Contents:

The aim of this lecture is to give an introduction into the physics and technical application of transmission media and to introduce the principles of the numerical simulation of such applications. In the first part, the core concepts of electrodynamic wave propagation (Maxwell's Equations, plane wave propagation, reflection, scattering and diffraction, elementary antennas) are discussed. Finally, an overview is given over the most common practical implementations of wave guiding structures and other microwave components (TEM and non-TEM waveguides, cavity resonators, splitters, circulators, etc.) In the second part, the most common numerical methods are presented together with their practical application to the simulation of real devices.

• Electromagnetic waves: propagation in free space, polarization, reflection/refraction
• Numerical solution of electromagnetic field problems – Space discretization with surface and volume meshes; Main numerical algorithms for discrete local approximation of Maxwell’s equations; Finite Integration Technique; Time and frequency domain solution methods; Stability, convergence.
