Pivotal calls its metamaterials-based technology “holographic beam forming.” The technology is used primarily to support ultra-wideband 5G communications.
“OUR MOST PASSIONATE INVESTOR, OUR LEAD INVESTOR, OUR MOST IMPORTANT, VALUABLE PLAYER IS BILL GATES”
At the heart of the technology is a low-cost, low-power software-defined antenna which aims to improve upon the decades-old “phased array” beamforming technology that’s still in use today.
“Compared to HBF, phased arrays, which are often used in military applications, use a much higher cost, size, weight and power (C-SWaP) envelope,” said Brian Deutsch, CEO, Pivotal Commware, in an interview with FierceWirelessTech.

Access-in-Motion™ (AIM) refers to broadband connectivity among passengers in planes, trains, cruise ships, and so on.
Phased array antennas have been used for nearly 70 years in the military domain to great effect.
Phased array antennas are used in fields such as defense, communication, and space technology. (Common Applications of Phased Array Antennas | System Analysis Blog | Cadence)
Phased array antenna applications are not limited to broadcasting, satellite communication, optics, weather research, and human-machine interfaces.

The advantages of beamformers in the battlefield are clear. Directional, beamformed antennas offer inherently low probability of intercept as the narrow beam focuses energy in the direction of the intended recipient while minimizing transmission in unintended directions.

For years, the U.S. military has explored using weapons much like the phasers on “Star Trek” that could be set to kill or merely stun.
The hallmark of all directed-energy weapons is that the target — whether a human or a mechanical object — has no chance to avoid the shot because it moves at the speed of light. At some frequencies, it can penetrate walls.
Since the ammunition is merely light or radio waves, directed-energy weapons are limited only by the supply of electricity. And they don’t involve chemicals or projectiles that can be inaccurate, accidentally cause injury or violate international treaties.
“When you’re dealing with people whose full intent is to die, you can’t give people a choice of whether to comply,” said George Gibbs, a systems engineer for the Marine Expeditionary Rifle Squad Program who oversees directed-energy projects. “What I’m looking for is a way to shoot everybody, and they’re all OK.”
Almost as diverse as the electromagnetic spectrum itself, directed-energy weapons span a wide range of incarnations.
Among the simplest forms are inexpensive, handheld lasers that fill people’s field of vision, inducing a temporary blindness to ensure they stop at a checkpoint, for example. Some of these already are used in Iraq.
Other radio-frequency weapons in development can sabotage the electronics of land mines, shoulder-fired missiles or automobiles — a prospect that interests police departments in addition to the military.
A separate branch of directed-energy research involves bigger, badder beams: lasers that could obliterate targets tens of miles away from ships or planes. Such a strike would be so surgical that, as some designers put it at a recent conference here, the military could plausibly deny responsibility.
Such issues recently led the Pentagon to delay its Project Sheriff, a plan to outfit vehicles in Iraq with a combination of lethal and nonlethal weaponry — including a highly touted microwave-energy blaster that makes targets feel as if their skin is on fire. Sheriff has been pushed at least to 2006.
The directed-energy component in the project is the Active Denial System, developed by Air Force researchers and built by Raytheon Co. It produces a millimeter-wavelength burst of energy that penetrates 1/64 of an inch into a person’s skin, agitating water molecules to produce heat. The sensation is certain to get people to halt whatever they are doing.
Military investigators say decades of research have shown that the effect ends the moment a person is out of the beam, and no lasting damage is done as long as the stream does not exceed a certain duration. How long? That answer is classified, but it apparently is in the realm of seconds, not minutes. The range of the beam also is secret, though it is said to be further than small arms fire, so an attacker could be repelled before he could pull a trigger.

The new system will be capable of scorching the target; blinding the target system’s sensors “through broadband supercontinuum generation in the air, and the generation of a localized electronic interference used to overload a threat’s internal electronics,” as stated in the brief.

Most of the Pentagon’s current research in directed energy weapons concerns continuous-wave lasers, which use a relatively low-power, high-energy beam to burn out optical sensors or gradually cause other material damage. But defense leaders are increasingly interested in ultrashort pulse lasers (USPLs), unimaginably high-powered beams fired for a tiny fraction of a second to vaporize a small portion of a target’s surface or disrupt its electronics.
Directed energy weapons (DEWs) are defined as electromagnetic systems capable of converting chemical or electrical energy to radiated energy and focusing it on a target, resulting in physical damage that degrades, neutralizes, defeats, or destroys an adversarial capability. Navy DEWs include systems that use High Energy Lasers (HEL) that emit photons, and High Power Microwaves (HPM) that release radiofrequency waves. The U.S. Navy uses DEWs for power projection and integrated defense missions. The ability to focus the radiated energy reliably and repeatedly at range, with precision and controllable effects, while producing measured physical damage, is the measure of DEW system effectiveness.
Of particular research interest are efforts that offer breakthroughs in precision dynamic engagements against multiple maneuvering targets with selectable effects (hard kill, sensing, non-lethal), and those offering deep magazines, low cost per shot and “lowest” to zero collateral damage.
The U.S. Army is building the world’s most powerful laser weapon, capable of vaporizing targets and interrupting adversaries’ technology signals. The weapon is over one million times more powerful than any other laser developed before, NewScientist reported.
According to the Small Business Innovation Research (SBIR) website, the laser system, known as the Tactical Ultrashort Pulsed Laser (USPL) for Army Platforms, will stand apart from current lasers by emitting short pulses that rely on low energy, unlike current lasers which typically produce continuous waves.
The laser weapons would change how the military combats fast-moving, small drones and missiles, as well as human enemies, with human reactions ranging from skin irritation to blindness.
“These kilowatt-class CW laser systems predominantly engage targets via absorption of light; either causing the target to burn and melt or overwhelming optical sensors with high intensities,” the brief stated.

“This weapon can speedily fire metal-vaporizing pulses, just like a machine gun. It can easily vaporize its targets and disrupt enemy tech signals.”
https://ehtrust.org/5g-millimeter-wave-energy-may-penetrate-deeper-than-predicted/
“While MMW are almost completely absorbed within 1-2 mm in biologically equivalent tissues, it may penetrate much deeper in a live human body.”
“When a very fast pulse of radiation enters the human body, it generates a burst of energy that can travel much deeper than predicted by conventional models (Oughstun 2017). This induced radiation pulse is known as a Brillouin precursor. Brillouin precursors can be formed by ultrawideband radiation and by high-speed data signals as used in 5G.”

Nowadays, biological and health effects of 5G communication, which will use microwaves of extremely high frequencies (millimeter waves MMW, wavelength 110 mm), are of significant public concern. It follows from available studies that MMW, under specific conditions of exposure at very low intensities below the ICNIRP guidelines, can affect biological systems and human health.
To what extend the 5G technology and the Internet of Things will affect the biota and human health is definitely not known.
However, based on possible fundamental role of MMW in regulation of homeostasis and almost complete absence of MMW in atmosphere due to effective absorption, which suggests the lack of adaptation to this type of radiation, the health effects of chronic MMW exposures may be more significant than for any other frequency range.
Holographic beam shaping using a spatial light modulator (SLM) provides flexible adaptation of the intensity profile in laser material processing. This dynamic beam shaping is advantageous regarding the adaptation of accurate and efficient ultrashort laser based material ablation processes.
The Pentagon is working on the next laser weapon for the US military and it is intended to creep out the enemy rather than to hurt or maim them. The idea is to have a floating ball of plasma that also creates sounds with just the interaction of two beams of laser light out of thin air.
Scientists are now able to create sound, heat, and light from lasers. And, soon we could have full range of sound and voices as well as life-like projections. The report says that it is possible to project heat, light, and sound to about a kilometer away using just a 5-inch lens. This could help the military send voice messages to soldiers far away. An aircraft can also simulate gun fire on a region it flies over using this technology. The possibilities are virtually endless.
This tech, paired with a capable AI, can probably bring out the eye of Sauron meets HAL nightmares to life.

The content or 3D animations are projected around the product, as the fast movements and dynamic elements, attracts the attention of each person that passes through. People get shocked and enchantment as they try to guess how they function. They stare at them as if there was magic, but instead pure technology is behind.

Lumotive has created what Akselrod calls a “secret sauce” of liquid crystal sandwiched with printed silicon circuits. The company’s chips have tiny tunable antennas that can sweep laser light across a 120-degree field, and read what’s reflected to build up a map of its surroundings up to 20 times a second.
If only these forces were being used for good. The uses would be endless... my mind is a flutter with ideas that would help the world and each other with this technology. Your questions are shared by all of us who simply want the world to live in peace and love. Why is that so hard?
Bill Gates needs to take an early retirement
