Overview

Electromagnetics for Practicing Engineers, Second Edition delivers an expanded, authoritative guide that fully integrates electromagnetic (EM) theory with the most critical real-world design and safety applications. The book transforms abstract EM concepts directly into effective, implementable strategies for solving practical design challenges in complex aerospace, defense, and commercial systems. Practitioners gain the expertise necessary to diagnose and resolve field complications, ensuring system integrity and reliability.   The text meticulously covers fundamental principles, including a thorough review of vector analysis and Coulomb forces, and details the critical roles of capacitance, dielectric materials, and inductance in system design. Detailed methodologies demonstrate the application of Gauss’ Law to field calculations, the use of Laplace’s Equation to resolve potential complications, and the analysis of displacement current and induced EMF in magnetic circuits. New chapters introduce guidance on free-space topics, specifically addressing electromagnetic wave propagation, boundary conditions, and Maxwell’s Equations for high frequency analysis.   This updated reference provides immediate value for practicing electrical engineers, aerospace and defense technologists, RF designers, and advanced students seeking expert applied guidance. The practical case studies and solutions (derived directly from the author’s work) show how to mitigate specific field challenges, such as reducing static charge in liquid fuel systems, achieving accurate fuel sensing in aircraft tanks, or predicting attenuation effects at higher frequencies. This book will equip engineers with the theoretical grounding and technical methods required to handle complex electromagnetics comfortably.

Author Information

earned his B.S. in electrical engineering from the University of Maryland in 1953 and worked at RCA Laboratories on early color TV broadcast systems and the first transistor radios. After completing his Ph.D. at the University of Wisconsin in 1962, he joined the faculty at Iowa State University, where he taught for nearly three decades, originated courses in information theory, error-correcting codes, and analog filter design, and twice received Professor of the Year honors. He was the first at ISU to teach SPICE for circuit analysis, contributed to advances in digital compression and coding methods, and in retirement continued to support students through textbooks, solution manuals, and simulation tools.
