The reason for converting energy to microwaves is because it impervious to weather condition and water in the upper atmosphere.
In its broad-beam form, microwaves become safe for birds and insects to fly through. Microwaves also have an efficiency advantage.
Typically power has to be converted twice: first from DC power to microwaves aboard the satellite, then back to DC again on the ground.
In lab conditions, researchers have achieved about 80%efficiency in this kind of power conversion, which is far better than with other forms of power.

Whereas a conventional microwave radar system uses a moving dish antenna to collect microwaves reflecting off a moving object
the Duke system uses a stationary metamaterial aperture, a strip that guides microwaves to a single sensor.
But here, the source sequentially sends out microwaves of different wavelengths. The returning waves are collected then by the metamaterial aperture.
As microwaves travel down the metamaterial strip, they interact with patterns etched along its surface.
Current atomic clocks are based on the microwave signals emitted by electrons inside an atom as they move from one energy level to another.
