Electromagnetic wave equations: dielectric without dispersion
... Since w is assumed small, the second term is a small correction. Spatial nonuniformtiy of the field (skin effect) becomes important in metals sooner. Griffiths keeps the second term from the beginning, but this only results in more complicated formulae for the complex wave-vector without a significa ...

Electromagnetic energy and momentum
... We will assume that any medium is linear, so that D = E and H = µ1 B. First, compute the work done by the electromagnetic fields on a system of particles. For a single particle, we have the Lorentz force law, F = q (E + v × B) and this provides the entire basis for extending mechanical energy and m ...

... in momentum of the particle is ∆m~v = −q A. There is at least one thing odd about this. The magnetic field can change very quickly leading to ~ However, the charged particle can have a large mass; be me for instance. a quick change in A. Obviously my momentum doesn’t change very quickly. The momentu ...
