Electrodynamic Theory of Superconductors is the first book of its kind. It gives a unified and comprehensive theoretical treatment of electromagnetic, thermal and mechanical phenomena in superconductors. Basic concepts and principles in continuum electrodynamics are introduced, with particular emphasis on methodology. Electrodynamic models are developed to study magnetoelastic and thermoelastic superconductors. The author also introduces phenomenological London theory, Cinzburg-Landau theory, electrodynamic models for superconducting thin films, AC losses and Josephson junctions, and BCS microscopic theory of superconductivity. This book can be used as a post graduate level text and as a reference book for researchers and engineers working in the field of applied superconductivity and related areas.
