Summary

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, preparingstudents 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 analyzesituations 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 toadopters.
