Stochastic Properties of the Billiard-Type Three-Dimensional Electromagnetic Microwave Systems
RÉSUMÉ
Stochastic spectra of the 3D electromagnetic quasioptical systems which are similar to the Sinai scattering billiards (S-system) and Bunimovich billiards (B-system) have been experimentally investigated for the millimeter wave band over the interval of 34 to 38 GHz. The effects peculiar to the systems with quantum chaos such as the frequency repulsion effect and closeness of the inter-frequency interval distribution to the Wigner distribution are found to be observed in these spectra. However, they differ considerably from similar systems in spectral rigidity and correlation properties of those intervals. It is also found that a mechanism of the wave propagation instability in the Bunimovich billiard caused by the defocusing of waves gives rise to the spectrum stochatization in the Sinai scattering billiards. In addition, the effectiveness of spectrum stochatization is observed to be influenced by the magnitude of the Kolmogorov-Sinai system entropy.
