1. The problem statement, all variables and given/known data
Let $$\sigma^+$$ light [left circular] be incident on a piece of glass, with incidence angle = $$45^\circ$$. Characterize the polarization of the reflected light.

The attempt at a solution
My first thought is to simply treat the components of the electric field (Ex,Ey) as separate waves and then rejoin them after the reflection has taken place. The problem is I am sure there is a phase change in here and I am not sure how to to show that.

I also think there might be an easier way to solve the problem without having to separate the wave into its Parallel and perpendicular components.

Any input is appreciated.

Thanks.

unless i'm missing something, i think you will have to break it down into components as the transmitted amplitudes of each will be different.

shouldn't be too hard to do by balancing the field at the boundary interface if i remember right, the phases should just fall out of the balance

that is if its a quantitaive question, otherwise it may be a more qualitative question...
might be worth checking what the brewster angle is as well...

brewster won't be 45 though ;)
