Generalization of Fresnel Equations?

[Abtinnn]

Hi guys!

I was wondering if there is a generalization to the Fresnel equations. Those equations calculate the reflective and transmissive coefficients, but it depends on the polarization of the incident ray. Is there a formula that could calculate those constants for an unpolarized incident ray? Thank you!

An unpolarized ray is just the sum of the two polarizations in equal amounts. The two special cases and their superpositions allow to solve every problem, there is nothing to generalize.

 

[Dr. Courtney]

An unpolarized ray is a superposition of two polarized incident rays.

oh!
Sorry I was too dumb to realize that!
Thank you! :)

This is about as general as it goes: reflection off an anisotropic medium:
