Does a Faraday Cage trap EMF inside and increase exposure?

[QUOTE="berkeman, post: 6812763, member: 8921"] Sorry, which part of your previous reply? Are you familiar with "standing waves" that form when two or more traveling waves (like sound or EM waves) combine? You can get "constructive" and "destructive" interference when two waves of similar/same wavelength combine. [URL]https://en.wikipedia.org/wiki/Standing_wave[/URL] As the first animation on that Wikipedia page shows, when you have two waves that are moving past each other (like bouncing around inside your Faraday Cage enclosure), the combination of the two waves can add up to a higher amplitude at some locations and cancel each other out at other locations. Those are called the "nodes" and "antinodes" of the standing wave, respectively. So the little longer answer to your question about exposure to higher EM inside a Faraday Cage as opposed to outside depends on the wavelength of the EM and the size of the Faraday Cage, and where you happen to be standing in the enclosure (near a node or antinode). But even if you manage to stand right at a node inside the enclosure, you are only exposed to a bit more peak energy than the average that you would experience out in an open field at the same distance from a transmitting antenna. I hope that makes some sense. :smile: [/QUOTE]
