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 ...

(Nanowerk Spotlight) Controlling how electromagnetic waves behave as they move through space is essential for technologies like wireless communication, radar, and remote sensing. Engineers have ...

Silicon solar cells reflect about a third of the light that they could potentially convert into electricity. A new nanostructured coating developed by researchers at Rennselaer Polytechnic Institute ...
