Just wondering if there is any potential in this or if anything was
written up in the antenna books pro or con.

I think you're on your own. The path is clear for you to be the first to
make great discoveries! Just be sure to take a little time off along the
way to do make those coil measurements.

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 brevity of this review requires omission of many interesting topics
concerning loop antennas. In recent years, there has been considerable study
of loop antennas in close proximity to or embedded in material media such as
the ocean, the earth, or a plasma. The electrical characteristics of loops
in these instances can be quite different from those of loops in unbounded
free space, as described in this review. The major applications of this work
are in the areas of subsurface communication and detection (geophysical
prospecting).
The loop antenna near a planar interface separating two semi-infinite
material regions, such as the air and the earth, has been investigated
extensively. When the loop is electrically small, it can be approximated by
an elementary magnetic dipole, and the electromagnetic field away from the
loop can be determined from the classical analysis of Sommerfeld. If the
field near the electrically small loop is required, the approximation by a
magnetic dipole may no longer be adequate, and a loop with a finite radius
and a uniform current must be considered. For the electrically large loop
near a planar interface, an analysis that allows a nonuniform current in the
loop, such as the Fourier-series analysis for the circular loop, must be
used."

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