I am currently trying to figure out how to set up a basic electromagnetic wave propagation experiment hitting a sample at some angle of incidence. The module I'm using is Wave Optics at the Frequency Domain, and I'm looking into 2D simulations.
To just test out the waters, I'm trying to simulate a very simple setup with just a single rectangle of air. I have two ports on the top and bottom of the setup, the top being the excitation port. I'm trying to make the two boundaries on the sides to be PMLs and not periodic BCs. I suppose I should use the Scattering Boundary Conditions, but I am not quite sure how to specify the parameters of it.
My question is: How should I specify the excitation port to produce a propagating plane wave at an angle of incidence? I've been trying to play around the the propgation constant parameter and manipulate the electric field amplitude to be angle-dependent in the proper way, but all it has caused are weird electric field patters that don't resemble a simple propagation at an angle. I may be glossing over another parameter which I must work with, but I am not sure how to take it from there.
I believe I have succeeded perforiming something similar in 3D, since it has the option to setup the pitch-yaw-roll angle of the k-vector. However, I did not see something like that in 2D.
I appreciate any help in advance that could shed some light into the right direction (pun totally intended).
