Electromagnetic Fields and Waves
Second Edition
The latest edition of Electromagnetic Fields and Waves retains an authoritative, balanced approach, in-depth coverage, extensive analysis, and use of computational techniques to provide a complete understanding of electromagnetics—important to all electrical engineering students.
An essential feature of this innovative text is the early introduction of Maxwell’s equations, together with the quantifying experimental observations made by the pioneers who discovered electromagnetics. This approach directly links the mathematical relations in Maxwell’s equations to real experiments and facilitates a fundamental understanding of wave propagation and use in modern practical applications, especially in today’s wireless world. New and expanded topics include the conceptual relationship between Coulomb’s law and Gauss’s law for calculating electric fields, the relationship between Biot-Savart’s and Ampere’s laws and their use in calculating magnetic fields from current sources, the development of Faraday’s law from experimental observations, and a comprehensive discussion and analysis of the displacement current term that unified the laws of electromagnetism. The text also includes sections on computational techniques in electromagnetics and applications in electrostatics, in transmission lines, and in wire antenna designs. The antennas chapter has been substantially broadened in scope; it now can be used as a stand-alone text in an introductory antennas course.
Advantageous pedagogical features appear in every chapter: examples that illustrate key topics and ask the reader to render a solution to a question or problem posed; an abundant number of detailed figures and diagrams, enabling a visual interpretation of the developed mathematical equations; and multiple review questions and problems designed to strengthen and accelerate the learning process. Helpful material is included in six appendices, including answers to selected problems. Unlike other introductory texts, Electromagnetic Fields and Waves does not bog readers down with equations and mathematical relations. Instead, it focuses on the fundamental understanding and exciting applications of electromagnetics.
