Abstract
The problem of wave propagation in a nonuniform elastic layer located between two compressible liquids with different physical properties is stated and solved by series expansion in the small coordinate. It is shown that different types of inhomogeneities in the layer can cause strong concentration of the wave fields in either the central portion or near the boundaries of the layer.
