“It’s pretty much the same principle as a microwave oven,” he told The Register. “The flaws allow us to ramp up the frequency.”
Shirly "ramp up the power" ? You might find a software command to alter the frequency, but it may not do much due to real world physics.
A microwave oven uses a cavity magnetron, so called because of resonant cavities, which give effectively a fixed frequency.
At microwave freqs the dimensions of the waveguide usually optimsed fot the band restrict the frequency range that can be passed without significant loss.
It`s about an octave up to I think C band and reducing in higher bands Wideband microwave power amplifiers struggle to achieve the w/guide liimits at full power
No chance of ramping up!
For satcomms, usually Tx (/+Rx ) antennae are not huge and are pretty directional but not tremendously high powered due to the modulation techniques and using them as a steered death ray is going to take quite a long exposure. There are telltales such as signal loss, safety mandated non networked connections for transmit status ,dish positioner etc that will show.
Years ago having a return signal drop on a Tv Sat flyaway ( which is hundreds of watts @ Ku) looked out of the tent and had to chase a bystander out of the beam having walked through the safety fence labelled "keep out radiation hazard". plus the yellow picture signs.
Having explained that it was "Like walking into a microwave" ( no it`s not) just to impress the hazard........
"so if I put a sausage in there it would cook?"
"no but it would possibly go blind and not be able to father children".
