Module B is unofficially divided into two sub-modules, the first dedicated to teaching classical electrodynamics, the second to Einstein's special (or restricted) theory of relativity. In particular, the specific contents can be summarized as follows: CLASSICAL ELECTRODYNAMICS - ELECTROMAGNETIC INDUCTION Static Maxwell equations, Faraday-Neumann-Lenz law, applications of Faraday's law, self-induction, RL circuits, electric oscillations, Maxwell equations - ELECTROMAGNETIC WAVES Maxwell's equations without sources: plane waves, spherical waves - RADIATION FROM CHARGES IN MOTION Maxwell equations with sources: potentials, delayed potentials, point charge, dipole approximation, spectrum of electromagnetic waves, expansion in multipoles - RADIATION-MATTER INTERACTION Diffusion, chromatic dispersion in a dielectric, absorption of radiation, free electrons. SPECIAL RELATIVITY - FORMULATION OF THE THEORY Minkowski space-time, Lorentz transformations, composition of velocity, relativistic acceleration, paradoxes in RS - RELATIVISTIC MECHANICS Generalization of Newtonian mechanics, massless particles, example: charge in an EM field, example: particle in central potential -VECTOR AND TENSOR ALGEBRA Four-vector, tensors, 1-forms, metric tensor, covariant formulation of mechanics, example: Compton effect, example: energy-momentum tensor - COVARIANT ELECTRODYNAMICS Principle of least action and electromagnetic tensor, covariant formulation of eqz. Maxwell's, transformation of fields, radiation from relativistic charges
