Course Organization


This is an intense one semester graduate course in Classical Electrodynamics. We begin with a very brief review of electrostatics and magnetostatics where the required special functions and Green function techniques are introduced. After this introduction, we describe Faraday's Law and the quasi-static approximation to the Maxwell system. Following these developments we study the propagation of light in media, and categorize the response functions of typical materials. Subsequently we describe diffractive and scattering phenomena with partially coherent light. Then we discuss multipole radiation, placing classical electrodynamics within the context of special relativity. This formalism is used to study radiation in various contexts. The course will emphasize problem solving.

The structure and tentative order of the course is the following

  1. Electrostatics:

  2. Electric fields in matter:

  3. Magnetostatics:

  4. Magnetism and magnetic fields in matter:

  5. The Maxwell equations and the quasistatic approximation:

  6. Propagation of waves in media and at interfaces:

  7. Multipole radiation, and radiation by slow charges:

  8. Relativity, covariance, and electrodynamics:

  9. Radiation by fast charges:

  10. Scattering of radiation and diffraction:

The following is a portrait of Faraday. May his memory inspire young experimentalists, and young theorists to listen to them.

Class Meetings

The course consists of three lecture hours and two hour recitation. Recitations will be used to discuss problems.

Office Hours

Please feel free to contact me at anytime. My official office hours are,

Final Exam

The final exam is on Tuesday, December 17 from 2:15--5:00 p.m in P130.

Grade Determination

The grading will be based roughly on the following table. I reserve the right to change these proportions (within reasonable limits) as the course progresses. My intent of course is to follow these guidelines.

Homework 25%
Midterm Exam 35%
Final Exam 40%

Homeworks will be assigned weekly, and will be collected ** at the start of class ** . Homework handed in within a day after the due date/time will by given a 5% penalty. After this, late homeworks will be penalized at 10% per day.

The Book and Resources

The required book for the course is

  1. Modern Electrodynamics by Andrew Zangwill.

Some other books which I used when preparing the course are:

  1. A good source of problems is: Classical Electrodynamics by John David Jackson
  2. A interesting perspective on the subject is: Classical Electrodynamics by Julian Schwinger, Lester Deraad, Kimball Milton, Wu-yang Tsai.
  3. I have found: Methods of Theoretical Physics, Part I and II by Morse and Freshbach an invaluable, enjoyable, and surprisingly readable reference over the years.
  4. Professor Likharev's lecture notes

Academic Integrity

Each student must pursue his or her academic goals honestly and be personally accountable for all submitted work. Representing another person's work as your own is always wrong. Faculty are required to report any suspected instances of academic dishonesty to the Academic Judiciary. Faculty in the Health Sciences Center (School of Health Technology & Management, Nursing, Social Welfare, Dental Medicine) and School of Medicine are required to follow their school-specific procedures. For more comprehensive information on academic integrity, including categories of academic dishonesty, please refer to the academic judiciary website at http://www.stonybrook.edu/uaa/academicjudiciary/

Religious Holidays

If the schedule of homeworks, exams or other assignments is in conflict with your religion's Holidays, please let me know in an email by the end of the first week of instructions and I will do my best to accommodate your needs. Please note that I cannot make changes in the course schedule after the first week of classes. No consideration will be made if someone approaches me in this matter at a time close to the due date or the exam date.

Americans with Disabilities Act

If you have a physical, psychological, medical or learning disability that may impact your course work, please contact Disability Support Services, ECC (Educational Communications Center) Building, room128, (631) 632-6748. They will determine with you what accommodations, if any, are necessary and appropriate. All information and documentation is confidential.

Students who require assistance during emergency evacuation are encouraged to discuss their needs with their professors and Disability Support Services.

Critical Incident Management

Stony Brook University expects students to respect the rights, privileges, and property of other people. Faculty are required to report to the Office of Judicial Affairs any disruptive behavior that interrupts their ability to teach, compromises the safety of the learning environment, or inhibits students' ability to learn.
