I try to model a single wire in HFSS and export the RLC parameters. I modeled, simulated and exported a lump model. But the resistance of the wire is very small. It seems that the capacitance is reasonable. Please help me. thank you. the attached is the project and the exported lump model. the R should be about 100 om. But in the file it is about 2 om. Thank you.

Is there a reason you have no boundary conditions on the outside of your air box? HFSS will automatically set the boundaries to PECs in this case. My guess is, you're coupling to some other mode with these PECs.

In this case, the metal is inside the silicon dioxide, the boundary is ground or PECs. I think the boundary is OK. Yes, it seems that there is another parallel path for the wave. But i could not find this. PlanarMetamaterials , thank you.
