Computational Electromagnetics with MATLAB, Fourth Edition by Matthew N.O. Sadiku pdf.

Since the third edition of this book was published, there has been a noticeable increase of interest in computational electromagnetics (CEM), also known as numerical electromagnetics. This is evident by the amount of dissertations, theses, books, and articles on CEM appearing in journals and conferences each year. Along with this development is the rapid growth in commercial or free codes for designing complex EM problems. In spite of these cheap and powerful computational tools, there is a need to learn the fundamental analytical and numerical concepts behind the codes. It is beneficial to understand the inherent limitations of the commercial software. Experience shows that students learn more by developing their codes than just pushing buttons in a commercial software package. Also, a closer look at the newly published books reveals that they are not suitable for classroom use due to lack of examples and practice problems at the end of each chapter. There is still a need for a good introductory textbook for the CEM community. This book meets the need. The book has the following features:

• It is comprehensive. Some CEM books cover just one numerical technique, while some cover only finite difference method (particularly FDTD), finite element method, and method of moments. In addition to these, this present book covers variational methods, transmission-line-modeling (TLM), method of lines, and Monte Carlo method.
• It presents several examples with MATLAB codes where applicable. I believe that CEM is best learned through direct programming. Commercially packaged programs can be useful, but they should not take priority over direct programming.
• It provides several end-of-chapter problems with answers to odd-numbered problems in Appendix E.
• Each chapter presents a clear, concise introduction to a numerical method in EM and provides up-to-date references to information on the method. The last section of the chapter is devoted to application(s) of the method.

When the first edition of this book was written, the term “Computational Electromagnetics” was not common. Now, it is the most common term used in describing the emerging field. Since it is expedient to use the latest term or development, the former name of the book, Numerical Techniques in Electromagnetics, has been changed to Computational Electromagnetics with MATLAB®. This is part of the process of making another edition—catching up with the trends in this exciting field.

Although the book can be covered in one semester, enough material is provided for twosemester coverage. For two-semesters, it is suggested that Chapters 1 through 5 be covered in one semester, while Chapters 6 through 9 is covered in the second semester. In addition to serving as an introductory text for students, the book will also serve as a concise, up-todate reference for researchers and professionals in CEM.

The book provides a comprehensive bibliography that serves as the best resources for learning more about CEM. Appendix A is on vector analysis, while Appendix B provides programming in MATLAB. Appendix C covers briefly direct and iterative procedure for solving simultaneous equations. Appendix D provides a list of software packages that are either free or commercially available. Appendix E provides answers to odd-numbered problems.

Since the publication of the last edition, there has been increased awareness and utilization of computational tools. This edition adds noticeable changes in Section 5.2 on how moment methods can be used to solve differential equation, in section 310 on advanced applications of FDTD, in Section 6.12 on using a commercial solver to analyze microstrip lines, and in Section 8.7 on applying Monte Carlo Markov chain to Poisson equation.
