Hi guys, I have been given a text entitled 'Classical Electrodynamics' Authored by John Jackson, it is an excellent text for describing and deriving all EM related matters. No application to our SI related issues but is excellent for finding out say how a field solver would work etc. It has a section which describes where the skin depth symbol 'delta' comes from however the description in beyond my understanding and loses me early on. Does anyone have a good link or information source for me that would be able to derive the skin depth equation in terms of physics? Many thanks in advance Mark Mr Mark R.
