We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

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 (nature.com)

 

and I want to obtain a figure like this one:
