A simple method to calculate S parameter is to get both s/p component and recombine them into one single S similar to the circular polarization. You can modify the analysis group to pick up two field components instead of the built-in single component.nHowever, since the max magnitude of S is 1, but Ex, Ey (suppose propagating along z) may have larger than 1 value So you may need to normalize it. nA more complicated method might be to get S from its definition by involving E and H, which is out of this forum scope.nn
