What I'd like to know is if this is relying on drones (either multirotor or fixed wings) having carbon fiber or plastic bodies as opposed to enclosed metal.

- foobarian 10y agoCarbon fiber is conductive.
- Florin_Andrei 10y agoIt's a lot more effective to kill the circuits. Sure, carbon fiber is conductive, but the energy involved to fry the CF booms is orders of magnitude that required to just zap the flight controller.
- MertsA 10y agoI think he's suggesting that the carbon fiber is much more RF transparent than metal.
- scld 10y agoYeah, didn't really have time to flesh this out, especially if it's carbon filler material vs. continuous. I haven't worked enough with CF to know what its shielding effectiveness is but I imagine given the size of that Phaser that this thing will be trying to blast through some stuff.
- Florin_Andrei 10y agoOh, I see. Penetration depth depends on resistivity. A superconductor has a penetration depth of zero. A real material, it's non-zero. Carbon fiber is conductive, but not as good as a metal. Therefore I would expect penetration depth to be quite a bit bigger with CF. So, perhaps it's not a good idea to rely solely on CF for shielding. https://en.wikipedia.org/wiki/Penetration_depth https://en.wikipedia.org/wiki/Penetration_depth
