Recommended Reading :
placed on reserve at the Science and Engineering Library (SEL)
- L.D. Landau, E.M. Lifshitz - The Classical Theory of Fields: Volume 2
- L.D. Landau, E.M. Lifshitz, L.P. Pitaevskii -
Electrodynamics of Continuous Media: Volume 8
- D.J. Griffiths - Introduction to Electrodynamics (this is a useful book to refresh your memory, but it does not cover all the material we will be talking about in class)
Lecture Notes:
These are the notes from when I taught this class 2 years ago, they will be updated as we go through the course. The notes are sorted according to chapters in Jackson's textbook.

Homework Assignments:
Homeworks are due at 11:59 pm on the due date. Please put them in the grader's mailbox in PRB or give them to me in class (or slide them under my office door if the other options are not available). Homeworks submitted late are penalized -10 pts. The cutoff for late HW submissions is 5 pm on the day after the HW is due. (Solutions are password
protected, they are for the use of OSU students and faculty only, please write to me if you are
interested in accessing them.) Each problem is worth 10 pts unless stated otherwise.
- HW 1 (due Wednesday, January 16) Jackson problems 6.1, 6.9 (ignore the last question about epsilon and mu being functions of position), 6.10, 6.4 (problem 6.4 is worth 20 pts) [hint: Ohm's law states that in a conductor J = sigma E; in the rest frame of the sphere J=0; you will also need the Galilean transformation for the electric field between two different frames] -- Solution 1
- HW 2 MODIFIED: (due Wednesday, January 23) Jackson Problems 7.2, 7.6 (a) and one more problem -- Solution 2
- HW 3 (due Wednesday, January 30) Jackson problems 7.4, 7.13 (a), 7.16 -- Solution 3
- Optional HW on Residues (due Wednesday, February 6, the whole HW is worth 10 pts of extra credit, problems 1-6 are worth 1 point each, problems 7,8 are worth 2 points each)
- HW 4 (by popular demand and due to me falling behind in lectures it is now due Friday, February 8 at 5 pm sharp) -- Solution 4
- HW 5 (due Wednesday, February 27) Jackson Problems 9.2, 9.3 (hint: you will only need the electric dipole component), 9.7 (hint: repeat the steps done in class Fourier-transforming all quantities into omega-space first, and then undo the Fourier transform), 9.16 (omit radiation resistance in part (b)) (hint: use Eq. (9.8) in Jackson; see also Ch. 9.4 A) -- Solution 5
- HW 6 (due Friday, March 7 at 5 pm) By popular demand, problem 10.4 in this HW is optional. -- Solution 6
Exams: Midterm - Wednesday, February 13, 2008, 8:30 - 10:18 am, McPherson 2019 Final - Tuesday, March 11, 2008, 9:30 - 11:18 am, Dreese Lab, room 0705
Grading: 25% HW, 30% Midterm, 45% Final
