The students have insight into the physical phenomena of electromagnetic radiation and wave propagation. At the end of the lecture, they are able to describe electromagnetic waves in free space and inside waveguides as well as the interaction of electromagnetic waves with matter.
The lecture with integrated exercises covers fundamental phenomena of electromagnetic wave propagation. Starting from Maxwell’s equations, the wave propagation in free space and inside of waveguides is discussed. This comprises: hollow metallic waveguides in rectangular and circular geometries as well as dielectric waveguides such as fibers. Furthermore coaxial-cables as well as classical waveguide structures that are commonly used in radio-frequencies are considered. Afterwards, the lecture discusses basic principles of electromagnetic radiation using antenna structures. For this purpose, a collection of basic antenna architectures is presented. The obtained insights are applied to practical problems, such as the link-budget calculation of mobile communication systems or radar reflections from targets.
The lecture covers the following topics:
- Maxwell’s equations and the wave equation
- Propagation of electromagnetic waves
- Reflection / Transmission at material boundaries and their applications
- Electromagnetic waves in waveguides
- Dielectric waveguides
- TEM- and quasi-TEM waveguides
- Electromagnetic radiation
- Antennas and farfield discussions
- Link budget
- Radar equation
