Thoroughly updated and revised, this third edition of Sadiku's Elements of Electromagnetics is designed for the standard sophomore/junior level electromagnetics course taught in departments of electrical engineering. It takes a two-semester approach to fundamental concepts and applications in electromagnetics beginning with vecotr analysis-which is then applied throughout the text. A balanced presentation of time-varying fields and static fields prepares students for employment in today's industrial and manufacturing sectors. Mathematical theorems are treated separately from physical concepts. Students, therefore, do not need to review any more mathematics than their level of proficiency requires. Sadiku is well-known for his excellent pedagogy, and this edition refines his approach even further. Student-oriented pedagogy comprises: chapter introductions showing how the forthcoming material relates to the previous chapter, summaries, boxed formulas, and multiple choice review questions with answers allowing students to gauge their comprehension. Many new problems have been added throughout the text, as well as a new chapter on ''Modern Topics'' covering microwaves, electromagnetic interference and compatability, and optical fibers.
This book is appropriate for sophomore/junior level students in electrical engineering. It will also be accompanied by a Solutions Manual, available free to adopters of the main text.
Presents EM concepts in a clearer and more interesting manner than any other text on the market
Covers vector analysis at the outset and applies it gradually -- avoiding the frequent interruptions that occur when mathematical background is interspersed throughout the ext
Features in each chapter are a brief introduction, numerous solved examples, review questions (multiple choice, not open-ended), and problems graded into three levels of difficulty
Richly illustrated with boxed formulas, 130 illustrated examples and over 600 figures
