PHYS3935: Electrodynamics and Optics (Advanced)

The development of electrodynamic field theory laid the foundation on which all of modern physics is built, from relativity to quantum field theory. Its application to electromagnetic waves and optics underpins all of modern telecommunications, but also some of the most delicate physics experiments, from gravitational wave detection to quantum computing. This is a core unit in the physics major, which has three components: electrodynamics lectures, optics lectures, and experimental lab. The advanced unit covers the same concepts as PHYS3035 but with a greater level of challenge and academic rigour, largely in separate lectures. You will apply Mawell's equations to derive properties of electromagnetic waves, the interaction of waves with matter, waveguides, radiation and Gauge transformations. This will lead to optics lectures in which you will investigate aspects of modern optics, using the laser to illustrate the topics covered, in combination with a discussion of the basic optical properties of materials, including the Lorentz model. You will investigate spontaneous and stimulated emission of light, laser rate equations, diffraction, Gaussian beam propagation, anisotropic media and nonlinear optics. You will design your own in-depth experimental investigations into key aspects of electrodynamics, optics, as well as other topics in physics, with expert tutoring.

At the completion of this unit, you should be able to:

  • LO1. demonstrate an understanding of key concepts in two foundation areas of physics - electrodynamics and optics
  • LO2. apply these concepts to develop models, and to solve qualitative and quantitative problems in scientific contexts, using appropriate mathematical and computing techniques as necessary
  • LO3. design experiments to measure specific effects
  • LO4. compare and critique experimental approaches and electrodynamic models
  • LO5. communicate scientific information appropriately, through written work and an oral presentation
  • LO6. analyse a physical problem in electrodynamics and optics and develop a formalism appropriate for solving it
  • LO7. demonstrate a sense of responsibility, ethical behaviour, and independence as a learner and as a scientist.
