Thanks for your responses. The link I posted was an example of all I could find on the web, not my personal preferences, but you get the idea. I tried calling my cell phone in my microwave and had no signal; interesting, perhaps the 'tyre kickers' way to shop for a safer microwave! This is part of a larger experiment and I'm only loosely drafting the framework. Current considerations are does it work or would it be possible, and how would you measure it? It's really to see how much of the surrounding environment is saturated by modern radio waves (since the first broadcast on December 24, 1906 from Brant Rock), and look at how much effort is required to shield it. Whether it's pointless or redundant isn't the point in this instance, it's a controlled experiment to see if it's possible and measure the difference between them. Disappointingly, a frequency is a measurable dimension and depending on wave frequency and mesh size, some will fit through larger meshes and be stopped by smaller ones accordingly. Besides a metal box, the alternative is to stop all radio waves above and below the visible range of the Electromagnetic Spectrum. Or click here for a more enjoyable version. With emphasis on the modern waves, it would be interesting to better understand the frequencies in use above, from 1900 to 2010.

Greetings all, my first post here is a topic of great personal interest originating from a movie. It's something I have struggled to find online and it's either very simple or very complex. Either way I haven't found links about it which tells me I'm looking for the wrong thing, no-one cares or it simply isn't possible. We've probably all seen Gene Hackman and Will Smith in Enemy of the State. 'Brill' used a copper mesh cage to shield himself from external radiation. This made me wonder if this would actually work? Stop cell phones having reception. Prevent harmful radio waves passing through (eg. GSM, Radar, Television, satellite, appliance etc..) We weren't always exposed to this level of radiation, could it be shielded, could it be measured? - (beside a cell phone not having a signal). If it would work how would it work, a simple earthed mesh? Would it have to be copper? Found this site.
