Hello, I'm a student trying to simulate an FSS (Frequency Selective Surface) in HFSS.
When I simulate it using a unit cell with a Floquet port, I get the results I want. However, when I create an array of these cells and set a Horn WR90 antenna as the port, I get different results from what I can see from the unit cell simulation.

Am I doing something wrong in my simulation, or is this type of simulation not accurate in HFSS?
