Hi,
I am new to HFSS (a few weeks ago I was asked to learn it without any prior knowledge of it or antenna simulation), and I have a model of an Interdigitated Capacitor, which we are trying to find the capacitance of. I have a lump port across the two "digits" for an excitation and I recently added a dielectric(Polyamide, Er=4.3) and PEC under the capacitor(the cap will be applied to a metal surface). I plotted the Z parameters, notably the imaginary component as the real was ~=0. From this I calculated C from Z= 1/(jwC) \[\to\] C = -1/(2*pi*f*z), with ~=1pF results. My advisor liked this but wanted to know how HFSS calculates Z parameters. I tried to look online and through the help but I cannot figure it out. Any help would be greatly appreciated. I attached the file I've been using if that helps.

Thanks.
