Course detail

Electrodynamics and Special Theory of Relativity

FSI-TDEAcad. year: 2017/2018

The course represents the second part of the basic course of theoretical physics. It is concerned with principles of the electromagnetic field theory and the description using Maxwell's equations. Conservation laws of energy and of quantity of motion are derived, field potentials are introduced and electrostatic, magnetostatic and quasistationary fields are described. A great attention is paid to spreading of electromagnetic waves in diverse environments and also to the behaviour of the field at the interface between two environments. At the end of the course the motion of charged particles in electromagnetic fields, principles of the special theory of relativity and invariance of Maxwell equations under the Lorentz transformation are explained.
