High-power microwave optics for flexible power transmission systems [PDF]

open access: yes, 1980
A large concave microwave mirror near the transmitter can magnify the apparent size of the Earth as seen from a phased array, and vice versa, permitting a small phased array to be coupled to a small rectenna while preserving the transmission efficiency ...
