✦ Synopsis

In

this paper, we consider the inverse scattering problem of a plane acoustic wave by a multilayered obstacle which is important in various areas of imaging and nondestructive testing. When the core is penetrable (with transmission boundary conditions), we obtain that the core is determined uniquely by the corresponding far field pattern.

The inverse problem we consider is to determine the shape of an obstacle from a knowledge of the far field pattern for the scattering of incident time-harmonlc acoustic (or electromagnetic) plane waves. It occurs in a variety of applications and is difficult to solve since it is nonlinear and improp
