Electromagnetic Radiation: Variational Methods, Waveguides and Accelerators

This book is addressed to students in physics, electrical engineering, and applied mathematics who seek a thorough introduction to electromagnetism with emphasis on radiation theory and its applications. It was developed out of lectures and manuscripts by Julian Schwinger prepared during WWII at MIT's Radiation Laboratory, updated with previously unpublished material developed by Schwinger at UCLA in the 1970s and 1980s, and by Milton at the University of Oklahoma since 1994. The book includes a great number of straightforward and challenging exercises and problems. A hardcover edition containing additionally the reprints of more than 15 papers by Schwinger on these topics is available separately.
