Hi OM,
You are treading water here. There is more than radiation at work
very close to an antenna. Consider your own language above: Induction
(or even capacitive coupling).

I think Richard has hit the nail on the head. I wish calculation of
electromagnetic fields could be reduced to a simple equation. Any
undergraduate text on electromagnetics barely scratches the surface. I
suggest you check the site at
www.nec2.org and download the .pdf version of
the "NEC Program Description -- Theory". Gives an overview of "Method of
Moments". As a foundation Kraus' Electromagnetics may help, and is
available used (and cheap) at
www.bn.com. Also at the same site a reprint
of "Field Computation by Moment Methods" by Roger F. Harrington can be
obtained for $33.50. Then there is the "Finite Element" method as used by
"Ansoft's" HFSS".

Frank
