Ocean waves could be an enormous source of power for the grid: In the U.S., the motion of waves along coastlines could generate as much as 1.4 trillion kilowatt-hours a year, or around a third of the ...

A group of international researchers have developed a way to use sound to generate different types of wave patterns on the surface of water and use those patterns to precisely control and steer ...

Acoustic frequency filters, which convert electrical signals into miniaturized sound waves, separate the different frequency bands for mobile communications, Wi-Fi, and GPS in smartphones. Physicists ...
