Remote determination of mechanical parameters of thin tunnel elastic inclusions

The inverse problem on the remote determination of the physical-mechanical parameters of thin plane tunnel elastic inclusions with variable thickness is considered. It is assumed that the mechanical properties of non-homogeneity and matrix differ insignificantly in comparison with the relative thickness of non-homogeneity. Elastic longitudinal waves are used as sounding waves, and the unknown parameters are defined according to the scattering amplitudes of these waves in the Fraunhofer zone.
