So the other day I was walking in the park and a man came up to me and said: "Hey there I believe you dropped your set it off in a store and steal as much as you can Wallet." I checked and sure enough it was my wallet. I took it, gave him 5 dollars, and thanked him then walked off.

Quick question..

I thought shielding didn't work against an EMP..

The link http://www.totse.com/en/bad_ideas/ka...om/161699.html states otherwise though..?

Of course shielding works. Ever heard of a Faraday Cage?

Such a high frequency pulse can pass through faraday cages used to ground electromagnetic energy from lightening. However, even if the cages were effective they would still be easily bypassed since any wires running from the devices within them would act as antennae and conduct the high transient voltage. There is also a so called 'late-time EMP effect.' This refers to the observations of EMPs creating localized magnetic fields within electrical systems they pass through that soon collapse sending huge surges through power and telecommunication infrastructure. This sparks a chain reaction in which all devices attached to these lines will be rendered useless by the massive surge.

30 KHz is hardly what I'd call a "high-frequency" burst.

Microwaves, for example, use 2.455 GHz - and they're shielded quite well. I dare say that my kidneys are not boiled yet.

Oh, as an addendum: Those guys don't even get the history right. They did not even wonder why the Faraday cage was named "Faraday"...
From their site:
Quote:
That is when they discovered the "rays" that were harmful, as well as the phase transformations. In the course of their work, one of the scientists discovered that simply covering an object with a grounded copper mesh would stop virtually all electromagnetic radiation, whether proton or neutron. Obviously, they had to protect their monitoring equipment! Thus was born the "Faraday cage."
Now, here's the actual, factual truth from wikipedia:
Quote:
The Faraday cage is an electrical apparatus designed to prevent the passage of electromagnetic waves, either containing them in or excluding them from its interior space. It is named for physicist Michael Faraday, who built the first one in 1836.
And I won't even get into their mixing up of terms like: "electromagnetic radiation, whether proton or neutron"

You wanna see a high-frequency burst? Come to my place after I eat 12 tacos and a big bowl of stewed prunes...

What kind of frequency do cellphones work on? Have you tried putting one in an (unactive, obviously ) microwave and calling it?

GSM cell phones use frequencies within four different frequency bands:

*850 MHz (824.2 - 848.8 MHz Tx; 869.2 - 893.8 MHz Rx)
*900 MHz (880-2 - 914.8 MHz Tx; 925.2 - 959.8 MHz Rx)
*1800 MHz (1710.2 - 1784.8 MHz Tx; 1805.2 - 1879.8 MHz Rx)
*1900 MHz (1850.2 - 1909.8 MHz Tx; 1930.2 - 1989.8 MHz Rx)

Thus it stands to reason that the shielding of microwaves should also work for the lower frequencies (which are generated at a much lower power level - remember that a microwave usually consumes several hundred Watts).

I can't test it, though, as our house contains some steel-concrete and thusly is already quite "EMP-proof"

You're absolutely correct on all of the above..
still I do distinctively recall having read or seen that simple farraday cages aren't enough to provide shielding, not even when grounded. obviously I'd have to delve into in much deeper.. Unfortunately I'm tied into some other time consuming stuff atm so I'll bump this thread again as soon as I find the time..

No, there is no shielding aginst me Magnetic field, if it is strong enough, it can't be absorbed with something like that, range dissipation is only thing that helps If you'd realy like to create EMP, make transistor without secundar. Bigger piece of iron enveloped with conducting wires if rough example of magnet. Just don't do it near your computer!
