Course Information

Course Description

This course provides a background in engineering electromagnetics required for more advanced courses in the field. Topics include vector calculus, Poisson's and Laplace's equations, Vector potentials, Green's functions, magnetostatics, and magnetic and dielectric materials, Maxwell's equations, plane wave propagation and polarization, reflection and refraction at a plane boundary, frequency dependent susceptibility functions, transmission lines, waveguides, and simple antennas. Practical examples are used throughout the course.

Course Goal

            To establish a basic background concerning electromagnetic theory necessary for graduate level courses in electrical engineering. The course is intended to bridge the gap created when a student takes only one course in engineering electromagnetics in their undergraduate program.  The course can also serve as a refresher course for students who have been away from the topic for a long time.

Course Objectives

  • Review basic vector algebra and vector calculus necessary for course.

  • Cover/review electro and magneto-statics.

  • Cover time varying fields and Maxwell's equations.  Students will solve the wave equation and use plane waves to represent solutions.

  • Be able to solve problems involving electromagnetic propagation, waveguides and antennas
