U. Dorr et al., SCARRED AND CHAOTIC FIELD DISTRIBUTIONS IN A 3-DIMENSIONAL SINAI-MICROWAVE RESONATOR, Physical review letters, 80(5), 1998, pp. 1030-1033
For about 200 eigenfrequencies of a Sinai-shaped three-dimensional mic
rowave resonator electromag netic field distributions were mapped by m
easuring the eigenfrequency shift Delta nu as a function of the positi
on of a spherical perturbing bead. Both regular and chaotic field patt
erns were found. For the chaotic field distributions all components of
the electromagnetic field were found to be uncorrelated and Gaussian
distributed.
