Symmetries and tunability are of fundamental importance in wave scattering control, but
symmetries are often obvious upon visual inspection, which constitutes a significant …

We report on the realization of a graphene billiard with a fourfold rotational symmetry, which
has the shape of a billiard with chaotic classical dynamics. The eigenstates are separated …

The statistical properties of wave chaotic systems of varying dimensionalities and
realizations have been studied extensively. These systems are commonly characterized by …

We report on high-precision measurements that were performed with superconducting
waveguide networks with the geometry of a tetrahedral and a honeycomb graph. They …

The propagation of wave trains resulting from a local external trigger inside a network
described by a metric graph is analyzed using quantum graph theory. The external trigger is …

Working in analogy with topological insulators in condensed matter, photonic topological
insulators (PTI) have been experimentally realized, and protected electromagnetic edge …

We investigate the fluctuation properties in the eigenfrequency spectra of flat cylindrical
microwave cavities that are homogeneously filled with magnetized ferrite. These studies are …

In the thesis, I present experimental results on microwave networks and reverberation
chambers. The general description is based on scattering theory, describing the reflection …
