Yes, I agree that AWR child group should be organized.
Similarly Keysight ADS ( and other derivatives such as Goldengate, EMPro, Genesys etc.) and Cadence/Orcad child groups will be nice.
I suppose that ADS child group will be very active and interesting.I'm saying that as a user of ADS since 2000.
Or, a simply a thread "RF , Microwave and Optical Engineering"
