Surface acoustic waves, or SAW, are tools, that can create new acoustic levitation technology. The interaction with SAW waves and the electromagnetic fields makes those waves interesting for stealth technology. The SAW waves can also used to push gas away from the aircraft body and that decreases friction. The SAW waves are also suitable tools for the next-generation acoustic systems that can push materials on the layers. 

The surface acoustic waves are things. That can create so-called acoustic lasers that can cut nanomaterials. The SAW system can create surface acoustic waves in the tube-shaped structure. They can form acoustic tweezers that can move single molecules with ultimate accuracy. 

Things like phonons and SAW waves can create those soundwaves. In special chemical environments where chambers are filled with pure single gas that system can make the new wave of nanotechnology. 

The SAW waves can also make it possible to create new types of stealth and levitation systems. Quantum and nanomaterials are tools. That can be used to create strong SAW waves. 

But if the SAW waves can create pressure pulses that are powerful enough those systems can push objects above the ground. In real-world technology, levitation means silent hovering. That hovering can happen by using magnetic systems, or acoustic systems which means the system creates pressure waves that make it hover. 

The SAW waves in the material can also create sound waves, which can make things hover above the ground. Acoustic levitation is a tool that can be better and more multipurpose than magnetic levitation, called maglev. Maglev requires magnetic systems that press the thing upwards. And that is the problem with the maglev systems. The maglev systems can be put on things like airfields there they can push aircraft upward. 

However, if researchers want to make a levitation system that keeps the thing hovering without special platforms. The acoustic or pressure.-wave-based systems are effective. Those systems can also operate with non-magnetic materials like wood and carbon. And they can be the new tools for technology. 

The acoustic waves can put any material hover. And the acoustic wave-based systems are less vulnerable than propeller-using systems. The surface of the system must not always use things like metal. Some long-chain materials like box-shaped graphene structures can be used to create those loudspeakers that can be used to make the SAW waves.
