Electrodynamics
Elektrodynamik

EITN80F, 7.5 credits

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

General Information

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

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.

Goals

• determine the electromagnetic fields caused by accelerating charged particles
• understand the principles of particle accelerators
• determine the electromagnetic fields that can propagate in various types of metallic waveguides
• understand the concepts waveguide, phase and group velocity and cut-off frequency of waveguides
• to determine the electromagnetic fields that can exist in the resonant cavities
• understand different methods for measurements of electromagnetic fields and the physical limitations of these methods

Competences and Skills

For a passing grade the doctoral student must

• to assess the mathematical and numerical methods suitable for the analysis of various types of time-dependent electromagnetic problems
