Physics question

Whoa Nelly. Hang on a sec. I have a fundamental physics question. In
my previous post I was using the inverse square law as a measure of
power lost in transmission, but is it more correct to say that it is
power lost per given area.

The inference from the last question, is that all of the power can
be captured by having a rectenna that, in the case of the 180 degree
separation, is the inverse of 9%, namely 11.1 times larger than the
transmitter. And in the case of the 120 degree separation, the
inverse of 24%, namely 4.166 times larger than the area of the
transmitter?

If the above is correct, then my doubts about the feasability of
space power sharing may have to be reconsidered. It is my
understanding that rectennas are constructed of less expensive
components than the SPS. Maybe it could work?
