Electromagnetic Computation Methods for Lightning Surge Protection Studies
by Yoshihiro Baba, Vladimir A. Rakov
Preface
This book aims at providing an introduction to electromagnetic computation methods with a focus on the finite-difference time domain (FDTD) method for lightning surge protection studies. The FDTD method is based on a simple procedure, and therefore its programming is relatively easy. Also, it is capable of treating complex geometries and inhomogeneities, as well as incorporating nonlinear effects and components.
The first peer-reviewed paper in which the FDTD method was used in surge simulation was published in 2001. More than 60 journal papers and a large number of conference papers, in which the FDTD method is used in lightning electromagnetic field and surge simulations, have been published during the last 15 years. Interest in using the FDTD method continues to grow because of the availability of both commercial and noncommercial software and increased computer capabilities.
The prerequisites for courses based on this book are fundamental electromagnetics, engineering mathematics, and programming. It is suitable for senior undergraduate and graduate students specializing in electrical engineering, as well as for electrical engineers and researchers who are interested in lightning surge protection studies.
This book is composed of four chapters. In Chapter 1, we give an overview of lightning electromagnetic-field and surge computations, and introduce the existing electromagnetic computation methods. In Chapter 2, we explain how lightning discharges are generated. ...
