaumont grew up in South Carolina, but her father is from Jamaica and her mother is of German descent. She likens the way Jamaican culture spread to the breath of a dandelion’s seeds.

“It gave me a deep sense of comfort that, you know, the things that I feel and experience within the framework of [a Jamaican] The Diaspora really has this connective tissue with the other people in that Diaspora,” she said. “It was a great experience to be part of this show.”

The Indian aircraft carrier, INS Vikrant, completed the fourth phase of sea trials on July 10, which involved integrated testing of major equipment and systems on board, including some of the equipment in the aviation facilities complex, the navy said. Indian.

The ship is expected to be delivered at the end of July, after which it could be commissioned on August 15, coinciding with the 75th anniversary of India’s independence.

“Indigenous aircraft carrier Vikrant has completed the 4th phase of sea trials of major equipment and systems, including key aviation equipment undertaken with further performance improvement, in preparation for the delivery of the largest indigenous warship to Azadi Ka Amrit Mahotsav,” the Navy said in a statement. Tweeter.

The Navy has also released images of the new aircraft carrier, one of which shows INS Vikrant from a distance and the other shows a Naval Dhruv helicopter hovering above the flight deck. A MiG-29K fighter jet and a Kamov Ka-31 helicopter are also parked on the flight deck.

— SpokespersonNavy (@indiannavy) July 10, 2022

Designed by the Indian Navy’s Naval Design Directorate (DND), the Vikrant was built by state-owned Cochin Shipyard Limited (CSL) with 76% indigenous content, putting India in an elite club countries – USA, UK, Russia. , France and China – which can build aircraft carriers.

“The Indian Navy and Cochin Shipyard Ltd’s indigenous design and construction of an aircraft carrier is a shining example in the nation’s quest for ‘AatmaNirbhar Bharat’ and ‘Make in India Initiative’ with over 76% content native,” the Navy said. in a press release.

INS Vikrant’s first sea trials were completed in August 2021, after which the second and third phases of sea trials took place in October 2021 and January 2022, respectively.

During these three test phases, endurance tests were carried out on the propulsion machinery, electrical and electronic assemblies, deck machinery, life-saving appliances and the vessel’s navigation and communication systems.

Indian Vikrant vs Chinese Fujian

The arrival of INS Vikrant marks a significant increase in the Indian Navy’s power projection capabilities amid growing tensions with China and increasing incursions by the People’s Liberation Army (PLA) Navy from China in the Indian Ocean Region (IOR).

With two aircraft carriers in the fleet, even if one leaves for maintenance, the other will remain functional. In addition, the Indian Navy wishes to acquire a third aircraft carrier.

On the other hand, China also launched its aircraft carrier Fujian or Type 003 on June 17. Named after the Chinese province of Fujian, the Type 003 is China’s third aircraft carrier and the first with an all-indigenous design.

Experts suggest that Fujian is likely to be used to project Chinese power into the South China Sea (SCS) and Indian Ocean.

So far, China is not known to have released the detailed specifications of the Fujian, except that it has a displacement of over 80,000 tons, more than double the displacement capacity of 37,500 to 40,000 tons of the Vikrant.

Also, the Fujian is perhaps the largest non-US aircraft carrier in the world, with a length of about 320 meters and a width of about 73 meters, based on satellite images.

INS Vikrant is only 262 meters long with a beam of 62 meters and a height of 59 meters. It has 14 decks, five of which are in the superstructure and 2,300 compartments, and it can accommodate a crew of 1,700, including special cabins for female officers.

Based on ski jump ramp technology, Vikrant can operate short takeoff but stopped landing (STOBAR) aircraft with two takeoff runways and one landing runway with three arresting wires.

Initially, Vikrant will operate approximately 24 Russian-made MiG-29K fighter jets also deployed at INS Vikramaditya. However, the Indian Navy is also buying a fleet of deck-based fighter jets, for which it has shortlisted Boeing’s F/A-18E Super Hornet and Dassault Aviation’s Rafale-M (Marine).

In addition, the warship will also operate Kamov-31 helicopters, MH-60R multi-role helicopters and other locally built advanced light helicopters.

While Fujian has a much more advanced system for launching its aircraft, the Electromagnetic Aircraft Launching System (EMALS) allows the carrier to launch a wider range of aircraft.

The ski jump ramp on a carrier flight deck allows an aircraft to take off from a runway that is shorter than its required takeoff run but still powered by its power.

On the other hand, EMALS uses powerful magnetic fields generated by electromagnetic induction motors that power the catapults to propel the aircraft, much like the steam-powered catapults used in CATOBAR (Catapult Assisted Take-Off But Arrested Recovery) technology. ).

Compared to the ski jump ramp used by Vikrant, Fujian’s electromagnetic catapults can propel heavier aircraft at much faster speeds, allowing them to launch combat aircraft loaded with more ammo.

EMALS can also launch drones and large transport aircraft which are better than transport helicopters on aircraft carriers in terms of range, speed and cargo capacity.

Additionally, electromagnetic catapults can launch large reconnaissance aircraft equipped with Airborne Warning and Control Systems (AWACS), increasing the range at which adversaries can be detected in advance.

Fujian will operate the J-15T, a catapulted version of the J-15B that flies from STOBAR ski jumps aboard the Type 001 “Liaoning” and Type 002 “Shandong” aircraft carriers.

The J-15 Flying Shark is inspired by the Russian Sukhoi Su-33. It is currently the only carrier-based fighter in service with the PLA Navy, with the FC-31 ‘Gyrfalcon’ being tested and awaiting serial production.

Additionally, as previously reported by EurAsian Times, Fujian may eventually get an Electronic Warfare (EW) variant of the J-15, as will the US Navy’s EA-18 Growler EW aircraft based on the F/A- 18 Super Hornets; a next-generation stealth fighter believed to be the J-35; a fixed-wing early warning aircraft dubbed the KJ-600; armed reconnaissance drones and the Y-7 transport aircraft.

The United States Air Force (USAF) has awarded 27 companies – large and small – places under a multiple-award, indefinite-delivery, indefinite-quantity (IDIQ) contract worth up to $950 million. in support of the Air Force’s role in the Department of Defense (DoD) Joint All Domain Command and Control (JADC2) Battlefield Strategy.

The IDIQ contract will help develop and operate systems in the land, air, maritime, space, electromagnetic spectrum and cyber domains to support the JADC2 strategy.

The contract – awarded through the Air Force Life Cycle Management Center – will allow 27 contractors to compete for work related to the Pentagon’s ambitious effort to connect sensors and shooters in all domains into a single network. The Air Force Life Cycle Management Center will determine work locations with each contract order and expects work to run through May 28, 2025.

The JADC2 strategy envisions the creation of a massive “network of networks”, sharing intelligence, surveillance and reconnaissance from sensors in air, land, sea, space, cyberspace and the electromagnetic spectrum. , identifying the appropriate units or platforms to deal with threats, and connecting them with the necessary information. To realize this vision, the Pentagon will need to use advanced technologies such as artificial intelligence, machine learning, cloud computing and new methods of communication.

The Pentagon originally appointed 27 JADC2 contractors in May 2020 and has since added other vendors to support the program.

Japan may soon conduct the first combustion flight test of its under-development scramjet engine to advance its hypersonic technology.

The flight test could take place on July 23, 2022 at the Uchinoura Space Center of the Japan Aerospace Exploration Agency (JAXA), according to a statement given to Janes by the Japanese Ministry’s Acquisition, Technology and Logistics Agency. of Defense (MoD). (ATLA).

It is expected that the flight will provide crucial data that will drive the project forward.

The engine will power a variety of hypersonic vehicles, boosting the country’s ability to protect outlying islands, according to the report.

The goal of the research project, according to the ATLA, is “to acquire a model that estimates [the] in-flight combustion phenomenon in [the] scramjet engine. The organization added that the results would be comparable to information from ground-based wind tunnel testing.

To “correct and predict data during the actual flight,” the agency continued, it will also develop and evaluate numerical model analysis.

New advances in hypersonic technology from Beijing have become a major concern for Tokyo. Currently, Japan is looking to increase its investment in the development of hypersonic technology.

Japan’s hypersonic program

Hypersonic weapons can maneuver in flight and travel at speeds greater than five times the speed of sound, making them much harder to intercept. Russia and China have already deployed these weapons, which can be equipped with nuclear warheads.

In March 2020, Japan first announced plans to develop its hypersonic weapons, aiming to join a small group of nations including Russia, China and the United States. The strategic importance of these plans increases as there are indications that Tokyo may change its pacifist constitution to allow for greater military power.

Japan intends to deploy two types of hypersonic weapons: the Hypersonic Cruise Missile (HCM) and the High Velocity Flight Projectile (HVGP).

The HCM performs the same functions as a conventional cruise missile. It can be fitted with either an explosive penetrating warhead (EFP) for land attack, or an armor-piercing warhead intended to pierce the deck of an aircraft carrier.

Rather, the HVGP uses a solid-fuel rocket engine to raise its warhead to a high altitude before separating, from where it can glide at hypersonic speeds towards the target. It can also be equipped with many EFPs for area saturation attacks.

Collaboration with allies?

China has accelerated the development of hypersonic weapons, including carrying out tests in 2021 of a system that would deploy a hypersonic glider vehicle during an orbital bombardment. Japan is working with partners to develop sufficient capabilities to defend against these weapons.

In January 2022, the United States and Japan announced their intention to sign a new agreement to enhance their cooperation in research and development on emerging technologies focused on advanced space systems and hypersonic missile defense.

In a joint statement released after the meeting, U.S. and Japanese officials gave little information on the details of the R&D sharing agreement, saying only that “Ministers are committed to continued investment joint ventures that accelerate innovation and ensure the Alliance maintains its technological edge in critical and emerging areas, including artificial intelligence, machine learning, directed energy and quantum computing,”

Additionally, a hypersonic missile test reportedly conducted by nuclear-armed North Korea earlier this year prompted Tokyo to focus on developing anti-hypersonic technologies.
