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

IT has been well established 1,2 that, in the case of diffraction of light by very-high-frequency sound waves only the first order of diffraction appears in the field of view and it attains the ...

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 ...
