Ocean waves have long been seen as having huge potential as a source of renewable energy. Waves produce an estimated 50 ...

By containing the sound wave on the surface of a chip, it can more easily interact with the environment, making it a perfect candidate for advanced sensing technologies. The findings are published ...

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

Fundamentals of sound systems design & engineering for a variety of entertainment ... hair bands, punk, disco, new wave, synthpop, hip hop, grunge, and mainstream pop. Covers the musical, historical, ...

Researchers have reviewed metamaterials to emulate Schrödinger dynamics, bridging classical wave physics and quantum ...

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 ...

The process is very similar to ultrasound imaging. However, the sound waves used are within normal hearing range, and they are used to identify objects rather than internal structures. This ...

Well, it's all to do with the strength of the vibration. A weak vibration makes a gentle sound wave which doesn't travel very far. Be quiet! A vibration with lots of energy makes a very powerful wave.

My research group has just published a paper demonstrating how underwater sound waves can be used to make surface waves more powerful, potentially making them a more viable source of energy.
