Hello zIEM,
There is an Ansys Innovation Course regarding the simulation of a waveguide using HFSS, that may resolve most of your questions. Please, feel free to access it from here: Intro to Ansys HFSS Using a Waveguide Example Part 1 — Lesson 2 - ANSYS Innovation Courses
Regarding the de-embedding, yes, it works but for a defined (from the user) length.
If you want to have an impedance reference, I suggest renormalizing the port impedance to 50 ohms or any other value you desire. Keep in mind that port renormalization is a Post Processing effect. Thus, you will be able to switch this option after your simulation and compare its results without changing the initial simulation settings.
Best regards,
Jason.
