Summary of Intended Learning Outcomes
On completion of the course the student should be able to:
1. understand origin of Maxwell's equations in magnetic and dielectric media
2. write down Maxwell's equations in linear, isotropic, homogeneous media
3. derive continuity conditions on electromagnetic fields at boundaries
4. derive electromagnetic wave solutions and propagation in dielectric and other media
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
15. obtain Lorentz transformations for electric and magnetic fields and apply to simple cases
16. show the stressenergymomentum tensor components are energy density, Poynting vector and Maxwell stress tensor
17. derive LienardWiechert potentials for a moving point charge
18. derive corresponding electric and magnetic fields
19. show that acceleration of the charge gives electromagnetic radiation
20. apply to cases of charges: slowly accelerating at low velocities; undergoing acceleration collinear with velocity, in a circular orbit (synchrotron radiation).
