Physics 319 — Advanced Electricity and Magnetism

Objectives and Goals

Overview:
Physics 319 is the second semester of the department's one year sequence on Classical Electrodynamics for graduate students. The main topics of this course are the special relativity, relativistic mechanics, radiation by moving charges, collision and scattering of charged particles, and other special topics on electro-magnetic fields and charged particles.
Related courses and prerequisites:
Phys 318 or satisfactory performance on a placement exam.
Objectives:
Part 1: Special Relativity and Relativistic Mechanics
We will cover the principle of special relativity and relativistic mechanics to create a solid basis for the invariant form of classical electrodynamics. We will emphasize the use of four dimensional tensors in the relativistic mechanics. We will finish this part with the example of elastic collision of particles.

Part 2: Charged Particles in Electromagnetic Fields
The main topics of this part of the course include four potential of a field, electromagnetic field tensors, Lorentz transformation of the field, gauge invariance, and Maxwell equations expressed in the covariant form. We will emphasize the use of least action principle, Lagrangian, and Hamiltonian for describing the relativistic charged particle motion in the external fields and for electromagnetic fields. We are hopeful that Parts 1 and 2 will lay down the foundation for mastering the relativistic electrodynamics.

Part 3: Radiation by Moving Charges
Liénard-Wiechert potentials and radiation theory are studied as core examples of applying the relativistic electrodynamics to real physics problems. We will learn how and why accelerated charges radiate. We will cover some interesting topics, including spatial and spectral properties of charged particle radiation using examples of particle radiation in bending magnets, undulators, and wigglers.

Part 4: More Topics
We plan to cover topics of collisions, energy loss and scattering of charged particles by focusing on Cherenkov radiation and transition radiation.

Part 5: Other Physics Topics
If we complete the ambitious curriculum above, we may discuss other selected topics in plasma physics, scattering, physical media, optics, and others. You are welcome to sign up for a research project related to one of these special topics.
