Computational Electrodynamics: The Finite-Difference Time-Domain Method, Third Edition

The first and second editions of this book were published in 1995 and 2000, respectively. We are gratified with their high level of use by both the university and industrial-research communities. The second edition is often the text in senior year and graduate electrical engineering courses in computational electrodynamics, and both editions are frequently cited in refereed journal papers as primary background references for FDTD methods and applications. This new third edition is extensively revised and expanded. We have had two primary goals in this regard. First, we have worked to update the book’s discussions of FDTD theory and applications to keep pace with the continuing, rapid changes in these areas since 2000. This allows the professional engineer or scientist to have a convenient single-source reference concerning the latest FDTD techniques and research problems. Second, we have worked to further enhance the educational content of the book from both a fundamental theoretical perspective, and from the standpoint of the course instructor’s ease of use.

This extensively revised and expanded third edition of the Artech House bestseller, Computational Electrodynamics: The Finite-Difference Time-Domain Method, offers engineers the most up-to-date and definitive resource on this critical method for solving Maxwell's equations. The method helps practitioners design antennas, wireless communications devices, high-speed digital and microwave circuits, and integrated optical devices with unsurpassed efficiency. There has been considerable advancement in FDTD computational technology over the past few years, and the third edition brings professionals the very latest details with entirely new chapters on important techniques, major updates on key topics, and new discussions on emerging areas such as nanophotonics. What's more, to supplement the third edition, the authors have created a Web site with solutions to problems, downloadable graphics and videos, and updates, making this new edition the ideal textbook on the subject as well.

"This single resource provides complete guidance on FDTD techniques and applications, from basic concepts to the current state of the art. It enables professionals to more efficiently and effectively design and analyze key electronics and photonics technologies, including wireless communications devices, high-speed digital and microwave circuits, and integrated optics. It is also ideal for senior-year and graduate-level university courses in computational electrodynamics. In addition, to supplement the third edition, the authors and publisher have created a Web site where instructors can find solutions to the problems, sample FDTD PML codes, text updates/errata, and downloadable color graphics and videos."--Jacket
