Port Termination in HFSS

  Hello everyone
  I am doing a HFSS simulation which includes the overhead transmission line conductors. I want to put matched impedances at the end of each line to remove the reflections. Can I define a port at the end of each cylindrical conductor and terminate the port with a matched resistance (in the edit sources tab)? And if so, do I need to connect the conductor to the ground?

  Yes, you will want to define a port at each end of the conductor - the ports will be defined between conductor and ground. If your solution type is DrivenTerminal, you may use Edit Sources to terminate one of the ports with a matched resistance value (you will need to toggle "Terminal Excitation Type" to Total Voltage in the Edit Sources window first).
