hfss metal conductivity
Dear Sir,
I am doing a circuit simulation by HFSS. This circuit is working at 1 GHz. It is known that the skin depth at that frequency is almost 2 um. Therefore, usually I need the metal thickness to be 6 um. But the simulation results of the circuit with 0.2 um metal thickness and 1 um metal thickness are almost no different. Could you tell me why that happened? and How can I deal with that, should I add some additional skin depth mesh on the face of metal?
Thank you very much!
