Book Description:
Elements of Electromagnetics, Fourth Edition, uses a vectors-first approach to explain electrostatics, magnetostatics, fields, waves, and applications like transmission lines, waveguides, and antennas. It also provides a balanced presentation of time-varying and static fields, preparing students for employment in today's industrial and manufacturing sectors. Streamlined to facilitate student understanding, this edition features worked examples in every chapter that explain how to use the theory presented in the text to solve different kinds of problems. Numerical methods, including MATLAB and vector analysis, are also included to help students analyze situations that they are likely to encounter in industry practice. Elements of Electromagnetics, Fourth Edition, is designed for introductory undergraduate courses in electromagnetics. An Instructor's Solutions Manual (co-authored by Sudarshan Rao Nelatury of Penn State Erie, The Behrend College) and PowerPoint slides of all figures in the text are available to adopters.
ABOUT THE AUTHOR:
Matthew N. O. Sadiku is Professor in the Department of Electrical Engineering at Prairie View A&M University. He is the author of more than one hundred professional papers and fifteen books, including Fundamentals of Electric Circuits (2002), Metropolitan Area Networks (1994), and Numerical Techniques in Electromagnetics (1992).
Table of Contents:
The fundamental objectives of the book remains the same as in the first edition to present
Electromagnetic (EM) concepts in a clearer and more interesting manner than earlier texts.
This objective is achieved in the following ways:
1. To avoid complicating matters by covering EM and mathematical concepts simultaneously,
vector analysis is covered at the beginning of the text and applied gradually.
This approach avoids breaking in repeatedly with more background on vector analysis,
thereby creating discontinuity in the flow of thought. It also separates mathematical theorems
from physical concepts and makes it easier for the student to grasp the generality of
those theorems.
2. Each chapter starts with a brief introduction that serves as a guide to the whole
chapter and also links the chapter to the rest of the book. The introduction helps students
see the need for the chapter and how the chapter relates to the previous chapter. Key points
are emphasized to draw the reader's attention to them. A brief summary of the major concepts
is provided toward the end of the chapter.
3. To ensure that students clearly understand important points, key terms are defined
and highlighted. Essential formulas are boxed to help students identify them.
4. Each chapter includes a reasonable amount of examples with solutions. Since the
examples are part of the text, they are clearly explained without asking the reader to fill in
missing steps. Thoroughly worked-out examples give students confidence to solve problems
themselves and to learn to apply concepts, which is an integral part of engineering education.
Each illustrative example is followed by a problem in the form of a Practice Exercise,
with the answer provided.
5. At the end of each chapter are ten review questions in the form of multiple-choice
objective items. It has been found that open-ended questions, although intended to be
thought provoking, are ignored by most students. Objective review questions with answers
immediately following them provide encouragement for students to do the problems and
gain immediate feedback.
A large number of problems are provided are presented in the same order as the material
in the main text. Problems of intermediate difficulty are identified by a single asterisk;
the most difficult problems are marked with a double asterisk. Enough problems are pro
Vided to allow the instructor to choose some as examples and assign some as homework
problems. Answers to odd-numbered problems are provided in Appendix C.
6. Since most practical applications involve time-varying fields, six chapters are
devoted to such fields. However, static fields are given proper emphasis because they are
special cases of dynamic fields. Ignorance of electrostatics is no longer acceptable because
there are large industries, such as copier and computer peripheral manufacturing, that rely
on a clear understanding of electrostatics.
7. The last chapter covers numerical methods with practical applications and computer
programs. This chapter is of paramount importance because most practical problems
are solvable only by using numerical techniques.
8. Over 130 illustrative examples and 400 figures are given in the text. Some additional
learning aids, such as basic mathematical formulas and identities, are included in the
Appendix. Another guide is a special note to students, which follows this preface.
In this edition, a new chapter on modern topics, such as microwaves, electromagnetic
interference and compatibility, and fiber optics, has been added. Also, the Fortran codes in
previous editions have been converted to Matlab codes because it was felt that students are
more familiar with Matlab than with Fortran.
Although this book is intended to be self-explanatory and useful for self-instruction
the personal contact that is always needed in teaching is not forgotten. The actual choice o1
course topics, as well as emphasis, depends on the preference of the individual instructor
For example, the instructor who feels that too much space is devoted to vector analysis o:
static fields may skip some of the materials; however, the students may use them as refer
ence. Also, having covered Chapters 1 to 3, it is possible to explore Chapters 9 to 15. In
structors who disagree with the vector-calculus-first approach may proceed with Chapter;
1 and 2, then skip to Chapter 4 and refer to Chapter 3 as needed. Enough material i
covered for two-semester courses. If the text is to be covered in one semester, some sec
tions may be skipped, explained briefly, or assigned as homework.
