WebBrewster's angle is a special incidence angle which results in P polarized being completely transmitted (i.e. the reflected beam is purely S polarized). It, like the TIR critical angle, depends only on the materials' refractive indexes. The refraction angle \theta_2 θ2 can be computed from Snell's law as WebUsing θB to represent Brewster's angle, the equation for Brewster's formula is: θB = arctan (n2/n1). Here's a breakdown of what this means. In our formula, θB represents the angle we're trying to calculate (Brewster's angle). The "arctan" you see is the arctangent, which is the inverse function of tangent; in a case where y = tan (x), the ...
