    the article mentioned destroying your electronics so I assume it's permanent. Not very familiar with emp's though.

    emps fry any electronics guys, if it is plugged and or powered on even with say a battery on your pcs motherboard, your stuff is out. great way to take out an enemy without destroying anything!!!

    Generally speaking, the net result of Electro-Magnetic Pulse and Flux Compression Generators, is a broadband high powered RF signal, that induces voltage into power lines and circuitry sufficient to interrupt or damage that electronic device. The net-effect of these is felt more strongly where you have long wires that run power or data between devices as more voltage will accumulate in them and do more damage to connected devices.

    The other important factor is distance from the emission source... as the inverse square law is important in delivered energy.

    Interestingly if you read this article: Boeing zaps PCs using CHAMP missile microwave attacks ? The Register

    There's a video, and the author makes note that one PC in the video (lower right corner) doesn't seem to go out right away, and seems to reboot itself. Also, the lights stay on. My bet is, this is much ado about nothing, and this system would likely only effect delicate timing sensitive electronics systems (computers, data networks, and electronic measurement and control SCADA systems). It would likely have little to no effect on electrical motors, vehicles, batteries, etc.

    Another factor with this weapon system is not just that it has an EMP-like effect, but that it's focused and therefore aimable. Rather than destroy the entire infrastructure of a city or region with an EMP there will be the ability to destroy just the systems that you want to, such as radars, air defense, communications, etc.

    Imagine a drone cruising an area zapping specific targets just like they do with explosives now.

    I would be willing to bet money this thing would have zero effect on the radar equipment itself... The radars are capable of handling more power than this thing puts out (anything that will cook you if you stand next to it for more than 10 minutes).

    Maybe the radar receiver could withstand the power, but I still seriously doubt that. Receivers only pick up a minute fraction of the power sent out from the transmitter and then amplify it dramatically. Most of the transmitted radar pulse is lost in space.

    However, the equipment running the system, the computers, would definitely take a hit. The computers, the monitors, the IFF/SIF, etc would all be toast. Without that, the transmitter is pretty much useless. Perhaps if they were still running tube tech radars the computers would be more hardened, but not a modern digital system.

    What little I know about chemical-explosive EMP's is that their pulse is longer but lower intensity than a nuke. The result is that some shielding can saturate and let the rf energy through if it's only designed for a short pulse.

    AMProducts is right on: These things work by cramming flux lines in a small space for a short time. Their earliest incarnation was nothing more than a coil-wrapped magnet that was blown up with a platter charge.
