In principle it is quite easy, but not cheap. Not particularly safe
either. Do you actually want to rig something up for the mid-term, or
do you just want to do a mock-up?
For efficient narrow beam transmission / reception you would use an
accurate parabolic reflector at both ends but they would need to be at
least ten or twenty times the wavelength in diameter. I?d have to do
the calculations to give you a definite on this But that?s still the
easy bit. Microwave transmitters are especially difficult and involve
very specialised and critical electronics -- and as I said, lots of
bucks. Microwave cooker magnetrons are cheap but you *really* don?t
want to mess with these -- waveguides, let alone the radiation and
voltage hazards. Then there is the received signal which has to be
efficiently converted to electrical (?) power. Several ways to do this
but again it?s not the sort of thing which one can just lash up.
So if you just want a mock-up, fine. Several people (other than I) who
can advise, but a readily built working system is not really viable
(or legal) I?m afraid.
What thoughts then?
