EBG simualtion on CST using FSS template

Hi,

I'm trying to simulate the attached structure on CST using the FSS template.

I don't really know how to assign the excitation signal (wave port), can you please take a look?

I tried creating a wave port at Zmin, but received an error "Port 1 is defined on the Floquet port boundary at Zmin, and will be ignored"
