Contents 3 Vector Calculus 53 3. Contents 8. PREFACEThe fundamental objectives of the book remains the same as in the first edition—to presentelectromagnetic EM concepts in a clearer and more interesting manner than earlier texts. This objective is achieved in the following ways: To avoid complicating matters by covering EM and mathematical concepts simul-taneously, 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 theo-rems from physical concepts and makes it easier for the student to grasp the generality ofthose theorems. Each chapter starts with a brief introduction that serves as a guide to the wholechapter and also links the chapter to the rest of the book. The introduction helps studentssee the need for the chapter and how the chapter relates to the previous chapter.

Key pointsare emphasized to draw the readers attention to them. A brief summary of the major con-cepts is provided toward the end of the chapter. To ensure that students clearly understand important points, key terms are definedand highlighted. Essential formulas are boxed to help students identify them.

Each chapter includes a reasonable amount of examples with solutions. Since theexamples are part of the text, they are clearly explained without asking the reader to fill inmissing steps. Thoroughly worked-out examples give students confidence to solve prob-lems themselves and to learn to apply concepts, which is an integral part of engineering ed-ucation. Each illustrative example is followed by a problem in the form of a Practice Exer-cise, with the answer provided.

At the end of each chapter are ten review questions in the form of multiple-choiceobjective items. It has been found that open-ended questions, although intended to bethought provoking, are ignored by most students. Objective review questions with answersimmediately following them provide encouragement for students to do the problems andgain immediate feedback. A large number of problems are provided are presented in the same order as the mate-rial 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- XIII 9.

Answers to odd-numbered problems are provided in Appendix C. 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.

The last chapter covers numerical methods with practical applications and com- puter programs. This chapter is of paramount importance because most practical problems are solvable only by using numerical techniques. Over illustrative examples and figures are given in the text.

Some addi- tional 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: Also, having covered Chapters 1 to 3, it is possible to explore Chapters 9 to 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. Sections marked wit! A suggested schedule for a four-hour semester coverage is on page xv. Acknowledgments I would like to thank Peter Gordon and the editorial and production staff of Oxford Un versity Press for a job well done.

This edition has benefited from the insightful commeni of the following reviewers: Leo C. Saroj Biswas for helping with Matlab. I owe special thanks to Dr. Keya Sadeghipour, de; of the College of Engineering, and Dr. Digestive System Diseases: Stem Cell Mechanisms and Therapies.

EM principles find applications in various allied disciplines such as microwaves, an- tennas, electric machines, satellite communications, bioelectromagnetics, plasmas, nuclear research, fiber optics, electromagnetic interference and compatibility, electromechanical energy conversion, radar meteorology," and remote sensing.

EM fields are used in induction heaters for melting, forging, annealing, surface hardening, and soldering operations. Dielectric heating equipment uses shortwaves to join or seal thin sheets of plastic materials. EM energy offers many new and exciting possibilities in agriculture. It is used, for example, to change vegetable taste by reducing acidity.

The design of these devices requires thorough knowledge of the laws and principles of EM. For numerous applications of electrostatics, see J. Crowley, Fundamentals of Applied Electro- statics. New York: Teplitz, ed. Paths to Research.

Plenum Press, Maxwell based these equations on previously known results, both experimental and theo- retical. A quick look at these equations shows that we shall be dealing with vector quanti- ties.

It is consequently logical that we spend some time in Part I examining the mathemat- ical tools required for this course. The derivation of eqs. In Part IV, we shall reexamine the equations for time-varying situa- tions and apply them in our study of practical EM devices. We must first learn its rules and tech- niques before we can confidently apply it.

Since most students taking this course have little exposure to vector analysis, considerable attention is given to it in this and the next two chapters. The next chapter builds on this and extends to other coordinate systems. A quantity can be either a scalar or a vector. Indicates sections that may be skipped, explained briefly, or assigned as homework if the text is covered in one semester. Quantities such as time, mass, distance, temperature, entropy, electric potential, and popu- lation are scalars.

A vector is a quantity that has both magnitude and direction. Vector quantities include velocity, force, displacement, and electric field intensity. Another class of physical quantities is called tensors, of which scalars and vectors are special cases. For most of the time, we shall be concerned with scalars and vectors.

## Shepherding a Child's Heart by Tedd Trip

A scalar is represented simply by a letter—e. EM theory is essentially a study of some particular fields. A field is a function that specifies a particular quantity everywhere in a region. If the quantity is scalar or vector , the field is said to be a scalar or vector field. Exam- ples of scalar fields are temperature distribution in a building, sound intensity in a theater, electric potential in a region, and refractive index of a stratified medium.

The gravitational force on a body in space and the velocity of raindrops in the atmosphere are examples of vector fields.

The magnitude of A is a scalar written as A or A. A unit vector aA along A is defined as a vector whose magnitude is unity i. Borisenko and I. Tarapor, Vector and Tensor Analysis with Application. Englewood Cliffs, NJ: Prentice-Hall, Vector Algebra H 1 —-y a b Figure 1.

For example, ax is a dimensionless vector of magnitude one in the direction of the increase of the x-axis. The unit vectors ax, a,,, and az are illustrated in Figure 1. Figure 1. The three basic laws of algebra obeyed by any giveny vectors A, B, and C, are sum- marized as follows: Multiplication of a vector with another vector will be discussed in Section 1.

The position vector r,. The position vector of point P is useful in defining its position in space. The distance vector is ihc displacement from one point to another.

Vector A may depend on point P, however. A vector field is said to be constant or uniform if it does not depend on space variables x, y, and z. Points P and Q are located at 0, 2, 4 and - 3 , 1, 5.

Hence, r PQ -3,-1,1 3.

Find the velocity of the man with respect to the earth. Consider Figure 1. Thus there are two types of vector multiplication: Scalar or dot product: Vector or cross product: Scalar triple product: Vector triple product: Note that dot product obeys the following: Cross Product The cross product of two vectors A ;ind B. The direction of an istaken as the direction of the right thumb when the fingers of the right hand rotate from A toB as shown in Figure 1.

Alternatively, the direction of an is taken as that of theadvance of a right-handed screw as A is turned into B as shown in Figure 1. The vector multiplication of eq. Note that the cross product has the following basic properties: The identities in eqs. It should be noted that in ob- taining an, we have used the right-hand or right-handed screw rule because we want to be consistent with our coordinate system illustrated in Figure 1.

A right-handed coordinate system is one in which the right-hand rule is satisfied: In a left-handed system, we follow the left-hand or left-handed Throughout this book, we shall stick to right-handed coordinate systems. Just as multiplication of two vectors gives a scalar or vector result, multiplication ofthree vectors A, B, and C gives a scalar or vector result depending on how the vectors aremultiplied. Thus we have scalar or vector triple product. The projection can be scalar or vector.

Notice from Figure 1. In fact, our Cartesian repre- sentation of a vector is essentially resolving the vector into three mutually orthogonal com- ponents as in Figure l. We have considered addition, subtraction, and multiplication of vectors. Differentiation and integration of vectors will be considered in Chapter 3. The angle dAB can be found by using either dot product or cross product.Semiconductor Devices Physics and Technology by S.
