Preface Electromagnetics Third Edition :
This is the third edition of our book Electromagnetics. It is intended as a text for use by engineering graduate students in a first-year sequence where the basic concepts learned as undergraduates are solidified and a conceptual foundation is established for future work in research. It should also prove useful for practicing engineers who wish to improve their understanding of the principles of electromagnetics, or brush up on those fundamentals that have become cloudy with the passage of time.
The assumed background of the reader is limited to standard undergraduate topics in physics and mathematics. These include complex arithmetic, vector analysis, ordinary differential equations, and certain topics normally covered in a “signals and systems” course (e.g., convolution and the Fourier transform). Further analytical tools, such as contour integration, dyadic analysis, and separation of variables, are covered in a selfcontained mathematical appendix.
The organization of the book, as with the second edition, is in seven chapters. In Chapter 1 we present essential background on the field concept, as well as information related specifically to the electromagnetic field and its sources. Chapter 2 is concerned with a presentation of Maxwell’s theory of electromagnetism. Here attention is given to several useful forms of Maxwell’s equations, the nature of the four field quantities and of the postulate in general, some fundamental theorems, and the wave nature of the timevarying field. The electrostatic and magnetostatic cases are treated in Chapter 3, and an introduction to quasistatics is provided. In Chapter 4 we cover the representation of the field in the frequency domains: both temporal and spatial. The behavior of common engineering materials is also given some attention.
The use of potential functions is discussed in Chapter 5, along with other field decompositions including the solenoidal–lamellar, transverse–longitudinal, and TE–TM types. In Chapter 6 we present the powerful integral solution to Maxwell’s equations by the method of Stratton and Chu. Finally, in Chapter 7 we provide introductory coverage of integral equations and discuss how they may be used to solve a variety of problems in electromagnetics, including several classic problems in radiation and scattering. A main mathematical appendix near the end of the book contains brief but sufficient treatments of Fourier analysis, vector transport theorems, complex-plane integration, dyadic analysis, and boundary value problems. Several subsidiary appendices provide useful tables of identities, transforms, and so on.
