| Definition: | an angle of incidence on a specular surface separating two perfect dielectric media such that the reflection factor is zero for a wave which has its electric flux density vector in the plane of incidence
NOTE 1 – In radio, the term Brewster angle is often used for the complement of the angle defined above.
NOTE 2 – For propagation from a medium of refractive index n1, to a medium of refractive index n2, the Brewster angle is arctan (n2/n1).
