Introduction to Electromagnetic Fields, Radiation and Antenna Theory: Fundamental Concepts and Engineering Applications

Introduction to Electromagnetic Fields, Radiation and Antenna Theory is a text book at the introductory graduate or senior-undergraduate level in electrical engineering. It introduces electromagnetic field theory starting from electrical circuits concepts, quickly establishing Maxwell's equations from basic electro- and magneto-static principles. Fundamental concepts are explained using integral expressions, which are intuitive to understand, without heavy dependence on differential operators that are mathematically more involved. Elementary antenna radiation is derived from superposition of simple plane waves. The book introduces, for the first time, a full derivation of Maxwell's equations from simple space-time relations of special relativity and basic principle of charge invariance, making the electromagnetic concepts less mysterious to understand. Some of the other special features of the book are to introduce radiation from an accelerating charge, surface-wave radiation at a dielectric interface, antenna performance in a scattering environment, method of moments analysis, and microstrip antenna. The same text book can be used for a starting course on electromagnetic theory and/or antennas, which is also another special feature of the book.
