Acoustic wave interaction with bodies covered by a thin compressible layer

Abstract

The problem of acoustic wave interaction with rigid bodies on whose surface there is a thin compressible layer is formulated. The motion of the material is assumed to be quasi-two-dimensional in the layer, which results in a problem with special boundary condition, which generalizes the problem of acoustic wave diffraction by a rigid body and a cavity. The problem of plane acoustic wave diffraction by a sphere covered with a thin compressible layer is solved.
