A team of researchers has for the first time successfully used lasers to generate guided sound waves on the surface of a microchip. These acoustic waves, akin to the surface waves produced during an ...

Researchers at the University of Rochester have used surface acoustic waves to overcome a significant obstacle in the quest to realize a quantum internet. Surface acoustic waves are vibrations that ...

Absorption of low-frequency sound is a difficult engineering problem because long-wave sound energy is poorly dissipated. Traditional sound absorbing materials such as porous materials, ...

If you enter a room to see someone dancing their heart out in silence, no headphones in sight, don't be alarmed. They may be ...

Engineers have created a device that generates incredibly tiny, earthquake-like vibrations on a microchip—and it could transform future electronics. Using a new kind of “phonon laser,” the team can ...

This paper introduces a novel reconfigurable technique for partitioning the propagation of surface waves by utilizing a T-shaped structure and pathways established through the introduction of fluid ...
