Re: What you need to know about EMP weapons
#152I'm not sure about most of this. The great majority of the articles and stories about this I've read trace back to layman speculation and disaster porn fiction written by people who have never claimed to actually be informed about how these things work. There's damn little stuff out there that traces back to actual experiments with real hardware. Probably most of the serious experiments are by various militaries and…
There's plenty of unclassified info available. Start here.[1] This is an overview document from Defense Acquisition University, a unit of DoD. It's a painful PowerPoint. You have to plow through a lot of really boring military documents to get the details.
EMP doesn't address small devices much. Small devices with no wires connected are not very vulnerable, because the energy is mostly at somewhat longer wavelengths, meters or tens of meters. Worry about cell towers, not cell phones.
Other than the power grid people, the civilian sector doesn't look at EMP hardening much any more.

Yeah, what I've learned from films like "Threads" and "The Day After" is that you very much want to die in the first 20ms of a nuclear war. Don't dig a hole to hide in, put your lawn chair on the roof and hope you're close enough to ground zero to get a peaceful and dignified end.
nuclear war is a lot more survivable than people make it out to be. if you can get your hands on enough clean water to hide in a basement for a week you'll basically be ok

Am I missing something? Should I be worried?

The Ukraine conflict has frequently raised nuclear fears mostly due to Russian nuclear sabre rattling. But this has been happening since 2022 and it’s hard to see anything going hot anytime soon

Why not try a large Stanley cup? Double layered, top seals shut, pretty easy to get a hold of.
Your microwave oven is pretty good at attenuating 2.45 GHz signals.
That's a notch filter, though. Attenuation outside of whatever stopband the microwave door was designed for won't be nearly as good.

Let me tell you something from first hand field experience with faraday cages... They attenuate signals, they do not block them. The common verbiage is to say "faraday cages block EM radiation", so people naturally assume that it blocks EM radiation. But I learned the hard way while doing compliance testing that no, they do not block EM radiation, they just weaken it (and it's highly frequency dependent on top of tha…
Well, I am not sure how you expect redneck prepper types to pick up on enough RF theory to manufacture homemade metamaterials.
We aren't all rednecks. Or maybe we kind of are but some of us have engineering degrees.

The problem with this strategy is that the "instant death zone" is much much smaller than the "3rd degree burns over 100% of your body" zone.
I don't share your fatalism, but I can't criticize it. It is an understandable position. With that said, if your desire is truly to remove yourself from existence in the aftermath of such an event it is better to have some plan to do so already laid in. The majority of immediate casualties will not be deaths, you are very likely to regret relying on the weapons.
That would also grant you the chance to reconsider whether the resulting world is actually not worth living it -- or at very least to confirm that it is in fact so bleak.

I happen to be from the same town as this guy. He is well known for building his own ramjet-powered cruise missile.
I don't know about recently but he was actively involved in the local RC airplane club for quite a while if I recall correctly.
His website is well worth checking out, he has a very extensive technical knowledge.
