New metamaterials can control the ultrasound very accurately.

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.
