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 ...

To investigate the reflection of light by different types of surface, and the refraction of light by different substances. Remove the block. Join the crosses to show the paths of the light rays ...

Researchers at the University of Washington, Seattle have found a way to recover images of the world that are reflected in a bag of potato chips. Using commercially available RGB-D sensors—which are ...

Concluding our series on reverb, we tackle the behaviour of sound and reverb reflections in actual, physical spaces. Jumping once again into our discussion of reverb, let's start with another useful ...
