There is such a thing. You can even assemble one in your garage.
W/o going into details, some machined copper and explosives can give you a directed EMP weapon for several hundred feet that can disable unprotected equipment. Needless to say, a more advanced formal effort can be extrapolated, since in my experience even SAIC contracts I worked on were a couple generations ahead of commercial products (this was in wireless telcom switching in the 90's), and the spooks there told me similar stories. some of these I still find difficult to believe w/o some further proof, but the bottom line is when you have unlimited resources, and hire more scientists than anyone in the world, your only limitation is physics.
In the case of an EMP attack, there are inevitable leakage paths across the radio spectrum, reports of which can still be researched, since they would effect nearby radios at that moment, and possibly several pulses, which would indicate professional equipment not garage-type. It would be interesting to raise that issue among ham operators in the higher frequencies, operating near the airport. |
