I'm having some problems trying to implement circularly polarized light in COMSOL Muliphysics.
For a isotropic homogenous media, I've obtained without problems the TE and TM reflectance curves. Following the Fresnel Equation application tutorial, I've defined a periodic port for incident light with Ex=1 Ey=i Ez=0 and output periodic port with Ex=1 Ey=i Ez=0. Then, I just insert Floquet periodic boundary conditions over the x and y planes of my rectangular structure. The results are somehow so goofy.
What do you think? is there any missing condition I've forgotten?
