Some Questions
What is:
(1) the intended field (E or H?) and wave impedances range;
(2) its dynamic range (intensity/strength/density);

You may be able to sense up to a few MHz using normal probes without
having to go into laser interferometry with a fiber optics. There are
some work on spherical probes by Miles Upton a few years back.
