Just stumbled on this item, indicating that youze guyz might be defficient
in more areas and I should revise my treatment of some of your previous
answers.

from Johnson - Jasik, Antenna Engineering Handbook, 2nd Ed., p. 5-21:

The product of Xerox....

So this idea goes into "to do" pile to be researched or explored.

Hi Yuri,

Just so you get to that first instead of 'splainin' it.

You might visit the library for a copy of R.W.P. King's "Antennas in
Matter," of which I have a copy. You've gotten the short answer from
us, the long answer doesn't change the outcome.

NEC-4 is a lot less expensive than it used to be, and it can be used to
analyze antennas immersed in water, dirt, or another medium besides air.

As for the complexity of calculating the near field, you can struggle
through the math as suggested by Jasik, or you can let EZNEC do it for
you and get the answer in seconds. EZNEC makes no simplifying
assumptions about the loop size.

-Proud to add the title of Yuri "defficient" to my many others. Not
quite the level of being a Reg's Old Wife, but a credit nonetheless.
Thanks, Yuri!
