Dear Members,
My comsol model for reflection from IR metasurface giving very high Reflection intensity from Pwaves. The reflection result from comsol model for S-Wave with settings {E0(0,1,0) incidnet angle 80 degree} using periodic boundry conditions is fitting well to experimental results while reflection results from comsol model for P-Wave with settings {E0(1,1,0) incidnet angle 80 degree} using periodic boundry conditions is not fitting well to experimental results as it is giving 5 times higher reflection. Please if someone can give any hint to change mesh size/step size of wavelength or boundry conditions etc.
Thanks in anticipation.

i meet the same question like yours but the opposite one。P-wave is ok.but the S-wave is totally wrong,And my 3D model is about the simulation of a interface between air and a kind of anisotropic media.By the way,both the results are ok when the model is 2D.So if you can solve the problem,please tell me the solution.Thank you very much.
