Hi Guys
I am trying to simulate the effort of a 1mm copper connection with two 100 ohms impedance source at frequency 1GHz. I want to connect two 100 ohms impedance source directly together, but in real PCB, there always have a copper line which is about 1mm. Can anyone suggest ways to simulate the copper line effect using HFSS?
Thanks a lot
I am trying to run the HFSS simulation as an exercise. I did the following:
I create an box from (0,0,0) to (1,1,0.036) with copper materials.
I then need to set up the excitations on the surface (0,0,0)-(0,1,0.036) and surface (1,0,0)-(1,1,0.036). I choosed both lump ports and excitation is at direction (0,0,0) to (0,0,0.036) and same on the second surface.
Finally I draw an cylinder to surround the metal box and run the simulation.
It reports lump errors.
For the same structure I then change the port to waveport for the same setting, they complain about the operation frequency.
Can anyone suggest how to correct set up the excitation for the simulation? ( the simulation is to simulate the 1mm copper with two 100 ohms on both ends, the expected results will be no reflection at 1GHz for such a small wire.
Thank you
