Elektrodynamik

**Valid from:** Spring 2018**Decided by:** Professor Thomas Johansson**Date of establishment:** 2018-08-24

**Division:** Electrical and Information Technology**Course type:** Course given jointly for second and third cycle**The course is also given at second-cycle level with course code:** EITN80**Teaching language:** English

The course provides a deep and broad understanding of electromagnetic theory. It complements the basic course in key areas related to electromagnetic waves and the interaction between moving charged particles and electromagnetic fields. It also gives the relativistic description of electrodynamics, with the aim of providing a basic understanding of accelerator physics. The course discusses techniques for measurements of electromagnetic fields in experiment and technology.
