I have been reading the groups archives on shield antennas and Faraday shields and the different auguments regarding how shielding or the Faraday shield works. Frankly it is a total mess and should be removed so that hams are not mislead. Shielding is very simple. A particle with a electromagnetic field strikes the outside of the shield. The magnetic field of same passes thru the shield some might say it is coupled to the inside of the shield. The magnetic vector component is out of phase with the electrical field so it will be just a static particle at rest on the inside but no inline with the electrical field vector which is now a staic particle at rest on the outside We now have a arbitrary boundary as discused by Gauss For equilibrium all vectors impinging on the boundary must be aligned such that they cancel. To accomplish this the inner vector or charge MUST move sideways snip crap, but left plenty WOW!!! Look everybody he's totally making up physics again!
