Parallel plate waveguide in HFSS

[sanketpatel2020]

Hi!
Greetings!

I have doubts in simulating parallel plate waveguide in HFSS. Would you please help me in this regard?

1. Two sidewalls of the parallel plates are assigned PEC boundaries. Do I have to assign PMC boundaries to remaining two faces (which are not actually sidewalls, as parallel plates have only two side walls, which are already assigned as PEC)?

2. Should it be a "Driven Modal" or "Driven Terminal" (in context of HFSS)?

3. Which Excitation: Waveport or lumped port or voltage port?

However at later stage, my aim is to simulate three parallel plates, where wave is applied to middle plate and the outside two plates are grounded.

Regards

Yes

They are the same for two-conductor systems. Driven modal is probably more simple.

3. Which Excitation: Waveport or lumped port or voltage port?

Which ever you want/need. Again, waveport is most likely most simple.
