A recent issue of Aviation Week had some articles on
high-power-microwave weapons. There's a blurred photo of a
BAE-developed switching gadget that looks like a coffee-stirrer-sized
slab of white ceramic with some dark strips deposited on top. The
strips may be something like GaAs or possibly amorphous diamond. It's
the heart of a 4x4 inch "tile" emitter.

Each tile apparently has a dc/dc converter and a storage capacitor.
The cap is charged to 9KV and the strip thing is blasted by a
diode-pumped yag laser. It switches on in picoseconds, dumping 30,000
amps (270 megawatts) into a wideband antenna built into the surface of
the tile. A plane can be covered with these to form an
electronically-steered transmit antenna capable of beam-forming
something like 10 GW of impulse RF, with much higher powers expected
in a few years. This will illuminate a stealth aircraft 100 miles
away, or fry the electronics of an enemy plane or incoming missile.
Navy versions could hit terawatts, enough to shut down everything on
an enemy ship. There's talk of using these against roadside munitions,
too.

google has a lot of hits.

I'd like one on the front and back of my car!

Man,I really miss having a subscription to AvWeek.

What..shielded electronics don't work???
If that screen on my microwave oven door doesn't cook me at 1kW...,
I'm wondering how a microwave burst (from a distant) is going to fry
shielded electronics..

Sure, but whole generations of planes and missiles and avionics would
be neutralized by this. That includes all those surplus shoulder-fired
heat-seeking missiles. And roadside, cell-phone or RF-triggered bombs
would be hard to make. Wanna capture a remote terrorist camp? First
pass over and zap all the communications and all the vehicles.

Imagine the next step: put these gadgets into cruise missiles or
remote-piloted drones; fly them over enemy territory and take out
command centers, communications, airfields, power plants, almost
anything. The sheer volume of shielding and testing for defense would
be impossible to do any time soon. Such a drone could defend itself
with the same system, so basically shuts things down until it runs out
of fuel.

Not easy to stop the old diesel engine.
Low budget low tech guerillas will not even notice.
And their cell phones can no longer be tracked.
Looks like shooting yourself in the foot if you are a high tech war maker.

10 GW? Terawatts?

It's pretty hard to get hundreds of db of attenuation in shielding.

So how do you protect your own on-board electronics?

John,
a good first of Aprils. There are persistent plans
of whatever forces to apply microwave and laser
weapons to no avail yet. Never mind if they do not
work, at least they are good to get some government
money.

what do you expect a reflector to do?
HPM is not a laser beam,it's an RF pulse.

D from BC

"shielding" is measured in DB of attenuation,it's not a total block of the
pulse.If the pulse is powerful enough,it will generate levels of energy
high enough to harm the "shielded" electronics.

didn't he say it was a beam of HPM?
then the side lobes would be very far down in power.

I have no idea as to the attenuation of say 2Ghz trying to get through
some thin ferrous (of better) shielding.
Also, isn't a good portion of microwave radiation reflected off metal
shielding?

yeah, I didn't specify RF or Light did I ?
So how do you arrive at light since we are
talking RF ?
Last time I knew, RF can be reflected .

Well, yeah, I guess zap guns (or whatever you want to call them -
Blasters? ;-) ) have been pretty much inevitable since they discovered
radio. :)

And I'm kinda disappointed - when you started with "...looks like a
coffee-stirrer-sized slab of white ceramic with some dark strips
deposited on top. The strips may be something like GaAs or possibly
amorphous diamond. ..." I was thinking "hand-phaser sized!", but it
turns out it has to be bigger than a Howitzer. Sigh. ;-)

Wouldn't it be a lot less bloody if somebody came up with something that
works like "phasers on stun" - you fire your weapon at the foe, and he
goes to sleep for some convenient time, usually until right after the next
commercial. ;-)

Then, you take your captives, who are now prisoners of war - they were
combatants, right? Anyway, you take these guys and put them in a bed
in a nice hotel room and surround him with hookers, and convince him
that he's in heaven with the 72 virgins.

Next thing you know, World Peace I! ;-)

And it'd be cheaper than what we're spending now!

It just hit me - the amount of power this thing would need would be
astronomical - you might as well use a little nuke, not that there's
anything right with that. =:-O
