"If they try and deflect beams then we will kill them because we know what their intentions are"
Welcome To The House Of Pain (Ray)
It's going to be a hard one to beat. Other security systems may flood the place with tear gas (which is hard to get out of the furniture afterwards, and can be beaten by intruders wearing gas masks) or set off 150-decibel screaming sirens (which are no match for earplugs). But there are no effective countermeasures to Active Denial.

<snip>
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!

Hello,
I would like to point out that RF waves (including) Voice To Skull microwaves can be ‘conducted’ by metal foil just like any wire.
Penetration (as you say) can be stopped (if) the foil conducts the waves away (from your body) to another point such as earth ground.
Merely walking around with foil isn’t enough. The foil must be electrically capable of ‘conducting’ the offending waves away from you.Done correctly, metal foil can be a very effective defense against Voice to Skull. But it takes a knowledgeable person (such as a Ham Radio operator) to understand the requirements of good shielding. It can be done with the right technique.
I have a background in Electronics Engineering. Best wishes to all….

My recent pieces on the Active Denial System (ADS) or ‘pain beam’ sparks discussions here and elsewhere on the web. One of the most common challenges to the device is that the beam of short-wavelength microwaves could easily be blocked with tinfoil.
It’s not that easy.
Captain Jay Delarosa, spokesman for the Joint Non-Lethal Weapons Directorate told me:
"We have conducted extensive testing and have determined that most readily available materials are not effective as countermeasures against the ADS.“
Few people appreciate the reasons behind this, and even John Pike’s otherwise excellent GlobalSecurity site claims:
<snip>
…actual tests show that the beams penetrate even minute openings or cracks, for example, and sometimes appear almost to wrap around corners to affect fingers and feet of those trying to hide behind or hold up protective devices.
"The radio frequency is hard to block," Booen says. "Some of the people tested against tried to hide by laying down behind some concrete traffic barriers and the beam went underneath {where there was uneven contact with the ground}."
What about that tinfoil? It will have to cover every square inch and any rips or tears will make it useless. Joints may be tricky; if you flex foil too many times holes start appearing. For vision you will need a metal mesh visor, like the kind they use on microwave oven doors. The problem is, the size of the mesh depends on the wavelength of the radiation - so short-wavelength ADS beam requires something much finer than normal microwave mesh. You also need to think about the effect on your breathing, body temperature and communication.

“If an individual makes extensive efforts to counter the effect of a non-lethal system, then they are likely showing hostile intent and an escalation of force may be warranted based on existing rules of engagement.”
"If they try and deflect beams then we will kill them because we know what their intentions are"

The Pulsed Energy Projectile (PEP), which I described in New Scientist (subscribers only) is a non-lethal weapon which fires an extremely short laser pulse, producing a plasma flash-bang at the target. This could be deployed on the same platform as the ADS, using the same power source.
“Many of the countermeasures that can be envisioned against the ADS” could be nullified by the PEP by “ablation of the defense” according to a Navy study on the effects of plasmas. Such a laser could chew through a layer of foil with a few pulses.

<snip>
Fine, but how do you thwart it? The best protection is distance, just don't
be the target! However, if one wishes to engage in a demonstration and be
protected from this device, the best protection would be your own
electromagnetic shielding or "Faraday cage." If you are within a conducting
mesh (a Faraday cage), where the mesh openings are small with respect to
the incident radiation,
and with a ground wire that leads intercepted
electromagnetic energy away from you, then you are safe. This remedy is not
likely to be convenient, but then, perhaps creative talents can find
effective refinements of this concept. A suit of armor with chains trailing
from your ankles to leak currents into the ground may not be ideal
protection. However, plastic shields with embedded meshing, even aluminum
foil or aluminized mylar (shiny garbage bags?), behind which individuals
could stand (huddle?, crouch?) might allow people to thwart the intent of
the device. Once people understand the physics being used against them,
they may be able to to fashion materials readily available to them into
effective countermeasures; this requires some planning.
Given that a popular assembly might plan to protect itself from a heat ray
crowd dispersal device by arming itself with body-length protective
shields, and Faraday suits,
could they also use their shields as reflectors
and "phase array" them to return the beam back to its source? This calls to
mind the story of Archimedes' heat ray, during the siege of Syracuse during
214-212 BC. The Roman historian Lucan wrote that during the siege of the
city by Rome, Archimedes had the defenders of Syracuse align their bronze
and copper shields, which had been highly polished, so as to reflect
sunlight on the attacking ships, which burst into flame. Modern experiments
aimed at duplicating this effect show that the effect is most likely with
many reflectors, ideal weather conditions and orientation of objects with
respect to the sun, and with highly combustible materials and coatings
(e.g., wood varnishes) at the targets. For a phalanx of our popular action
Faraday Knights, the equivalent might be using the concave (perhaps
parabolic) sides of their protective and reflective shields (without
grounding wires, and with insulated handles for their users) to redirect
the incident microwave radiation back to its source, or thereabouts.
Of course, it bears realizing that any successful countermeasures to crowd dispersal ray devices are guaranteed to move the authorities to escalate to more lethal measures of control. For a continuing revolution, this is simply another level of planning. END
