Question About HFSS Port Renormalizing

[Mads Hedegaard Larsen]

I am currently running a simulation on a transmission line where i use two lumped ports:

Port 1 have an Impedance of 50 Ohm
Port 2 an Impedance of 10 kOhm - 132j Ohm

I am looking at the coupling between the two ports, in other words: S12
So should I run with both ports renormalized to get the correct S12 or not?

Thanks a lot,
Mads


Ps. I noticed that by default, lumped ports are renormalized to a 50 Ohm full port impedance, which means that the renormalization only really matter for port 2.
