Dispersion, phase and group velocity. Electromagnetic and acoustic waves in free space. Planar, cylindrical and spherical waves. Field equations in waveguides. TEM, TE and TM waves. Antennas.

Knowledge: The candidate has - good knowledge of Maxwell's equations - good knowledge of wave propagation in transmission and waveguides - good understanding of time-varying scales and vector fields, as well as a basic understanding of linear wave propagation - general knowledge of the physics of radiation - good knowledge of basic equations for acoustic wave propagation Skills: The candidate can - apply Maxwell's equations to many relevant geometries and materials - combine previously acquired knowledge and skills in mathematics and physics with new theory to solve practical issues within wave propagation - derive and apply basic equations for acoustic wave propagation - describe fields from basic antenna structures - use data tools (Matlab) for visualization of waves and vector fields in free space and waveguides. General knowledge: The candidate can - work individually to solve problems (e.g. tutorials) - use the mathematical tools developed in the course on other types of fields and waves in engineering and physics courses

Lectures and exercises. 12 calculation and/or laboratory exercises are given. Students must have a minimum of 8 passes to be allowed to sit for the exam.
