Course description and aims

This course deals with advanced topics in electromagnetism. Based on the Maxwell equations, I discuss their solution in vacuum, propagation, radiation and scattering of electromagnetic waves. I also discuss special relativity and manifest Lorentz covariant formulation of electrodynamics. The relativistic motion of a charged particle in an electromagnetic field and radiation from an accelerated charged particle are explained.
Physics of electromagnetic fields is a foundation of physics and modern technology. The principle of relativity and fields are important subjects which play an important role in understanding modern physics. The aim of this course is to get basic concepts in electrodynamics and apply them to various problems starting from the Maxwell equations.

Student learning outcomes

You will be able to understand the basics and applications of the Maxwell equations by many examples. Especially an electromagnetic wave in vacuum, and its propagation, radiation and scattering are mainly focused on. You will also understand how special relativity is important in electrodynamics. You will also be able to understand the motion of a charged particle and radiation from an accelerated source.
