((Expand)) I would like to see some of the physics behind this concept, instead of a general "this is the definition of shielding." - eykanal
It would also be a very good idea to quickly explain what "coupling" means. - Raeyin
RF shielding doesn't really cover anything that's specific to the field of RF. It should be merged here for now. — Omegatron 15:44, 23 March 2006 (UTC)
eykanal: see the page on a farady cage for more info.
Jenke: RF shielding can be quitte different to EM shilding, if the entries are similar then this needs to be addressed.
In the intro I changed the bit about "static magnetic fields" to "static or low-frequency magnetic fields". Also, on the "be bold with edits" principle, I removed "visible light" from the things shielded against. It is certainly true that a solid metal shield will block visible light, but there are a lot of very effective EM shields that don't block much visible light; and a lot of things that block visible light are not EM shields at all. (Er, well, they are, but only at very very short wavelengths!) I think the "visible light" claim is an example of something that is technically correct but practically misleading. Reply here, or revert, as you see fit! :) Jeh 06:08, 19 January 2007 (UTC)
This article was automatically assessed because at least one WikiProject had rated the article as start, and the rating on other projects was brought up to start class. BetacommandBot 09:49, 10 November 2007 (UTC)
Was looking for info on magnetic shielding and for some reason was redirected here. Decided to add a section on shielding and also created a references section. Not really happy with the section so I hope someone with more expertise will edit it. --Parabolis (talk) 01:33, 10 December 2007 (UTC)
I myself am a student, and I and others find Wikepedia a very useful research site. I generally however find it useful to have dictionary.com running aswell! This is because of the complex scientific language used throughout the site. I myself am in my top Science set at school and am gifted and talented, however I think this particular article definitely needs a bit of translation. Some people are probably put off by the very first sentance! For I think it doesn't really explain simply to begin. The detail is supposed to be added later on in the aticle. Please do not hate me for this comment, as said I and my fellow students really enjoy this site! —Preceding unsigned comment added by 81.178.73.198 (talk) 17:28, 17 January 2009 (UTC)
Are there any materials that shield magnetism but are not themselves attracted to magnets?Ratsbew (talk) 16:59, 12 April 2009 (UTC)
In the old tube type radios they had aluminum shields around the tubes for RF shielding; and they would probably develop internal currents such as to provide some amount of variable magnetic field shielding.WFPM (talk) 06:06, 17 February 2012 (UTC)

https://en.wikipedia.org/wiki/Tempest_(codename) TEMPEST is a National Security Agency specification and a NATO certification [1][2] referring to spying on information systems through leaking emanations, including unintentional radio or electrical signals, sounds, and vibrations.[3] TEMPEST covers both methods to spy upon others >>> and how to shield equipment against such spying <<<. The protection efforts are also known as emission security (EMSEC), which is a subset of communications security (COMSEC).[4] — Preceding unsigned comment added by 173.81.169.7 (talk) 20:31, 15 April 2018 (UTC)
In the mathematical model section the mathematical model is postulated as Ho*Vector(z)=H_r*Vector(r) - H_rho*Vector(theta)
If that would be the case then How would it work if theta was 90 degrees or pi/2 ? the component that has to be used is rho axis vector (as in rho=r*sin(theta)) (cylindrical coordinates) (rho=sqrt(x^2+y^2)).
z is not part of the spherical coordinates system but of cartesian and cylindrical. you cannot do Vector(r)-Vector(theta) and expect to have Vector(z). Ctmv (talk) 14:43, 2 September 2023 (UTC)
