## Description:

About the Project

The scope of this project is to develop an OER textbook on Electromagnetics. The book will cover the fundamental concepts in the filed, provide the mathematical backgrouond, explain the physical meaning of the different concepts and provide examples of applications. The goal is to make the connection between the concepts and math with the applications that students find interesting or get to use in their everyday life.

Motivators

Students tend to avoid to buy expensive books. Most “good” electromagnetic books tend to be expensive. For that reason, many students do not follow the books suggested by instructors and many times find parts of the material covered from disparate websites. An OER book, may provide the means for these students to start following a book and going through the material in a more consistent way.

Audience

Anyone who is interested in finding more about applications in electromagnetics.

Licensing

Attribution-NonCommercial-NoDerivatives 4.0 International

Initial more restrictive license to better develop the project. May change in the future

Structure

The book will be structured in four basic units. Each unit will have chapters that focus on the specific concept and applications. The units and the associated chapters will be:

Unit 1. Static Electric Fields

Fundamental Postulates of Electrostatics in Free Space.

Coulomb’s Law

Gauss’s Law and Applications

Electric Potential

Energy Density

Electrostatic Boundary Conditions

Dielectrics in Static Electric Field

Electric Flux Density and Dielectric Constant

Capacitance

Unit 2 Static Magnetic Fields

Fundamental Postulates of Magnetostatics in Free Space

Amperes Circuital Law

Applications

Magnetic Field Intensity and Relative Permeability

Magnetic Boundary Conditions

Magnetic Energy

Unit 3 Time-Varying Fields & Maxwell’s Equations

Faraday’s Law of Electromagnetic Induction

Maxwell’s Equations

Electromagnetic Boundary Conditions

Wave Equations and their Solutions

Time Harmonic Fields

Unit 4 Plane Electromagnetic Waves

Plane Waves in Lossless Media

Plane Waves in Lossy Media

Group Velocity

Flow of Electromagnetic Power & the Poynting Vector

Normal Incidence at a Plane Conducting Boundary

Normal Incidence at a Plane Dielectric Boundary

Normal Incidence at Multiple Dielectric Interfaces

Oblique Incidence at a Plane Dielectric Boundary

There will be an effort to include a collection of publicly available resources that provide visualization of the concepts through videos, presentations and/or application notes.

Timeline

Provide an approximate timeline for the project. This doesn’t have to be comprehensive, or rigid, but an indicator of dates for major milestones (e.g. chapters submitted, peer review complete, beta testing, initial release, etc.)

Kick off June 2021

Unit 1 completion Nov 2021

Unit 2 completion Feb 2022

Unit 3 completion May 2022

Unit 4 completion July 2022

Feedback from students and/or colleagues Aug 2022 Revisions October 2022

How to Get Involved

If you are interested in providing content, exercises, images, application examples with explanation etc., we would be happy to speak with you about it and add you as a contributor. We are also interested in finding peer reviewers for the chapters, which will be available in the Fall 2022 semester. If you would like to provide content or peer review a chapter, please contact Nicholas Madamopoulos

Measures of Success

I will know I have met the goals after students study the book and come to the class with a different mentality, a positive mentality, that even though the material and concepts are considered difficult, the vast number of applications trigger their curiosity and makes them study the material in more depth.
