Electromagnetics (Volume 1)

Free online at: https://doi.org/10.21061/electromagnetics-vol-1 Electromagnetics Volume 1 by Steven W. Ellingson is a 225-page, peer-reviewed open educational resource (licensed CC BY-SA 4.0) intended for electrical engineering students in the third year of a bachelor of science degree program. It is intended as a primary textbook for a one-semester first course in undergraduate engineering electromagnetics and covers the following topics: electric and magnetic fields; electromagnetic properties of materials; electromagnetic waves; and devices that operate according to associated electromagnetic principles including resistors, capacitors, inductors, transformers, generators, and transmission lines. The book employs the “transmission lines first” approach in which transmission lines are introduced using a lumped-element equivalent circuit model for a differential length of transmission line, leading to one-dimensional wage equations for voltage and current. A free and openly-licensed PDF, problem sets & solutions, editable LaTeX source files, and information for the book’s community portal and listserv are available at: https://doi.org/10.21061/electromagnetics-vol-1. This textbook is part of the Open Electromagnetics Project led by Steven W. Ellingson at Virginia Tech. The goal of the project is to create no-cost openly-licensed content for courses in undergraduate engineering electromagnetics. The project is motivated by two things: lowering learning material costs for students and giving faculty the freedom to adopt, modify, and improve their educational resources.
