Summary  A course on the Maxwell equations, their Lorentz invariance, covariant formulation, and gauge invariance. Applications included classical radiation from time dependent charges and currents, and in particular accelerating charges. 
Course description 
* Electrodynamics: Maxwell's equations, charge, energy and momentum conservation, the electromagnetic potentials, electromagnetic radiation and its generation, electric and magnetic dipole radiation.
* Relativity: Lorentz transformations, 4vectors, relativistic dynamics, the covariant formulation of Maxwell's equations, gauge invariance, magnetism as a relativistic phenomenon, the stressenergy tensor.
* Accelerating charges: covariant Green's functions, the LienardWiechert potential, their associated fields, synchotron radiation, Larmor formula and the AbrahamLorentz equation.
* Action principles: for point particles, scalar fields, vector fields, Noether's theorem, charge and energymomentum conservation, the Yukawa potential, radiation vs matter.

5. understand transport of energy and Poynting vector
6. understand transport of momentum, Maxwell stress tensor and radiation pressure
7. show laws of geometric optics originate with Maxwell's equations at dielectric boundaries
8. calculate reflection and transmission coefficients for waves at dielectric boundaries
9. obtain scalar and vector potential equations in presence of sources
10. understand gauge invariance of Maxwell's equations, decoupling of scalar and vector potential equations in Lorentz gauge and corresponding solutions
11. solve for retarded potentials and electric and magnetic fields for simple problems involving timedependent chargecurrent distributions
12. understand the term radiation zone and derive angular distribution of and power emitted by a dipole
13. write down electromagnetic field tensor in covariant notation
14. derive fully covariant forms of Maxwell equations, Lorentz gauge condition and continuity equation
