The US government, in its undying lust to find new and exciting ways to keep its citizens under wraps has developed the Active Denial System. This device works by directing electromagnetic radiation at a frequency of 95 GHz toward the subjects. The waves excite water molecules in the epidermis to around 55 C (130 degrees Fahrenheit), causing an intensely painful burning sensation.
While the skin is not actually burned, the sensation is very painful, and can only be tolerated for a few seconds. The focused beam can be directed at targets at a range of just under half a kilometer, or 500 yards, making it a great tool to use on nonviolent protesters or just about anyone who would speak out against the all-mighty government.
I, in my undying lust to find new and exciting ways prevent the police state from exercising its Orwellian control over the public, find myself delighted to tell you how to defeat this system. As anyone who has taken a physics class can tell you, electromagnetic radiation can not penetrate a conductor. This is how a microwave works… Inside your nukerator is all kinds of EM radiation, but the little metal mesh on the front of the door keeps it inside and prevents you from cooking yourself.
Knowing this, we can come up with a host of ways to defeat the Active Denial System. You could create a wire-mesh shield, and bring it with you to your protest. This would work fine, but the mesh would have to be VERY tight, as the ADS delivers a much higher frequency wavelength at 95GHz than the measly 2450 MHz (a wavelength of 12.24 cm) that your microwave uses. You could line your jacket and pants with tin foil – remembering of course that you must also protect your face and neck.
You get the idea, simply put a mesh or sheet of conductive material between yourself and the ADS, and you win… Have fun storming the castle!
