【 摘 要 】

Iterative algorithms are constructed for 2D modeling of diffraction of sound and linearly polarized S-wave on an inclusion having a hierarchical elastic structure in a J-th layer of an N-layer elastic medium. Under analysis are the cases when the inclusion of each rank and the enclosing medium have different densities and the same elastic parameters and when they have the same densities and different elastic parameters. The space-frequency representation of the wave field distribution uses the methods of the integral and integral-differential equations.
