Doesn't this also mean that they would not be able to receive comms?

  If you folded the entire thing then it could mean that. But you want to shield the parts which do not directly need to receive rf signals, like the mainboard.

  Comms can also be laser, and the drones can be pre-programmed and self guiding. Though in either case, you can still always dazzle either the sensors or the comms (MEMS sensors used for inertial guidance are vulnerable to ultrasound IIRC). And I’m sure the military either have or are developing an anti-drone-drone.

    Well the military has AESA radars that can be programmed to act as a microwave laser so there’s that. A Faraday cage won’t be of much help if it’s literally cooked.

      Um. What do you think the grid of wires in the window of your microwave is for? Its a faraday cage to keep you from being cooked.

        If you pump enough power at the shielding, a) some of it will get through and b) the shielding itself will get very hot from induced eddy currents.

          > pump enough power Problem is you’re fighting path loss which is exponential with distance, whereas the power of your emitter is scaling linearly.

              You’re right of course.

  Not necessarily. You can transmit signals between completely isolated circuits with an optocoupler for example.
