Experimental resonance spectra and field distributions of a dielectric cube — •Marco Masi, Barbara Dietz, Maksim Miski-Oglu, and Achim Richter — Institut für Kernphysik, TU Darmstadt, 64289 Darmstadt, Germany

In the frame of a project which envisages to extend the experimental study from 2D to 3D dielectric microwave resonators, we present the measurement results for a 3D alumina cube resonator. The aim is the understanding of its spectral properties and its electromagnetic field distributions. These are different from those of a 2D flat dielectric microwave resonator since all polarizations have to be taken into account. Its resonance frequencies, the length spectrum of its corresponding classical periodic orbits, the wave vector distribution, the mode symmetry classes, and the polarization states are investigated. A central question is the existence of superscars in 3D resonant structures, and more generally the validity of semiclassical approximations in 3D resonant structures.
