Hello Ray,
In reply to your mail I wanted if you have any prefered software for
solving RLGC values. In your reply to odd-mode impedance you mentioned about
Apsim RLGC is it a stand alone field solver? Please tell me if you know about
any good stand alone solver, how to get it and where to get it.
Thank you.
Jayanta
