R-matrix theory of driven electromagnetic cavities
F. Beck, C. Dembowski, A. Heine +1
Resonances of cylindrical symmetric microwave cavities are analyzed in R-matrix theory which transforms the input channel conditions to the output channels. Single and interfering…
Experimental Test of a Trace Formula for a Chaotic Three Dimensional Microwave Cavity
C. Dembowski, B. Dietz, H. -D. Graef +4
We have measured resonance spectra in a superconducting microwave cavity with the shape of a three-dimensional generalized Bunimovich stadium billiard and analyzed their spectral f…
First Experimental Evidence for Chaos-Assisted Tunneling in a Microwave Annular Billiard
C. Dembowski, H. -D. Graef, A. Heine +3
We report on first experimental signatures for chaos-assisted tunneling in a two-dimensional annular billiard. Measurements of microwave spectra from a superconducting cavity with…
Anderson Localization in a String of Microwave Cavities
C. Dembowski, H. -D. Graef, R. Hofferbert +3
The field distributions and eigenfrequencies of a microwave resonator which is composed of 20 identical cells have been measured. With external screws the periodicity of the cavity…
Coupled Microwave Billiards as a Model for Symmetry Breaking
H. Alt, C. I. Barbosa, H. -D. Graef +5
Two superconducting microwave billiards have been electromagnetically coupled in a variable way. The spectrum of the entire system has been measured and the spectral statistics ana…
Correlation-Hole Method for Spectra of Superconducting Microwave Billiards
H. Alt, H. -D. Graef, R. Hofferbert +5
The spectral fluctuation properties of various two- and three-dimensional superconducting billiard systems are investigated by employing the correlation-hole method. It rests on th…
