Electromagnetic waves

This introduction to electromagnetic waves emphasizes concepts, examples, and problem-solving techniques having wide applicability, and relies only on basic physics and mathematics -- rather than electrostatics, magnetostatics, and quasitatics. The focus is on generic problem-solving techniques -- both mathematical and physically-intuitive, and the presentation of basic electromagnetic theorems -- Poynting, energy, uniqueness, and reciprocity -- explained from a physical perspective. Progresses from simple wave propagation in unbounded free space to antenna and resonator design. Presents the fundamental concepts of plane waves, phasors, polarization, energy, power, and force early -- and repeatedly applies them throughout the text to problems with progressively more complex boundary conditions. For students and practicing engineers interested in electromagnetic wave phenomena. As educators, David H. Staelin, Ann W. Morgenthaler, and Jin Au Kong saw a need for a book presenting electromagnetic theory and applications in a clear, compact, and "user-friendly" manner relying only on basic physics and mathematics. The result is Electromagnetic Waves. This book provides thorough explanations and relevant, modern examples so that students and practicing engineers will find it a useful reference as well as a tool for self-teaching. It emphasizes basic concepts from both a physical and mathematical perspective. Successive chapters move from simple wave propagation in unbounded free space to the complexities of resonator and antenna design, revisiting basic concepts as each new topic is introduced. Electromagnetic Waves also makes connections between electromagnetics and simple equivalent circuit models wherever possible. The book exposes its readers to a considerable array of mathematical tools as well, ranging from orthogonal function expansions to perturbation techniques and duality, but physical intuition and approximate problem-solving techniques are also emphasized. For courses in advanced electromagnetics at the senior to graduate level. Assumes a first course background in electromagnetics. This intermediate text emphasizes concepts, examples, and problem-solving techniques having wide applicability, and relies only on basic physics and mathematics rather than electrostatics, magnetostatics, and quasistatics. The focus is on generic problem-solving techniques both mathematical and physically-intuitive, and the presentation of basic electromagnetic theorems Poynting, energy, uniqueness, and reciprocity explained from a physical perspective.
