Transmitting high power through a phased array is non-trivial. Most array
elements are fairly low power amplifiers. The high power is from the correctly
phased sum of all the elements.

IF you go through a resonance. You need a lot of power to do damage otherwise.

Their frequency goes all over the place.. like +/- 10 to 20 MHz.

There is a big difference between building up strong E fields in a resonant
cavity and at a distance in free space.
