Polarisation rotation due to Metasurface-more questions
This is a continuation of my previous discussion.
(1) Polarisation state mean, as we know in FDTD plane wave source , we need to define the amplitude and phase difference for two orthogonal plane wave source for elliptical light. So i am looking for this that how to get amplitude and phase difference for each mode (at +45, -45 and 0 deg diffraction order) from polarisation ellipse analysis group?
(2) Yes i want to use polarisation state of all the modes so that i can verify the reciprocity, right? and i should get the linear light back. so that means i need six plane wave , 2 plane wave for each mode. can i use all six plane wave in the simulation?
Do you mean two plane source , with 0 deg and 90 pol input, a and b amplitude input, and phase difference which we can calculate from polarisation ellipse?
