MINIMIZING THE SCATTERING OF SOUND BY A SPHEROID NEAR AN IDEAL SURFACE BY SELECTING PARAMETERS OF THE OUTER LAYER
The problem of searching for the inhomogeneity parameters of an ellipsoid outer layer is considered. The purpose of the solution is to minimize the reflection of sound in a given range of angles. The choice of parameters is based on the solution of the problem of diffraction of a plane sound wave on an elastic ellipsoid with a layer-inhomogeneous coating. The ellipsoid is immersed in a half-space filled with an ideal fluid. The boundary of a halfspace is an ideally rigid or soft surface. At the decision the introduction of a mirror obstacle i s used. The choi ce of the parameters of the l ayer i s shown i n the speci al case.
