Relations for the Fresnel reflection coefficients of a bimaterial interface independent of the angle of planewave incidence

Abstract

A relation between the Fresnel reflection coefficients, for parallel and perpendicular planewave incidence, applicable to a dielectric-dielectric interface has been given by Azzam, the relationship being independent of the angle of incidence. Here, that relationship is generalized to include magnetic properties as well. Connection is also made with the Brewster angles relevant to the two polarizations.
