Title: Bad News
Post by georgej on Feb 14^th, 2007, 1:48am

This from MIT:

"The effectiveness of the tin-foil hat as an electromagnetic shield for stopping radio waves is greatly reduced by the fact that it is not a complete enclosure. Placing an AM radio under a metal bucket without a conductive layer underneath demonstrates the relative ineffectiveness of such a setup. Indeed, because the effect of an ungrounded Faraday cage is to partially reflect the incident radiation, a radio wave that is incident on the inner surface of the hat (i.e., coming from underneath the hat-wearer) would be reflected and partially 'focused' towards the user's
brain. While tin-foil hats may have originated in some understanding of the Faraday cage effect, the use of such a hat to attenuate radio waves belongs properly to the realm of pseudoscience.

A study by graduate students at MIT determined that a tin-foil hat could either amplify or attenuate incoming radiation depending on frequency; the effect was observed to be roughly independent of the relative placement of the wearer and radiation source. Note that at GHz wavelengths, the skin depth is less than the thickness of even the thinnest foil."
