First published in 1941, Julius Stratton's classic Electromagnetic Theory has been a mainstay for generations of students, researchers, and scientists. This classic reissue of the original features a Foreword to the Classic Reissue by Dr. Donald G. Dudley that details the book's contribution to the field and an introductory biography by Dr. Paul E. Gray, former MIT President and colleague of Dr. Stratton. This respected and frequently cited text remains as useful and relevant as ever, with areas of particular interest to today's students and researchers that include: * The discussion of Hansen vector wave functions * The outstanding treatment of phase and group velocity * The Stratton-Chu formulation for integration of the vector Helmholtz equations * The development of the source-free solutions for a circular cylinder in a lossy medium * The treatment of spherical vector wave expansions The IEEE Press Series on Electromagnetic Wave Theory offers outstanding coverage of the field. It consists of new titles of contemporary interest as well as reissues and revisions of recognized classics by established authors and researchers. The series emphasizes works of long-term archival significance in electromagnetic waves and applications. Designed especially for graduate students, researchers, and practicing engineers, the series provides affordable volumes that explore and explain electromagnetics waves beyond the undergraduate level.
