For example, you can open the following built-in sample.

If you check the "Phase vs. Angle", you can see the phase delay introduced to S and P polarization. 








And if you check in Wiki page, you can find the phase delay for P polarization has a shift of pi compared to the result in OpticStudio.

Why is shift happen?
This is mainly about convention. There are two choices for phase shift for the reflected ray, either Abelès (thin film) or Nebraska Muller (ellipsometry).





A good explanations can found in the following documents:

The following is an abstract.








In OpticStudio, we use the thin film convention. Therefore, when calculating the phase retardance, the following equation should be used.
