Using the equivalence between the quantum-mechanical probability density in aquantum billiard and the Poynting vector in the corresponding microwave system,current distributions were studied in a quantum dot like cavity, as well as ina Robnik billiard with lambda=0.4, and an introduced ferrite cylinder. Spatialauto correlation functions for currents and vorticity were studied and comparedwith predictions from the random-superposition-of-plane-waves hypothesis. Inaddition different types of vortex neighbour spacing distributions weredetermined and compared with theory.Comment: PTP-LaTeX, 10 pages with 6 figures submitted to Progress of Theoretical Physics Supplemen
