Electromagnetic Waves in Anisotropic-Dispersive Media


In Chapters 1 and 3, we examined the basic theory of magnetism and developed a model for the magnetic susceptibility tensor of a saturated ferro- or ferrimagnetic insulator. In this chapter, we will examine the properties of electromagnetic waves traveling in media characterized by frequency-dependent electric and magnetic susceptibilities. We then combine this formalism with the Polder susceptibility tensor to obtain the properties of electromagnetic waves in saturated magnetic insulators.
