Radiated E-Field in volts/meter (or near field) is a verifiable and
measurable quantity. Why do linemwn wear those suits when they're
working near 400kv transmission lines? There are also endless
guidelines for E-Field exposure limits both in residential, indistrial
and commercial environments posted by hydro companies for decades now.
What are the guidelines for? You get close enough to a large E-Field
and you'll get more than just thermal effects. Microwaves are also a
large source of directed E-Field which is from time to time envisioned
as a source for wireless power transmission, again more than thermal
effects. The power receiving apparatus is often called a rectenna.
Try holding a pop can up in front of a powerfull radar horn while the
radar is operating. Use a long stick for the can. Must be something
blowing that can apart. High power broad band micowave sources using
sophisticated high power spark discharge devices such as marx
generators integrated into a tuned transmission line are being tested
for possible weaponization. Check out some of the US navel test ranges
or use a search engine for the term "transient electromagnetic
device". A number of home brew TED's are also on the net as well as
coin and can crushers. A similar technique is used in medicine to
produce powerfull, focused and directed acoustic shock waves, see
"lithotripter". All have one thing in common, they use a very
powerfull and high speed spark discharge. The first experiments in the
production of milli-meter wave radiation also used a spark discharge
system more than a hundred years ago.
