Microwaves are tools for the new recycling methods.

New materials require new recycling methods. Some of those methods can be suitable for weapon applications. 

Microwaves break the carbon chains in polymers. And that makes them dangerous. There are tested microwaves to destroy oil in oil damages. The microwave cuts the polymer structures. And the same systems can destroy diesel and petroleum in their storage. Things like graphene are ultimate materials but only if they can conduct energy out from them. If the energy transmitter surrounds the graphene structure and starts to send energy into its outer edge that thing causes a situation in which energy starts to travel in the middle of the graphene structure. 

In this case, the system creates a standing wave in the middle of the graphene structure. The energy level in the outer edge is higher than in the middle of the graphene, which denies the graphene's ability to remove energy from the structure. The problem with recycling is this: recycling means breaking the materials. 


Microwaves can destroy Kevlar and other carbon-based chemical structures. 


The new way to recycle bulletproof Kevlar can also give the possibility of breaking the Kevlar armor. In those systems, the microwave cuts the kevlar structure. There are tested microwaves on the battlefield whose purpose is to jam drone swarms. The same systems can destroy kevlar armor and other plastic structures like composite magazines and plastic structures in weapons. Kevlar is also structured in the super-hard ropes used to keep offshore oil platforms in their position. 

The microwave also heats metals. That means microwaves can detonate ammunition in boxes. It can affect large-scale entireties like drone swarms. The big drones are good targets for lasers and machine guns. However, the drone swarms of small-size drones require systems that can affect the entire swarm at one time. 

Kevlar is used in bulletproof vests and lightweight armor in light vehicles. The ability to break kevlar opens the route to the ammunition. And that is a big threat to the law enforcement and military operators. Kevlar is also part of the structural composite armor metal. Kevlar plates are layer over layer. The kevlar structure keeps different metals away from each other. In those structures, the harder and softer layers follow each other. 

The purpose of the softer structure is to pull impact energy and the harder structure breaks the ammunition.  And that makes composite armor more effective than traditional armor. The microwave system that impacts microwaves to the kevlar structures breaks the polymeric chains in that strong material. The microwaves can break the bulletproof vests and other armor. 

There are used polymer carbon chains. And that makes microwave systems effective tools. Also for boosting ammunition power. There are tested microwave systems whose mission is to jam the tank's counter-missile system detonate its reactive armor off the ammunition's road and heat the metal armor that offers the warhead a better way to penetrate the armor.

New metamaterials can control the ultrasound very accurately.

(ScitechDaily, Sonic Breakthrough: MIT Unlocks Ultrasound Control With Advanced Metamaterials)

The cage around the nanotubes is the key to this new metamaterial. The structure around the nanotube and echo chambers can make the system a more effective sound controller than previous structures. The new structure in the metamaterials makes it possible to create smaller acoustic systems. That can make coherent ultrasound waves. That system can used in the new treatments that base the resonating micro-or nanoparticles. 

When a thing like micro-organisms like bacteria eat the nano-resonator. The ultrasound makes that nanoparticle resonate. That forms the pressure waves or nanobubbles in the organism. 

In cancer treatment nanoparticles. Like fullerene or graphene bites. Will be delivered to cancer cells. Then the ultrasound systems can give highly accurate acoustic signals to points where the non-wanted tissues exist. 

The highly accurate ultrasound control gives new visions to medical and other systems. A difference between ultrasound X-ray and other electromagnetic radiation is that ultrasound doesn't cause electromagnetic stress into the structure. The soundwave forms when molecular structures oscillate. 

Acoustic waves are not without dangers. The high-power acoustic waves can destroy things like DNA molecules. Or they can destroy things like hemoglobin molecules. Or simply smash tissues to flat. In that case, the cell turns into an empty bag. 


And that oscillation sends pressure waves to the medium. The thing is that ultrasounds can make many things in the industry. They can control how smooth the shell of the object is. That is one of the purposes of the ultrasound. 

Another thing is that ultrasound offers one of the most interesting ways to destroy cancer and bacteria. The ultrasound system can smash things like DNA, mitochondria, or other vital structures from cells. High-power ultrasound can also cut things like concrete and metals without heat. Ultrasound systems can make things like nanobubbles. 

In medical use those nanobubbles that form when the ultrasound system puts the blood cells rotate can close blood vessels during surgical operations. They can used to fill bacteria and other non-wanted cells. 

The new sonar systems that can observe tissues and search for things like tumors are also new tools for hunting submarines from depth. The precisely controlled coherent ultrasound bundle can used to track submarines. 


Or they can map tissues and materials.  Even the softest materials have hard points. The foam rubber might look soft. And its bounds soundwaves effectively. But it's possible. That ultra-thin soundwaves can jump from the walls of the bubbles in the structure. 

In weapon solutions, acoustic wave features turn into a harmful effect. That is used to harm persons or systems on purpose. 

Acoustic weapons like LRAD are tools that can control riots or disturb things like snipers. But high-power acoustic weapons can cut metals. They can cause damage to the submarine's hulls. Or they can put metal structures in the concrete wall to oscillate. 

The oscillation can cause damage to the ammunition or the cannons. And the little distortions in the high-pressure systems are always dangerous. They can break things like fuel injection systems or the tubes from power plants. 

In some models, high-power acoustic systems can make sound waves that are as strong as steel. Those soundwaves or pressure waves can turn even ballistic missiles or some other things like bombs out from their course. They can also destroy things like drone swarms. 

The ultra-and-infrasound systems can also make the person ill. Those systems can cause problems with concentration. So if that kind of system is targeted at submarines. They can make the crew unable to operate. 

In the same way, acoustic weapons can oscillate the bones. Those systems strip the concrete from the structure. High-power acoustic systems can also cause distortions in the jet fighter canopy. The high-power acoustic systems can also make things like the red blood cells rotate horizontally. That creates the nanobubbles in the targeted creature's blood vessels.

Cosmic web and dark interaction.

The magnetic shockwaves that illuminate the cosmic web don't form without reason. In that phenomenon, something pumps energy into the magnetic objects like neutron stars or magnetic fields.  That releases a very strong magnetic pulse to the cosmic web. An interesting question is: where does that energy come from? 

The cosmic web is the largest known structure in the universe. That web connects galaxies with each other. In some models, plasma flows are between stars and even between galaxies. The cosmic web is the material that accumulates around something. That something can be the chain of dark matter particles. 

Called weakly interacting massive particles, WIMPs. The WIMP is a mysterious thing in the universe. Sometimes researchers think that WIMP is some kind of quasiparticle or maybe a miniature black hole. Or maybe WIMP is a virtual particle, the energy shadow that forms on the opposite side of the particle. The energy or quantum shadow makes a situation where the energy tries to fill that shadow. 

And that means the WIMP could be some kind of energy field that acts like a particle. One of the explanations can be the standing gravitational waves. The only known thing is that. There is some kind of gravitational effect that the source is unknown. In those models, dark energy can be the energy that primordial or quantum-size black holes can send while they vaporize.

The accelerating expansion of the universe can have two reasons. 


1) The gravity turns weaker. 


2) Some kinds of small high-energy objects like primordial black holes can release energy stored in them. 


The model means that when quantum fields around particles turn weaker and material in the universe turns less dense that means the vaporization in things like black holes accelerates. That means. It's possible. That dark energy and Hawking radiation could be the same thing. 

But then we can look at the newest observations about dark matter and try to complete its models we can see that dark matter can form similar structures as visible material. So, dark matter can form things like black holes. Dark matter interacts with black holes through gravitation. 

When we try to explain things like the cosmic web we can see that there is some kind of gravitational effect that forms the web. There is something that forms that web. Nothing happens by itself in the universe. There is energy that makes things happen. While energy moves that cause actions. Every action requires energy. And standing energy doesn't do anything. Energy must move so that it can make something.

Things like power loss are the reason for the nature of wave movement. When an object sends energy to another object the energy sector expands. So a long-distance major part of the energy doesn't hit the object. Anyway, the ball-shaped particle sends wave movement into a ball-shaped form, and only a small part of the energy will impact the receiving particle. 

When we think about things like spin spinning particles like neutrons can collect wave movement into the middle of itself. Then it can turn that radiation into an energy beam. The idea is that. Extremely fast spinning particles can collect energy into it. And then that thing forms the energy pike that travels out from its axle.

The black holes and material do not form energy. They store energy in a new form. And when those objects energy levels turn high enough, the energy flow turns away from those objects. Sometimes gravity is explained using vaporizing ice as the model. When we put ice on the hot layer the ice starts to send vapor. During that process, the ice bounds energy and transfers it into vapor. And that decreases the temperature of the layer. 

The energy travels to that point from other places. And if that thing happens in the universe that energy is the quantum field that transports particles into that point. So in the universe layer is the Higgs field and the heat is the effect that pulls energy out from that field. 


Above: The Cosmic Microwave Background, CMB (Wikipedia, Cosmic microwave background). Does the dark energy background look like this? 

The dark matter is the mystery. There is a possibility that dark energy forms when WIMPs send wave movement. But today researchers know that dark matter and dark energy might not have cosmological constant. That means. The dark energy can form similar structures. As the cosmic microwave background. And we know that there are galaxies without dark matter. 

That means. Dark matter can create similar forms as visible matter. So there can be giant dark matter clouds in the universe. The stable environment can cause a situation where the energy strings can travel past the energy potholes like exciton. In that case, the energy string closes other energy impulses away. And that denies the weak outside field filling the pothole. 

So when we think about things like Einstein's Theory of Relativity and the MOND (Modified Newtonian Dynamics) we face one interesting question: can both of those models be right? Researchers tried to find the mistakes from Einstein's models and Einstein was right again. 

Sometimes difference between two models forms from the direction where we close that model. If we remember things like Newtonian gravitational models we can see that. They are suitable tools for certain scales. The scale and needed accuracy determine what theory, model, and formula we use.
