Abstract

Diffraction of the field of a point source by a body of revolution is considered for the case where the body is positioned in a plane layer bounded by a perfectly soft boundary on one side and by a fluid half-space on the other side. Characteristics of the medium inside the layer are assumed to depend in a continuous manner on the vertical coordinate. The proposed method is tested by comparing the results of wave field calculations for the case of a constant sound velocity profile within the plane layer and also by comparing the given method with the surface integral equation method. It is shown that the sound field is considerably affected by inhomogeneity of the medium within the layer.
