Thank you for the response pmunaga!
I do not necessarily want to look at 200 modes exactly, I just know that I probably need a lot more modes than 100 to do what I would like to do. I would like more than 100 modes because I want to calculate the backscatter from a somewhat periodic 2D array of metallic patches. Because of the periodic boundaries I use, energy will only be scattered off the infinite surface (because of the periodic boundaries) in certain directions, or Bragg modes. If I want a Bragg mode in the backscatter direction, then I need to change the size of the unit cell in order to accommodate that. Having a large unit cell (or many Bragg modes) means that I do not need to change the unit cell size as much, relatively speaking.
I am using HFSS in ANSYS Electronics Desktop 2020 R2, and I believe it definitely has a limit on the number of Floquet modes you can use in a Floquet port (see attached image). Is there a newer version of HFSS that does not have that restriction?
