You're most welcome,. The S-parameter calculation relies on grating projection, where we get the S and P polarization for the grating order. So you should be able to determine whether the output is LCP or RCP by comparing the phase of each polarization. nYou could also use the polarization ellipse to check if the output is still circular polarization. That said, I'm not sure if it would be possible to separate the output in RCP and LCP.nn
