Ebook: Electromagnetic Simulation Techniques Based on the FDTD Method

Wiley & Sons, 2009, 206 pages, ISBN: 978-0-470-50203-7There exist several good books on the FDTD method and code development techniques. However, no literature focuses specifically on the simulation technique, although it has the same importance as the FDTD method. The simulation technique is a bridge between the FDTD method and applications. This book will help readers understand the FDTD method and design FDTD projects for practical problems using either commercial EM software packages or locally developed codes.
FDTD methods are well suited for analysil. of problems with complex geometrical feamres as well as those containing arbitrarily inhomogeneous materials. Also, the FDTD method does not require the derivation of a Green's function or the solution of a matrix equation-required in both MoM and FEM. Although the traditional FDTD technique does place a relatively heavy burden on computer resources when it is used to analyze a complex problem that occupies a large computational volume or includes very fine features. this problem can be solved using the parallel processing technique, for which the FDTD method is best fit. The parallel FDTD method has become a major EM tool for complex EM problems, due to the fast development of computer science and the low price of computer hardware. For example, one quad-node PC c luster represents only 10% of the cost of an EM software package today.
The book is divided into six chapters. ln the first two chapters we introduce the basic concepts of the three-dimensional Cartesian FDTD method. such as the update equations and boundary condilions, and follow this with a discussion of advanced FDTO methods. such as conformal techniques, dispersive media, circuit elements, and near-lo-far field transformation. In the third chapter we present the basic concepts of parallel processing techniques and systems, including parallel FDTD techniques and systems. ln the founh chapter we introduce simulation techniques based on FDTD method~. In the fifth chapter we describe the practical simu lation technique through some illustrative engineering applications. Finally, in the sixth chapter, we introduce some advanced simulation techniques.Introduction to FDTD Method.
