About

About the course

Course content

Mathematical treatment of electromagnetic and acoustic waves. Transmission line equations. Characteristic impedance. Reflection and transmission coefficients. Waves with harmonic variation. 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.

Learning outcome

Short description:
The subject is aimed at giving the students a good understanding of time-varying scalar and vector fields and a thorough understanding of linear wave propagation. The main part of the course is concerned with electromagnetic fields, however, many of the mathematical ideas and tools for electromagnetic wave propagation are general and the course also addresses wave propagation for mechanical waves. Specifically, the course ends with a basic description of acoustic waves based on the mathematics learned from describing electromagnetic waves.

The subject will teach the students to:

Knowledge:
- understand and use Maxwell's equations in many different types of geometries and materials
- describe wave propagation in transmission lines and waveguides
- understand the physics behind radiation and be able to describe the radiation patterns from basic antenna structures
- derive the basic equations for acoustic wave propagation

Skills:
- combine earlier knowledge from mathematics and physics with new theory for solving practical problems within wave propagation
- the use of computer software (Matlab) for visualization of waves and fields in vacuum, dielectrics and waveguides.
