The problem of radia- tion will be addressed in Chapter 13. In this chapter, our major goal is to solve Maxwell's equations and derive EM wave motion in the following media: 1. Free space (<T = 0, s = eo, JX = /xo). 2. Lossless dielectrics (a = 0, e = e,so, JX = jxrjxo, or a <sC aie). 3. Lossy dielectrics {a # 0, e = E,EO, fx = fxrixo).

In a dielectric (equivalently, an insulator), the vacuum quantities µ0 and ?0 in Maxwell's equations are replaced by new values, µ and ?. (We'll give some justification of this below, but see Sections 10.11 and 11.10 in Purcell's book for the full treatment.) Our derivation of the wave equation for electromagnetic waves in a
microscopic current. In an oscillating field, the effective permittivity becomes frequency dependent, and electromagnetic waves in dielectrics are strongly dispersive in contrast to waves in free space. In this Chapter, we will study electromagnetic wave propagation in conductors, dielectrics and plasmas. 10.2 Skin Effects in

For the dielectric materials used to guide high frequency electromagnetic waves. (which we will mainly consider here) the conductivity is typically zero, while the permeability is that of free space. The former implies that the current density J is zero; there are also no free charges, so that ? is zero. However, this is not quite the
