Brewster's angle

[¦brü·stərz ¦aŋ·gəl]
(optics)
The angle of incidence of light reflected from a dielectric surface at which the reflectivity for light whose electrical vector is in the plane of incidence becomes zero; given by Brewster's law. Also known as polarizing angle.

In creating a directional light filter, MIT physicist Yichen Shen and his team knew that at the interface between any pair of materials, light arriving from one specific angle, known as the Brewster angle, can simply pass through unimpeded --it won't get reflected or bent.
Knowing an interface's Brewster angle provided a way to allow light from a desired angle to pass through, but Shen's team had to figure out how to block the light from all other directions.
