Scattering of a point generated field by a multilayered spheroid

The point source excitation acoustic scattering problem by a multilayer iso tropic and homogeneous spheroidal body is presented. The multilayer spheroi dal body is reached by an acoustic wave emanated by an external point sourc e. The core spheroidal region is inpenetrable and rigid. The exterior inter face and the interfaces separating the interior layers are penetrable. The scattered field is determined given the geometrical and physical characteri stics of the spheroidal body, the location of the point source and the form of the incident field. The approach is not limited in a certain region of frequencies.
