In this book the mathematical machinery underlying commonly encountered electromagnetic problems in antenna analysis and design, electromagnetic scattering and propagation, electromagnetic guiding, scattering control, radio imaging, and wireless communications is extracted and compiled in the form of theorems and principles. The matter is elucidated through several engineering examples. For instance, rather than discussing in detail the theory of waveguides with canonical geometries as a physical device having certain properties, as one would do in a traditional book on electrodynamics, an alternative approach where the waveguide field description is restricted to the description in terms of its eigenmodes is taken. Less common representation of fields that have escaped the attention of traditional treatments on the subject, but those that can lead to new theoretical results are prioritized.

Key Features:

  • Single book that contains relevant theorems, principles and integral representations of importance to engineering electromagnetics.

  • Includes new results not found in other books.

  • Demonstrates the application of the theory to facilitate a clear understanding of various theorems.

  • Emphasizes analysis as a complement as well as the building block to the more common approach of using computational/software tools in engineering problem solving.

  • End-matter and Appendices that contain valuable information on covariant formulation, special functions, and stochastic analysis.

Industry Reviews

I personally purchased the first edition of this book, and was extremely impressed by it. It was probably the most comprehensive collection of some of the most important principles in electromagnetics that I have ever seen. I believe it to be a great resource, and I would expect a second edition to elevate its usefulness even further. I have worked in this field for 30 years and feel that this work stands out as one of the best possible references for researchers and students alike - although I do believe it to be mostly a graduate level text.
