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 (part-time) 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.
Cheer
Fred
