Expert guidance helps you solve electromagnetic problems across a diverse range of industries

Learn to solve both simple and complex electromagnetic problems with this text's unique integration of theoretical and mathematical concepts. With the author's guidance, readers discover a broad range of classic and cutting-edge applications across a wide array of fields, including biomedicine, wireless communication, process control, and instrumentation. Case studies, detailed derivations, and 170 fully solved examples deepen readers' understanding of theory, and help them to apply numerical methods to real-world problems.

Following an introduction to complex numbers and functions and a chapter on vector analysis, the book covers:
_ Basic laws of electromagnetics, including Maxwell's equations and the Lorentz force equation
_ Uniform plane waves
_ Transmission line circuits
_ Modified Maxwell's equations and potential functions
_ Source in infinite space
_ Electrostatic and magnetostatic fields, including analysis of electrostatic problems via Poisson's and Laplace's equations
_ Waveguides and cavity resonators
_ Numerical techniques, including finite difference methods and the method of moments

In addition to the worked examples, 225 practice problems are provided to help readers apply their skills. Appendices include a wealth of helpful advanced mathematics data and information. For readers wishing to study particular topics in greater depth, extensive references are provided.

With its emphasis on applications, this text is ideal for practicing engineers and scientists. Based on more than twenty-five years of the author's hands-on teaching experience, this text is also perfect for undergraduate and beginning graduate students in electrical engineering and physics. Chapters are self-contained and organized to allow instructors flexibility in presenting topics and integrating the text into their course.
