    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..

    Ok, how about reflectors on enemy craft, vehicles?

    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,

    google has a lot of hits.

  6. Yep, won't knock out a diesel engine

  7. 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?

    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

    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.

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

    Jim Yanik Guest

    "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.
  13. Jim Yanik

    Jim Yanik Guest

    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

    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 .

    The F-22 is already flying with some of this technology.

    google it, today or tomorrow.

  18. 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. ;-)

  19. 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!

  20. 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
