#### Description of The Finite Difference Time Domain Methods for Electromagnetics (PDF)

The Finite Difference Time Domain Methods for Electromagnetics by Karl S. Kunz & Raymond J. Luebbers is a great Electromagnetics book available for (eBook) PDF download. The finite-difference time-domain (FDTD) approach is rapidly becoming one of the most widely used computational methods in electromagnetics. There are several reasons for this, including the increased availability of low cost but powerful computers, and increasing interest in electromagnetic interactions with complicated geometries, which include penetrable dielectric and/or magnetic materials. Just as important perhaps is the extreme simplicity of the method. The fundamentals of FDTD can be grasped easily by undergraduate students, more easily than traditional frequency-domain approaches to electromagnetics. Yet FDTD is capable of computing electromagnetic interactions for problem geometries that are extremely difficult to analyze by other methods. It is this combination of simplicity and power that makes FDTD such a popular method.

This also allows this The Finite Difference Time Domain Methods for Electromagnetics book to serve a wide range of potential readers. It can be used to introduce undergraduate students to time-domain electromagnetics, in which case only the first two parts of the book need be covered. It can be used in a graduate-level course, in which case the mathematical basis of FDTD would be emphasized with topics selected from the sections on special capabilities and advanced applications at the discretion of the instructor. Finally, someone who wants to use FDTD to solve a particular problem in electromagnetics can use the book to learn FDTD basics and special capabilities necessary for their application. In addition, it can be seen, through the examples in this book, how FDTD has been applied to a variety of problems.
