Imagine there is a 3D unit cell; I want to see if there is any way to simulate S parameters for the case the unit cell is infinitely extended in only one direction is finite in the other direction.

Obviously floquet port doesn't work. Inserting only wave ports didn't work because I have master/slave boundaries. I might use PEC instead of periodic boundary?
 

Hi violetcrow,

A PEC is a type of PBC. One PEC on it's own will simulate 2 periods (by image theory), while two parallel PECs will simulate an infinite array. Note that the same applies for PMCs. When I solve one dimensional dispersion, I apply PMCs to the sides (tangentially) of my simulation because I am only interested in TM modes - I could also do PECs to get the TE modes.

Alternatively, you can apply Master/Slave boundaries with a zero degree phase shift to get all modes.

Good Luck
