This is an advanced undergraduate course on electromagnetic theory. The course aims at introducing concepts of classical electrodynamics, especially electromagnetic waves and radiation and their applications, in various situations at the undergraduate level. The concepts of energy, momentum and angular momentum of electromagnetic fields will be introduced as a basis for understanding the properties of electromagnetic waves. Optical phenomena such as reflection and refraction, absorption and dispersion of light, will be explained. The retarded potentials will be derived as a solution to Maxwell equations and applied to illustrate the generation of radiation by moving point charges, as well as electric and magnetic dipoles. The relation between electromagnetism and special relativity is discussed.
