IEVref: 705-04-20 ID: Language: en Status: Standard Term: Brewster's angle Synonym1: Brewster angle [Preferred] Synonym2: Synonym3: Symbol: 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).
