In fall 2016, as part of my UofT M.Eng (course based engineering master’s), I took Electromagnetic Theory (ECE1228H), taught by Prof. M. Mojahedi. My notes for that class (redacted: 187 pages, full version 258 pages) are available in the following forms:
- For free as a pdf,
- As an e-book on leanpub. This is a set your own price e-book service that offers a reader forum for purchasers, and automatic update distribution,
- As latex sources (see below).
The redacted version publicly available omits various assigned problems. Feel free to contact me for the full version if you are not taking the course (and don’t intend to.)
I have unpublished the paperback version of these notes, as I’m not certain they are worth purchasing, and don’t want people to waste their money. If there is demand I can make it available for purchase again, but until then it will show as out of print in the amazon listings.
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 (for me) 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, which I found 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.
I did not think that this course was taught badly. However, I felt that spending that much time on review had no place in a graduate electrical engineering (electromagnetism) program. Professor Mojahedi says that he has been working on expanding the scope of the course considerably, so by now, this course may be considerably different than it was when I took it.
