Learning outcomes

On completion of the course the student shall be able to:


  • interpret the deeper meaning of the Maxwellian field equations and account for their symmetry and transformation properties, domain of validity, and limitations

  • formulate and solve electromagnetic problems with the help of electrodynamic potentials and superpotentials, and make a detailed account for gauge transformations and their use

  • master the technique of deriving and evaluating formulae for the electromagnetic fields from very general charge and current distributions

  • calculate the electromagnetic radiation from radiating systems (aerials, localised charge and current distributions) at rest

  • calculate the electromagnetic radiation from localised charges which move arbitrarily in time and space, taking into account retardation effects. Account for the underlying approximations and assumptions

  • formulate and solve electrodynamic problems in relativistically covariant form in four-dimensional space-time

  • formulate self-consistent models for the interaction between matter and electromagnetic fields in relativistically covariant Lagrange and Hamilton formalism

  • be familiar with some elementary phenomena and concepts in quantum electrodynamics
