Since Maxwell’s time, electromagnetic theory has made spectacular progress, particularly in the field of waves. Introduction to Classical Electrodynamics 2 presents the fundamental concepts of electromagnetic field theory.
This book first addresses static potentials with sources and provides a detailed presentation of the method of images and Green's functions. It also analyzes electromagnetic induction phenomena and Maxwell's equations. It examines electromagnetic waves in a vacuum and their properties, as well as the concept of electromagnetic energy. Finally, it covers polarized and magnetized media, along with electromagnetic fields and their propagation in material media.
This book is intended for physics and mathematics students, as well as engineering students interested in the challenges of electromagnetic theory. The discussion is supplemented with numerous applications derived from the theoretical concepts presented.
