Lecture
This lecture covers the behavior of electromagnetic waves in dielectric media, focusing on the creation of polarization density in response to an electric field. Topics include linear, nondispersive, homogeneous, and isotropic media, as well as anisotropic media and refractive indices. The lecture also delves into inhomogeneous media, tensorial susceptibility, permittivity, and the characteristics of anisotropic crystals. Additionally, it explores nonlinear media, the breakdown of the superposition principle, and the nonlinear relation between polarization and electric field strength.
