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 ...
An international team of researchers has just done the seemingly impossible: generate terahertz (THz) waves from water. Terahertz waves are a type of radiation with a wavelength shorter than ...
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 ...
