Using a vectors-first approach, Elements of Electromagnetics, Seventh Edition, covers electrostatics, magnetostatics, fields, waves, and applications like transmission lines, waveguides, and antennas. The text also provides a balanced presentation of time-varying and static fields, preparing students for employment in today's industrial and manufacturing sectors.Streamlined to facilitate student understanding, Elements of
Electromagnetics features worked examples in every chapter that explain how to use the theory presented in the text to solve different kinds of problems. It also covers numerical methods, including MATLAB and vector
analysis, to help students analyze situations that they are likely to encounter in industry practice.
Rezensionen / Stimmen
"This is one of the best electromagnetics textbooks on the market. With its understandable language and strong approach, Elements of Electromagnetics is almost perfect."--Lili H. Tabrizi, California State University, Los Angeles
"Well-written and easy to follow, with an excellent balance of rigor, ease, and clarity. This text has lots of practice problems and a wonderful collection of application notes."--Sudarshan Nelatury, Pennsylvania State University, Erie
