Elements of Electromagnetics

Description

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.

New to this Edition

• Five new "Application Notes" sections, designed to explain the real-world connections to the concepts discussed in the text
• A revised "Math Assessment" test for instructors to gauge their students' mathematical knowledge and preparedness for the course
• An abundance of new and updated end-of-chapter problems
