It is known that the Jost-function formulation of quantum scattering theorycan be applied to classical problems concerned with the scattering of a planescalar wave by a medium with a spherically symmetric inhomogeneity of finiteextent. This technique is applied to solve the radial differential equation forthe scattering from a constant spherical inhomogeneity and a piecewise constantby two-layer spherical inhomogeneity. This could represent a sphericalscatterer with a piecewise increasing or decreasing refractive index, forexample. When the problem cannot be solved analytically in closed form, theJost integral formula can be used to convert it into an integral equation withthe corresponding boundary conditions.
