So-called Rayleigh–Bloch waves can release enormous amount of energy that can damage technical systems under certain circumstances. They only exist below a precisely defined cut-off frequency; above ...

Binaural beats are said to provide many of the same benefits as meditation: lower stress ... beat will depend on its frequency and the corresponding brain wave: Beta waves (13-16 Hz) occur ...

Researchers developed a low-cost, scalable terahertz amplifier that could be used to make antenna arrays that can steer and focus high-frequency terahertz waves, for applications like high-resolution ...

Strangely enough, however, there are isolated high frequencies at which ... we know that only vibrations with a low frequency can generate Rayleigh–Bloch waves," says Peter.
