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. KEY TOPICS: 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. MARKET: For students and practicing engineers interested in electromagnetic wave phenomena.
