Hi, thank you. I want to simulate a metasurface that, when probed by light with circular right polarization, generates one beam with circular right polarization and the other one with left circular polarization. I simulate it with fdtd but when I calculate the transmissivity, it calculates of course the total transmissivity. I want to calculate it separately for the two polarization.

Decomposition of the output field can be a good idea? Have you any reference how to do it?


The paper I am trying to simulate is this one:  Multifunctional resonant wavefront-shaping meta-optics based on multilayer and multi-perturbation nonlocal metasurfaces | Light: Science & Applications (


and I want to obtain a figure like this one:
