Abstract
An iterative physical optics (IPO) algorithm for the analysis of scattering by penetrable acoustically large objects, composed of penetrable and opaque surfaces, is proposed. The scatterer surfaces are assumed in general to be non-convex and multiply connected, such that self-shadowing effects should be accounted for. This is done by extending the shadow radiation IPO (SR-IPO) scheme, developed for the case of impenetrable surface scatterers. For the penetrable surfaces case, the IPO scattering problem formulation is modified in order to make it compatible with the SR-IPO process. The key features of the formulation are discussed and a rudimentary validation of the formulation is presented for an acoustically representative example.
