1. The problem statement, all variables and given/known data At a wavelength of 400nm, the semiconductor ZnSe has a complex refractive index n= 3.0+0.32i A) If 400nm is incidient from air onto ZnSe with θ=tan-1(NR) = 71.6°, What is the refraction angle of the transmitted wave? B) Calculate the magnitude R and phase shift ψ associated with the amplitude reflection coefficient r for p-polarized 400nm radiation incident at 71.6° C) If 400nm radiation with a unit polarization vector 1/√2[1 0] is incident at 71.6 on the air-ZnSe interface, find the unit polarization vector that describes the reflected radiation. [The matrix is vertical, not horizontal, I'm new with the formatting on this forum :) ] 2. Relevant equations 3. The attempt at a solution For part a, i tried using snell's law and just omitted the imaginary part, I'm not sure if it's the right answer because of that though. For the others, I have no idea where to start.
