This lecture covers the exact solution of electromagnetic radiation, including topics such as Maxwell equations, constitutive relations, monochromatic plane waves, free space radiation, vector potential, scalar potential, electromagnetic duality, transmission line theory, Fresnel coefficients, dispersive media, and Lorentz reciprocity. The instructor discusses the fundamental theorems, infinitesimal dipole, uniqueness of the field, and Huygens equivalence principle, providing insights into the behavior of electromagnetic fields in different media.
