The notes were intended to supplement the textbook I used for the course, Computational Electrodynamics: The Finite-Di.erence Time-Domain Method by Ta.ove and Hagness (3rd ed., Artech House, 2005). The goal of the course was to provide students not only with a thorough understanding of the FDTD method, but also to ensure they were able to implement functional FDTD code and to tackle meaningful, challenging, and interesting problems. (For example, one of the homework assignments in the class was to duplicate the patch antenna modeling in David Sheen’s groundbreaking 1991 MIT Ph.D. dissertation.) Each time I taught the course I added to the notes to the point that students believed the assigned textbook should be considered optional, i.e., the material I provided stood on its own as a complete text in and of itself. I have shared the English version of the course material widely and have been .attered by the response. From the feedback I have received, the material has served individuals interested in learning the FDTD method and writing functional code extremely well. Although this material was used in a graduate-level course, undergraduate students often took the course. They only needed to be su.ciently motivated, to have had an introductory course in electromagnetics and, hopefully, to have had some programming experience. I truly feel that by understanding the FDTD method one can better understand Maxwell’s equations and electromagnetics in the continuous world. Thus, I can easily envision this material servingas the textbook for an upper-division undergraduate course. The FDTD method is computationally expensive. Many interesting simulations can be quickly and easily realized in languages such at MATLAB or Java, but to get the most from the technique it is necessary to code in a computationally e.cient language such as FORTRAN or C. In this book, C is the language of choice. Although C may be considered arcane or archaic by some, as used here it is quite accessible—readers need not have much, or perhaps even any, familiarity with C. The FDTD method, at its core, is an extremely simple technique and if you are able to implement a FOR-loop, you have almost all the coding skills you need to do meaningful simulations (a slight exaggeration, perhaps, but as you will see, only a slight one). Finally, the Chinese edition of this material would not exist without the work of Prof. Wenhua Yu and his students. Thus, I would like to express my deep appreciation to Prof. Yu for reaching out to me and to all those who made the translation of this material possible.
