The article appears to have some sort of bad science. > This effect was first discovered back in 1836 by physicist Michael Faraday, and it works in a similar way to noise-cancelling headphones, which block out noise by emitting the opposite wavelengths of sound. > So, when electromagnetic radiation - such as a phone signal - hits the outside of a Faraday cage, it causes electrons in the metal to move and create an electromagnetic field that exactly opposes and cancels out that wavelength of radiation. They make it sound like the mesh is actively generating an opposing signal to cancel out the cell phone signals, which is pretty far from the truth. I think the article writer looked up info on how faraday cages use charge imbalances and then figured they were just like active noise cancellation headphones.. somehow.
