Figure 2
Schematic representation of the field [\Omega] of numerical integration. The figure shows only two lenses for simplicity. In simulations all 30 lenses are included in the parallelepiped [\Omega]. The wave before the system of lenses has the form A(0,y,z) = [({1}/{2\pi\sigma^2})\exp(-y^{2}+z^{2}/{2\sigma^2})]. Then the wave propagates in a heterogeneous medium, and lenses create the heterogeneity of the medium. The mesh is schematically pictured with parallel lines in crimson. The real mesh is more dense and contains 100000 parallel lines.
