Acoustic frequency filters, which convert electrical signals into miniaturized sound waves, separate the different frequency ...

Water waves can be used to visualize fundamental concepts, such as spin angular momentum, that arise in relativistic field theory, RIKEN physicists have shown 1. This will help to provide new insights ...

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 ...

SIAM Journal on Numerical Analysis, Vol. 52, No. 4 (2014), pp. 2073-2091 (19 pages) In this paper, we present and analyze a new finite difference method for computing three-dimensional wave maps into ...

A striking demonstration of a means to boost the information-carrying capacity of radio waves has taken place across the lagoon in Venice, Italy. The technique exploits what is called the "orbital ...

A recent preprint claims that we may someday be able to create gravitational waves in a lab. Through the use of “twisted” light, we could create powerful, high-frequency waves in a controlled setting.
