Description of the class


The aim of this course is to cover the standard topics of classical electrodynamics in a mathematically sophisticated and conceptually rigorous manner. Electrodynamics is one of the fundamental subjects in Physics because all of the modern physics experiments basically rely on electromagnetism one way or another.

This course will cover a number of fundamental topics in classical electrodynamics, including a brief review of electrostatics and magnetostatics and detailed studies of the characterization, propagation, generation, and scattering of electromagnetic waves, and an introduction to covariant electrodynamics. The course assumes a prior exposure to electrostatics and magnetostatics at the undergraduate level.




Lectures

Monday and Wednesday, 9:00-10:15, PAIS 1160.

Recommended Books

Classical Electrodynamics by J. D. Jackson.
Electrodynamics of Continuous Media by L. Landau and E. Lifshitz

Office hours

Instructor
Mondays and Wednesdays 10:15-11:30, and Wednesdays 15.50-16.50 in PAIS 2232. These are nominal office hours, you are welcome to come into my office at other times too if your questions cannot wait, although I would appreciate if you could send an email announcing your visit. Sometimes, this drop-in approach may not work if I am very busy or your question requires more than just a few minutes, but in that case I will ask you to come back at a later time.

Teaching assistant
The teaching assistant is Sivaprasad Omanakuttan will be available on Tuesday from 14.00 to 15.00 in PAIS 2008 for you to discuss any homework grading issues you may have (please send an email to arrange an appointment).

Grading

The grading in the course will be based on your performance in homework assignments, one midterm exam, and a final exam. The maximum grade will be 100 points, with the following distribution:

  1. Homework: the best (n-1) scores of the n assignments will represent the 20% of the final grade.
  2. Midterm exam: it will represent the 40% of the final grade.
  3. Final exam: it will represent the remaining 40% of the final grade.

The MT exam is tentatively scheduled for March 11, during class time and the final exam will be tentatively held on May 13 (7.30 am).

There will be an optional small project that will provide a maximum of 10 extra points. More details will be given during the semester.

Homework assignments

There will be tentatively 9 assignments during the semester each with 4-7 problems apiece. The assignments will be given throughout the semester and will be posted in the tentative schedule about 7-10 before they are due. Late homework policy: homework returned in the next 24 hours after the due date will be accepted but with 50% penalization. After 24 hours of the due date the corresponding solutions will be posted here.

Problems class

Listed officially as Phyc 551.015 (Wednesdays: 15:00-15.50, Room 1160). This is a very important adjunct to the main lecture class. It will provide you additional practice with solving problems beyond the homework assignments and self study. We will also cover some examples of numerical approaches to solve problems in electrodynamics. Furthermore, the class will also give you a valuable opportunity to bring to my attention your difficulties with any concepts covered in the lecture class so I can address them in a group setting. The problem sheets would be posted here before the problem class. The corresponding solutions will be posted after the class. You will receive credit for the problems class as long as you register and show up for 10 sessions or more.
