Aim
The course gives an understanding of the physics of transmission lines, waveguides, and optical fibres. It gives an introduction to the analytical and numerical methods that are used in this area. The students get skills in measurements with network analyser. They also get experience in treating extensive applied problems and projects.

Knowledge and understanding
For a passing grade the student must

• master the most common mathematical and numerical methods for wave propagation along guiding structures

• have elementary knowledge in measurements at high frequencies

Skills and abilities
For a passing grade the student must

• be able to apply the elementary theory for transmission lines

• be able to use the method of separation of variables for wave propagation in waveguides and optical fibres

• know how to apply the finite element method to waveguides and optical fibres

• know how to use the network analyser for measurements at high frequencies

• know how to apply commercial programs for the finite element method to wave propagation problems

Judgement and approach
For a passing grade the student must

• be able to evaluate different types of systems for communication with guiding structures

• determine which analytical, numerical, and experimental methods that are suitable for analysing a system

Contents
Transmission lines, Smith chart, network analyser, S-matrix, rectangular and circular wave guides, TE- and TM-modes, resonance cavities, optical fibres, optical components in optronics, periodic structures and the finite element method.
