Abstract: | The signatures of wave functions in open cylindrical microwave billiards are investigated. The wave functions are obtained
by means of a transmission measurement from an attached lead to a probe antenna inside the billiard. One can deduce complex
wave functions and current densities of the system from the measurement. We investigate distributions and correlations of
wave functions, currents and other quantities and compare this results with predictions from the random plane wave approach.
Vortices and saddles are created and annihilated as a function of frequency and show a rich dynamic. Additionally we investigate
nodal domains of the real and imaginary part of the wave function, their relation to the phase rigidity, and its parametric
dependance on global phase shifts. |
