Determination of the inhomogeneity laws for an elastic layer with preset sound-reflecting properties

摘要

The problem of determining the inhomogeneity laws for a plane elastic layer characterized by minimum reflection of a plane sound wave with a preset angle of incidence is considered. Based on an analytic solution to the direct problem, a functional expressing the reflection intensity is constructed and an algorithm for its minimization is proposed. Analytic expressions describing the mechanical parameters of the inhomogeneous layer are derived.
