For junior/senior-level electricity and magnetism courses. This book is known for its clear, concise and accessible coverage of standard topics in a logical and pedagogically sound order. The Third Edition features a clear, accessible treatment of the fundamentals of electromagnetic theory, providing a sound platform for the exploration of related applications (ac circuits, antennas, transmission lines, plasmas, optics, etc.). Its lean and focused approach employs numerous examples and problems.NEW TO THIS EDITION *NEW - Not a radical revision but rather a fine-tuning of the second edition, building on successful features of the first two editions. *NEW - Every sentence has been reviewed for clarity and precision, and revised as needed, particularly regarding very difficult topics. *NEW - Ambiguous or awkward notation has been changed - for example, the same letter r is no longer used for spherical and cylindrical coordinates and the text now provides a more careful introduction of the script-r notation for the vector from source point to field point. *NEW - Slightly expanded sections on energy, momentum and angular momentum. *NEW - The Helmholtz theory is now covered in an appendix rather in the main body of the text. *NEW - New and revised examples and problems. *NEW - Updated references to accessible current literature for students wishing to explore recent developments in this field. *Friendly, informal style. *Clear focus on basic electromagnetic theory, providing a sound platform for future exploration of related applications (such as ac circuits, antennas, transmission lines, plasmas, optics, etc.). *Large collection of problems: short, highly-focused problems are placed immediately following the relevant text section while longer/more broadly-based problems are at the end of the chapter. *More extensive coverage of radiation theory than most texts at this level.
