Thank you.There are three components of a Nuclear EMP blast, E1, E2, and E3 which are of different wavelengths and durations, and they affect different types of circuits and components. Shielding designed for one component may be useless against the others. Too much to try to explain here but just do some reading up on them.
A Faraday cage operates because an external electrical field causes the electric charges within the cage's conducting material to be distributed so that they cancel the field's effect in the cage's interior.
Ask any ham about proper bonding and grounding...Bingo! To work correctly you want a clean metal surface on the inside of the cage. Double wrap your electronics in ESDS bags. To function correctly the cage must have a tight fitting lid and a good ground connection, copper strap is best, then braid. That single strand of 16ga green wire will not get the job done.
There is a lot of misconceptions about what a Faraday Cage is and how it works. A Faraday Cage doesn't need to be insulated on the inside to behave as a Faraday Cage. LOOK IT UP! But that's not the only kind of shielding you need for an EMP.
yeah thats what I read, over here in the UK we dont make them and they arent kept "on the shelf" so have to be ordered, made and shipped from overseas, each one takes several months so doing the whole system could take anything up to 2 years, thats even if they had the engineers to do it.An EMP attack would take out all the power transformers. Right now there is a one year lead time for those big transformers. All silicon junction devices would be destroyed. An EMP attack would take any nation back to 1880's real fast. Life as we know it would vanish.
The big transformers, have to be moved via rail.An EMP attack would take out all the power transformers. Right now there is a one year lead time for those big transformers.

they certainly arent over here, ever here of Doctor Beeching? he closed a lot of the branch lines back in the 1960s, there is only one rail line down through my county and into the next and that is on the south coast nowhere near my location.The big transformers, have to be moved via rail.
And as I understand it, some of those rail lines are no longer there.
Although I agree to some extent with that, I think there is a misconception here. Michael Faraday himself acknowledged they have limitations by design, and while some signals may be blocked, others can still pass. Too many people think it must block 100% of everything to earn the name Faraday cage, this is not true. If it were, the device would be theoretical only. For example, slow-moving magnetic fields can get inside something like a sealed propane tank. I was pointing out these design issues so that people have an understanding of what they expect their "metal container" to accomplish. Obviously, if one does a crappy job, they can just call it Faraday Screening. Many scholars and universities use the term Faraday Cage for a variety of enclosures short of theoretical perfection. Sufficient broadband attenuation to achieve a high probability of protecting what's inside is the only criteria I use for describing something as a Faraday Cage. Theoretical perfection is for people with book smarts, a good calculator and zero hands-on experience!Then by definition, it is NOT a Faraday Cage!
