Building an electromagnetic deflector shield - how??

[Captain_Nick]

Loing time no see guys

(carn the pies!)

I want to build a shield to counteract the army's latest weapon - the 'non lethal' (except when the operator is drunk or pmsing) heat ray gun.

It works by shooting a beam of intense electromagnetic radiation at people, causing their skin to heat up to 45-50 degrees

My research is showing that a crazy person's tinfoil outfit will actually protect them from most of the radiation! But that is not classy enough and you can't cover your entire body with foil anyway, nor can you protect the women and children that the military types will want to hurt as much as possible.

And besides .. the em shields used on star trek are so much cooler than tin foil hats!!

The trouble is, I don't understand enough physics to know whether it is even possible to build a shield generator, or how it is supposed to work.

We must have some brilliant minds on this forum. I can provide hardware and capital, but I need a brains trust to help me.

Will you want to be running from the enemy while operating this shield or will you be stationary?

Countermeasures beget further measures in an escalating arms race. I suspect your funds would dry up before a government's. Why are you proposing to take on the Army anyway? If this is the Australian Army we're talking about, why are they adopting non-lethal weaponry?

It's important to be able to defend yourself from aggressors. I agree that an arms race is a waste of money and sheer idiocy, but the alternative - submission - is unacceptable

 

[Asbo Zaprudder]

Who's asking you to submit? Anyway, I suspect that the effects of this radiation (which I assume is terahertz or submillimeter based) would also be much diminished by a fine mist of water droplets sprayed in the direction of the emitter.

AWESOME

'Shield' generation just got practical

I believe the active denial system actually uses a frequency of 95 gigahertz (3.2mm wavelength) but water droplets would still be a good defence if you weren't already incapacitated.

You should totally rig up the shield generator to the back of your push bike, make it pedal powered. So you can flee and defend simultaneously.

Actually, I think a crimson force field is what you're looking for.

Don’t wanna hurt no kangaroos.

Would the radiation cause the water droplets to heat up?

Yes as they'd absorb the radiation rather than your skin. The weapon works by exciting rotational modes of vibration in water and fat molecules. You'd need to replenish the "shield" to prevent it disappearing.

And not stand in it while it is shielding
