    "abstract": "A domain integral method employing a specific Green\u0027s function (i.e.,\nincorporating some features of the global problem of wave propagation in an\ninhomogeneous medium) is developed for solving direct and inverse scattering\nproblems relative to slab-like macroscopically inhomogeneous porous obstacles.\nIt is shown how to numerically solve such problems, involving both\nspatially-varying density and compressibility, by means of an iterative scheme\ninitialized with a Born approximation. A numerical solution is obtained for a\ncanonical problem involving a two-layer slab.",
