2 Questions: Surface Inductance, RF Voltage

Hi, I am doing my first HFSS simulation and seem to be stuck on a few (sadly simple) things.

- Is there a way of directly inputting a surface inductance? I found the 'boundary reactance' option, but I deal with superconducting resonator circuits with extremely high quality factors, which are very sensitive to such parameters. I dont mind approximating the reactance as constant for frequency ranges; its just not preferred.

- How exactly can one simply input an RF voltage (magnitude does not matter) into a 3D conductor. There is a ground conductor nearby that probably needs to be referenced, or is having it attached to the boundaries good enough? Simply having waveports at my in and out points doesnt seem to work.

Thanks for any help.

I figured out my wave port issue, but still would like to know if its possible to attribute either a material or just a solid structure with a specific surface inductance.
