Brewster's angle equation
WebBrewster’s Angle. From derived reflection coefficients for TE mode in Fresnel Equations, the reflection coefficient for perfect dielectric can be written as. r T E = ( ϵ 1) 1 / 2 cos θ i − ( ϵ 2) 1 / 2 cos θ t ( ϵ 1) 1 / 2 cos θ i + ( ϵ 2) 1 / 2 cos θ t. With Snell’s law of refraction shown in Eq. (325), above equation can be ... WebNov 13, 2015 · When considering the incidence of non-polarized light on a flat insulating surface, there is a unique angle at which the reflected light waves are all polarized into a single plane. This angle is commonly referred to as Brewster's angle, and can be easily calculated utilizing the following equation for a beam of light traveling through air:
