Directed radio frequency (RF) energy cannot be easily disrupted by adding more RF energy from a "blocker" type device.
You can shield against RF but the shield must be a near perfectly conducting box otherwise it will not be very effective.
If you know the frequency of the RF, in theory, one could make a dielectric phase shifter to either absorb or reflect the RF energy, but will not be an easy task.
In summary, NO, RF energy is difficult to block.

Like a device that could cripple people that try to use EM weapons? I know there are things like cell phone blockers, but maybe something stronger that would cause an attacker to have a stroke or something if they tried to use EM? Certainly that would stop all of this (for right now), and we wouldnt have to shut off ALL of the power grid (which seems to be the only solution currently).
