Metasurfaces are a family of novel wavefront-shaping devices with planar profile and subwavelength thickness. Acoustic metasurfaces with ultralow profile yet extraordinary wave manipulating ...

The team’s analysis revealed unexpected connections between light and sound. “Sound waves are usually considered as simple scalar wave fields that lack any vector properties such as polarization and ...

Researchers have succeeded in detecting the rolling movement of a nano-acoustic wave predicted by the famous physicist and Nobel prize-winner Lord Rayleigh in 1885. A team of German and American ...

On the surface of the material, the acoustic wave generates an elliptically rotating (gyrating) electrical field. This, in turn, forces the electrons in the nanowire onto circular paths. “So far we ...
