Textbook:   “Applied Electromagnetism”, L.C. Shen and J.A. Kong

Course Description:

Static and time varying electric and magnetic fields, Maxwell’s equations in differential and  integral form, uniform plane waves, transmission lines, wave guides, and antennas.

Objectives:

To understand the basic concepts of electromagnetics and their application to other branches of electrical engineering.  Develop electromagnetic problem solving skills and show applications in areas outside electrical engineering such as bioengineering, remote sensing, geology, astronomy, …

Outcomes:

Students will learn how to solve basic ElectroMagnetic (EM) problems and how EM techniques can be used to solve problems in other fields.  They will learn how EM relates to modern electrical engineering devices and systems.  They will learn how to manipulate EM lab equipment.
