Waves close wavesVibrations that transfer energy from place to place without the transference of matter. - including sound and light - can be reflected at the boundary between two different materials.

Refraction close refractionProcess by which a wave changes speed and sometimes direction upon entering a denser or less dense medium, eg a light ray changes direction when refracted by a lens. of ...

A newly developed metasurface-based silicon antireflective coating combines rectangular and cylindrical meta-atom geometries. The metasurface achieves just 5 percent reflection, compared to ~50 ...
