N2 - A novel iterative physical optics (IPO) algorithm for the analysis of scattering from large complex semi-transparent geometries is proposed. Two main modifications of the conventional IPO scheme are introduced to model penetrable scatterers: The geometry is divided into non-overlapping connected homogeneous domains and the fields transmitted between the domains are evaluated, in addition to the conventional reflected field calculations. The algorithm comprises two types of nested iterations: reflection/transmission ('bounce') iterations and iterative shadowing ones. The scheme is applied separately to the bounding surfaces of each domain. The interaction between the domains, through transmission, is accounted for at the conclusion of each bounce iteration. The algorithm is demonstrated to provide a good approximation of an analytical reference solution.
