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.
