There are some far field technologies but they have limited range and
tend to be detrimental to humans or other furry things that wander into
the beam.
I worked for a company that made dielectric heaters for the plastics
industry. Our quick and dirty test for a leaky RF cavity consisted of a
fluorescent tube taped to a broomstick. Transmitting enough power to
make it light up was not a good thing.
Sterility guaranteed!
