Electromagnetic waves in dielectrics
Consideration of the propagation of electromagnetic waves in matter can be conveniently divided into two cases: (1) dielectrics, i.e. media in which there are no conduction electrons, and (2) conductors. Many gases, liquids and solids are good dielectrics and we begin with the effects of an oscillating electric field on such dielectrics. We then solve Maxwell’s equations for linear, isotropic dielectrics and finally discuss the absorption and dispersion of electromagnetic waves in polar and non-polar dielectrics.
