Hello. I wanted to ask about that how to plot the absorptivity as a fuction of frequency at different angles of incidences for TE and TM incident radiation. As I'm simulating a metasurface I have used transition boundary condition on the top mettalic layer, impedance boundary condition on the bottom mettalic layer and a perfect magnetic condutor. Then in the port I have used the type of port as user defined with the electric field which has a magnitude of unity in y-direction and mode phase as zero. Propagation constant is a plane wave (emw.k). I'm trying to design the 1/4th part of the metasurface. So, I want to know how to apply incident angles in TM and TE modes.

Thank You!
