Underwater waves could also be used to reduce the risks of tsunamis and to improve their early warning systems.

Researchers report their insights on the emerging field of complex frequencies excitations, a recently introduced scheme to control light, sound and other wave phenomena beyond conventional limits.

“Metasurfaces are engineered materials that manipulate wave behaviour in ways that natural materials cannot,” said Zhong. “In ...

Use precise geolocation data and actively scan device characteristics for identification. This is done to store and access ...

Sound is a vibration that travels through air as a wave. These waves are created when an object moves back and forth, compressing and decompressing air molecules. The frequency of these vibrations ...

Researchers found a way to reinvent glass that is self-cleaning and doesn't need harsh chemicals to be water-resistant.

Sound is a vibration that travels through air as a wave. These waves are created when an object moves back and forth, compressing and decompressing air molecules. The frequency of these vibrations is ...

A group of international researchers have developed a way to use sound to generate different types of wave patterns on the ...

A new paper explains how signals oscillating at complex-valued frequencies could transform sensing, imaging, and ...

These recordings, along with high-fidelity audio recordings and computational fluid dynamics simulations, confirmed that this wave is the origin of the "ah" sound. "The pop's frequency is much ...

Think of the inversion like a lid, or barrier in the atmosphere. When sound waves hit that barrier, they do not disperse and ...
