The Course

In fall 2016, as part of my UofT M.Eng (course based engineering master’s), I took Electromagnetic Theory (ECE1228H), and have and have PDF notes for that course available (redacted: 183 pages, full version 256 pages).  You may contact me for the full version if you are not taking the course, and don’t intend to.

This course was taught by Prof. M. Mojahedi.

The official course description at the time was:

Fundamentals: Maxwell’s equations, constitutive relations and boundary conditions, wave polarization. Field representations: potentials, Green’s functions and integral equations. Theorems and concepts: duality, uniqueness, images, equivalence, reciprocity and Babinet’s principles. Plane, cylindrical and spherical waves and waveguides. radiation and scattering.

New material in this course was limited to:

  • dispersion relations.
  • Druid-Lorentz model
  • quadropole moments
  • magnetic moments, magnetostatic force, and torque (mentioned in class without details, but studied from Jackson)
  • matrix representation of transmission and reflection through multiple interfaces

Mathematica notebooks associated with this course are also available.

Review of this course.

This course, despite being offered as a grad course, turned out to be largely an introductory course, and was very disappointing. I’d seen fundamentals in the course description, but assumed that this would be a more in depth attack on those fundamentals. In particular, I mistakenly assumed this would be on par with phy1510, the grad physics electromagnetism course, which also covers fundamentals, and is known as one of the most difficult grad physics courses.

Phy1510 is the electromagnetism course I really wanted to take, but I felt forced to take this one to satisfy the M.Eng graduation requirements (a quota of ECE courses was required.)   If I’d been sensible, I wouldn’t have wasted so much time and money on this sub-par ECE electromagnetism course (which cost me $2500 in part time grad student fees).   I definitely did not get my money’s worth out of this course!  As it turned out, I was disappointed in almost all the ECE courses I took — the only exception was multiphysics modelling, taught by Prof Triverio.  In contrast, I was not disappointed in any of the grad physics courses I took, all of which were superb.

I did not think that this course was taught badly.  However, spending that much time on review has no place in a graduate electrical engineering (electromagnetism) program!
