How to calculate the co and cross polarized transmittance/reflectance in Comsol?

In Comsol, I want to calculate the Txx(transmittance to x polarized for incident x polarized), Txy(transmittance to x polarized for incident y polarized), Rxx, Rxy, and so on in comsol. S21/S11 never gives info about the particular polarization, it gives the overall transmittance and reflectance. But how to find these components in COMSOL?

There may be some shortcuts for your particular (unspecified) geometry and problem setup, but in the most general/arbitrary case, you can always fall back to doing it the old fashioned way. That is, inspect (e.g., plot, tabulate) the individual field components and compute the appropriate ratios of them.
