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 ...
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.
Metasurface is a two-dimensional array of periodic or non-periodic structures that manipulate phase responses at the sub-wavelength scale for wave-front steering in refraction and reflection modes 1,2 ...
