Hi all, I am trying to measure the polarization conversion of a half wave plate. In practice, I have a right-hand circularly polarized input plane wave (Ex+i*Ey) which propagates through a subwavelength grating acting as half wave plate (simulation is set in 3d). I would like to measure the polarization conversion, i.e. the amount of flux that is converted to left-hand polarization (Ex-i*Ey). Is there a way to measure the flux for a specific polarization (similar to 'add_flux')? I know I could simply output the fields and calculate the circularly polarized components as Ex±i*Ey for visualization, but I would appreciate a quantitative solution to measure the leakage term, i.e. the amount of flux which is not converted to opposite helicity.
