Classical Electromagnetism in a Nutshell, by Anupam Garg. Princeton U. Press
Carryover form the end of PHYS 203A, from Fields from accelerated charges. Radiation from charges in circular motion; spectrum and agular distribution of intensity of radiation, periodic sources, Airy functions.
Classical electron theory. Inconsistencies of classical electrodynamics. Radiation reaction. Classical line width.
Modern treatment of radiation reaction, preserving covariance.
Review of electrostatics as an excuse to introduce multi-pole expansion and Spherical Harmonics. Boundary value problems: solve Laplace equation by separation of variables in Cartesian, Cylindrical and Spherical Coordinates. Multipole expansion: field ude to localized charge distribution. Localized charge in external fields.
General expressions for radiation fields and differentail power distributions (spectral and angular). Types of sources. Long wavelength (non-relativistic) approximation and multipole expansion. Antennae.
Averaging out microscopic fields and current/charge densities. Constitutive relations, electric and magnetic susceptibility, permittivity, permeability. Energetics.
