HFSS Filter Question

Hi,

I'm designing a window-ed nickel sheet which will transmit certain frequencies and reflect others. I also want to vary the angle at which the radiation is incident upon the sheet and see the effects.

I know that if I want to assume an infinite array I should Floquet ports. If I want to use a finite array, what ports should I use and what settings should I use?

For a finite size you can use plane wave excitation but you will have to calculate the reflected power using field calculator yourself.

thanks.

could you explain to me how I would do that? I want to look at the transmission data.
