Learning outcomes

After successful completion of the course, students are able to visualize electromagnetic waves on transmission lines and in free space and are able to select a suitable transmission line for different kinds of radio frequency signals. Finally, the students are familiar with the problems and natural limits of wave propagation and antennas.

 

Subject of course

General characterization of electromagnetic waves, including repetition of basics: wave vector, field pattern, wave impedance, polarization, boundary conditions, solutions of wave equations in Cartesian coordinate systems, plane waves. Specific examples of some important lines and the waves they propagate: parallel plate, surface waves, dielectric waveguides, microstrip lines. Metallic waveguides (including resonators). Propagation of electromagnetic waves in free-space (radio links, radar) and at interfaces (reflection, scattering, refraction, diffraction). Mobile communication propagation (fast/slow and selective/flat fading, time dispersion and intersymbol interference, description of multi-path propagation with deterministic and stochastic methods). Electrical charcterization of antennas by antenna pattern, gain, polarization, impedance, bandwidth. Far field and near field, basics of reciprocity.

Please note, this lecture is given in German only!

Teaching methods

The theory of electromagnetic waves and antennas is supported by exemplary problems, by hardware items ("things of the week") to touch and feel, and an introduction into the software package EZNEC which allows the numerical modelling of simple antennas. An optional experiment can be carried out at home to verify the law of refraction.

Examination modalities

The exam has a writen and oral part. Optionally, two additional tasks (one is experimental, the other is a simulation) can be accomplished which give add-on points. 

You may not use any aids to answer the 10 theory questions in the written part.
As soon as you have finished, you will hand in the theory part of the exam and you will receive the calculation problems. 
For the solution of the calculation exercises you are only allowed to use the formulary which is enclosed with the exam (and which has to be handed in after the exam). 
Neither the script nor handwritten notes are allowed! 
Graphical calculators and smartphones are also not allowed!

Previous knowledge

This course builds on the knowledge of complex AC calculus for harmonic processes, i.e., those occurring at a single frequency. We use Maxwell's equations in differential form to describe electromagnetic fields. The wave propagation lecture builds on the terms and concepts you learned in the electrodynamics lecture.
