Ports and Floquet Boundary conditions

Hi,

I'm trying to build a 2D model showing total internal reflection, but am building it piece by piece to ensure the physics works. So far, I cannot get the ports and boundary conditions working for even a square area with excitation port on bottom, exit port on top, and Floquet boundary conditions on the sides. Air is the only material so far.

There's something very small and quick that's off about what I have--my emw.Ex and emw.Ey look great--plane waves propagating in the correct direction and everything, but emw.normE looks awful. Another oddity is that my Ex and Ey are incorrect for 45 degree incidence, but 20 and 60 look fine.

Given that Ex and Ey generally look good, I'm assuming it's got to be a relative phase thing (or my model is correct and I'm too dumb to realize it). When I plot sqrt(Ex^2+Ey^2) I get something that looks correct. When I plot sqrt(Ex*conj(Ex)+Ey*conj(Ey)) I get the same thing as norm.E of course, which looks incorrect. Any help is greatly appreciated!

Daniel
