Special Topics in Electromagnetics

Five special topics in Electromagnetics are covered in this book which can be taught as a graduate course in Electromagnetics. The prerequisite to understand this book is some experience in undergraduate courses on this subject.

The format of this book is somewhat unusual because the material is presented with detailed mathematical derivation, with an intention for self-taught students and researchers to read this book. The special topics covered in this book are becoming more popular in research areas of interaction of Electromagnetic field with material bodies, the practical applications of Electromagnetic wave in biomedical engineering, and the radar target identification.

陳坤木教授（KUN-MU CHEN）

Kun-Mu Chen graduated in 1955 with a B.S. degree in Electrical Engineering from National Taiwan University. He obtained a Ph.D. degree in Applied Physics from Harvard University in 1960. After graduating with his doctorate, he went to Michigan to start his teaching and research career. He began his professional career at the University of Michigan, Ann Arbor, and then in 1964, he joined the faculty of Michigan State University in East Lansing, Michigan. After a long and distinguished career at Michigan State University, he retired in 1999 as the Richard M. Hong Professor Emeritus of Electrical Engineering.

During his teaching and research career of 40 years, Dr. Chen produced many Ph.D. students who came from all over the world to work with him. He also published many papers, book chapters, and received many national research grants. His achievements have been recognized by receiving numerous awards that included the Outstanding Faculty Award and Excellent Research Award from Michigan State University, and the Science and Engineering Achievement Award from the Taiwanese American Foundation of Los Angeles, California in 1984.

He is a nationally and internationally-known scholar in Electromagnetics with specialities in electromagnetic theory, radar technology, plasma physics, and applications of electromagnetic radiation in biomedical areas. He is a Life Fellow of the Institute of Electrical and Electronic Engineers (IEEE) and a Fellow of the American Association of the Advancement of Science (AAAS).
