Hi, I have a question regarding the S11 response I get, when I simulate CPS, CPS,.. on HFSS. When I choose "Do not renormalize" in the waveport settings , I understand that the port is matched to the waveguide. Thus, I am expecting to see no reflection. However, what I notice is that S11 is very small at low frequency but increases to about -10 dB at 100 GHz. If I increased the accuracy of S, nothing new. Will am I missing something?
