Perfect conductor

I am trying to simulate a microstrip resonator. I see that when I use a Perfect Electric Conductor as the stripline surfaces, the wave propagates along the surface of the metal, but if I replace it with a metal, say, copper, the wave does not travel along the strip.

I am using the RF modules, Electromagnetic wave, frequency domain.

You haven't selected any boundaries in the impedance boundary condition.

Cheers

Thanks for the swift reply.

If I add an impedance boundary condition here, I am not able to select any boundary. It either says 'overridden', or 'not applicable'.

I think this is because the boundaries for impedance boundary condition should be the outermost boundaries, which, in this case, are the PMLs.

If I remove them, I still can't set an impedance boundary condition in the microstrip line, as it is the bottom surface of the copper layer.

Any way I could get around the problem?

Again, my goal here is to find the resonant frequencies and the Q factor for the resonator.

Thanks in advance.
