how can i simulate TEM TM TE wave incident FSS WITH HFSS

in simulating FSS , I know how to simulate a plane wave incident FSS by different angle.
BUT

how can i simulate TEM TM TE wave incident FSS arrays with HFSS?

thank you for help

You can't. HFSS does not give you this information nor allow you to specify what modes to be input to the port.

cst can do what you want.in cst, you can choose the mode of incident wave.

thank you for your help. wish you a good weekend
