This course will cover the fundamentals of Electromagnetics, or the basic laws and rules that underlie much of the rest of electrical engineering. Much of what the course covers spans a fuzzy boundary between physics and electrical engineering and for this reason may be perceived as more mathematically intensive than many other engineering courses. However the ideas that underlie Electromagnetics are relatively simple, and this course will try to explore the underlying ideas.
The course is divided into four major themes:
- How do wires behave at high frequencies? Why wires and electrical circuits don’t behave
- The way we expect at higher frequencies. How engineers get signals from one place to another on wires and some of the issues to consider when you need to do so.
- What is Electricity and Magnetism? This section explores the properties of electrical harges and tries to answer the question of where magnetism comes from. More stage setting through moving electric charges and the forces they exert.
- How does energy move through free space? Understanding how signals (i.e. energy) can move through space and materials without wires to carry. How to make simple predictions about how signals propagate.
- How to we couple energy from circuits in to and from free space? How we can build simple devices to couple electrical signals from wired circuits into free space and capture signals that are propagating through free space?
Project Description: Create 3, 1-2 minute videos . The first video was on transmission lines, the second on electro- or magneto-statics, while the third video covered Maxwell’s equations and waves. To ensure that students utilized multiple representations, they were required to represent the formula in at least four of these ways: a formula or set of equations, a written definition or description, an algorithmic construct like a flow chart or pseudocode that explains how the formula operates, a diagram (e.g. a schematic diagram), a graph or animation, or a physical device(s) or phenomena that uses the formula.

Learning Goals:
The learning objectives for this course include three basic types of learning: knowledge of facts and concepts, the ability to do skills and procedures, and attitudes and your own knowledge of knowing (metacognition). There are specific learning outcomes for each of these categories that are given in three tables at the end of the syllabus.
Learning Outcomes
This course has the following learning outcomes for a basic understanding of electromagnetics that form a representative set of what students should be able to do by the end of the course. These may not all be covered, change during the course, or be modified depending on formative evaluation performed during the class.
