# Elektrodynamik Electrodynamics

## EITN80, 7,5 credits, A (Second Cycle)

Valid for: 2018/19
Decided by: PLED E
Date of Decision: 2018-04-05

## General Information

Elective for: E4-fh, F4, F4-f, F4-hn, F4-aft
Language of instruction: The course will be given in English on demand

## Aim

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.
