Fundamentals of Electromagnetism. Vacuum Electrodynamics, Media, and Relativity. This textbook is a revised and enlarged version of notes written for a one-semester course on electromagnetism. It covers the theory of electromagnetic phenomena in vacuum and in material media. In addition to the classical themes of electrodynamics, the book deals with some related subjects of particular current interest, such as superconductivity and numerical methods. Much emphasis is put on special relativity, in the covariant formulation of electromagnetism, and in the symmetry properties of the theory. The book includes a CD-ROM with didactic software, to solve boundary value problems in electrostatics and magnetostatics. The book is conceived in such a way as to guide the reader from the fundamentals of the theory to its most recent modern applications. 294 pages.
