Sound waves, light waves and other types of waves, generally spread freely through space and over time. In 1958, physicist ...

Researchers have pioneered the use of parallel computing on graphics cards to simulate acoustic turbulence. This type of simulation, which previously required a supercomputer, can now be performed on ...

Electrons start behaving strangely when they are squeezed into extremely flat sheets such as graphene, which is just one atom thick. This makes graphene a promising material for generating robust ...

Parametric acoustic waves exploit the nonlinear interaction of high-frequency ultrasonic beams in a medium to produce low-frequency sound with exceptionally narrow beamwidths. By transmitting two ...
