THANK you so much for this video , please can you show me how to extract the equivalent circuit from SIW topology [if the SIW cavity has CSRR and IDC (Interdigital capacitor )]that simulated in HFSS or CST ? then sketch it in ADS software

Dr. Nezami, Many thanks for providing these courses. I'm trying to design a transition from GCPW to SIW around 200GHz. Do you know if the principles in Pozar's book apply to my case? In most of your courses, you only worked with MSL, not CPW.
