Quantum chaos in the 3D electrodynamic systems of millimeter wave range

Two quasioptic electrodynamic 3D systems were chosen for the experimental investigation of quantum chaos (QC) effects. The propagation of an electromagnetic wave in the first system takes place under the conditions of local instability similar to the particle instability in the scattering Sinaj's billiard (S-system). The second system is an analogy to the focusing Bunimovich billiard (B-system).
