Hi all, My experience=20 I work for some time designing power amp and mw circuit, using ADS, Mwoffic= e, cadence. I am now back to phd study (parttime) for EM stuff BTW 2.5D is more like a 2D simulator with some assumption to make it almost= a 3D...but not quite a 3D, therefore a 2.5D .Calculation only around the 2= D plane. It may be messy around all the contributors so we have to organize ourself.
