Term: Brewster's angle
Synonym1: Brewster angle

Definition: for an electromagnetic wave incident on a plane boundary between two regions having different refractive indices, that angle of incidence at which the reflectance is zero for a wave that has one of its vectors of electric field in the plane defined by the direction of propagation and the normal to the surface

Note 1 to entry: The vector of electric field is the electric field strength in optics, and the electric flux density in radiocommunication.

Note 2 to entry: In radiocommunication, the term Brewster's angle is often used for the complement of the angle defined above.

Note 3 to entry: For propagation from a medium of refractive index n1 to a medium of refractive index n2, Brewster's angle is arctan (n2/n1).
