ＲＷＧ　port
Hello everybody,
I'm looking to find the equation of the impedance of a port in a Rectangular Wave Guide in HFSS.
Fo example, when i simulate a RWG i use two WavePorts non normalised at 50 Ohms, and then, HFSS gives me the impedance Zo (depended of the frequency).
I'm wondering what is the exact formula the software use ??

Thanks a lot Smile

zpi wave port hfss
In HFSS Zpi is calculated for the waveport by default.

Re: The impedance of a RWG Port in HFSS
hi,
In HFSS, they assume a RWG is connected to you model at the wave port. And I think, in additional, you may have a solution at Chapter III - Microwave Engineering - David M. Pozar after refering to waveport definition in HFSS tutorial.

Regards!
