Radiofrequency Weapons 377
BWJones writes "Global security is running a fairly detailed and interesting story on E-bombs (not email bombs, rather electronic microwave weapons) taken from the IEEE Spectrum Online.
We have long known (since the 1940's) about the effects that high energy weapons can have on electronic components from nuclear blasts, but this class of weapons is designed to exclusively attack electronic infrastructure. "

The result is to "compress" the current, and thus the Magnetic field around the charged coil.
the result is to eject a very intense Magnetic field in the given direction.

And explosives in the middle. The middle has no bfield, becouse the 2 coils cancel each other. but between them, a lot of enery is stored in a b-field.
Not the explosive is started at one end, burning towards the other end. It presses both coils against each other, squeezing the field into the rest of the gap. Once the deflegration hits the end of the coils, the field has nowhere to go and the whole stored energy is released in a single electromagnetic blast.

Re:Neutron Bombs are better (Score:5, Informative)
You've (both) missed the point of "neutron bombs" (a.k.a. enhanced radiation weapons).
The goal was never to drop the things on cities to "kill the people and save the buildings". The lethal radius from the burst of neutrons is on the same order of magnitude of the lethal blast radius, typically a few hundred meters. Wrong weapon for wiping out a city. (Which is fine, because wiping out cities isn't what they were designed for.)
Where neutron bombs would have had great effect would have been in wiping out large columns of tanks, presumably Russian, clustered together as they were funnelled through places like the Fulda Gap in an invasion of Eastern Europe.
In those scenarios, NATO forces didn't have sufficient conventional weapons to deliver on the tanks to make a difference. And because tanks are pretty blast-resistant things (crunchy shell, soft center), the only way to wipe them out en masse would have been to nuke them.
With 100,000 tanks bearing down on you, you've got two options:
(0) Surrender. Not an option.
(0) Fight conventionally, die anyway, because you're outnumbered and outgunned. Not an option.
(1) Blow 'em up. Carpet-bomb the countryside with 20-megaton blasts spaced 2-3 kilometers apart, because that's the kind of blast power it's going to take to crack the hard crunchy steel shells. Then discover your own troops are up to their armpits in icky long-term fallout, to say nothing of the fact that you've killed 20-30% of the civilian population living downwind, and that whoever wins the war can forget about farming for, oh, I dunno, the next decade or two.
(2) Fry 'em. Drop kiloton-yielding neutron bombs over the same area. Low explosive yield, low collateral damage, low fallout, just instant bursts of neutrons that rip through the crunchy steel shell and (in the space of minutes) incapacitate and kill the soft juicy tank crews at the center.
Once the burst of neutrons is over - literally a period of milliseconds - the mess is largely gone. (Yes, you have some neutron-activated substances near the blast site, but we're not talking huge quantities of fission daughter products, which are the real bad news to the survivors of a nuclear conflict).
Meantime, the Russian advance is stuck dead (literally :) in a traffic jam of tank-shaped coffins. Casualties in the area are pretty severe, but the affected area is pretty small. Most of the casualties are military, not civilian. Your troops can move through the bombarded area in relatively short order, and whoever wins the war can feed the surviving population, because you haven't blanketed half the arable land in Europe with long-term fallout.
None of the options in a nuclear conflict are that great. But enhanced radiation weapons were actually one of the best options available to commanders of either side during the Cold War. It's a shame that the FUD surrounding them went so out of hand. (Then again, maybe not. Deterrence turned out to be the best nuclear policy option of them all :)
