Recently, a new technique referred to as the on-surface radiation boundary condition (OSRC) approach was introduced and applied to a class of perfectly conducting cylinders for computing their scattering. Here the OSRC method is applied to a variety of two-dimensional imperfectly conducting geometries. Specifically, analytical solutions and numerical data are presented for the scattering by elliptical and rectangular cylinders and resistive strips. The primary interest in this investigation is to offer a comparative examination of the accuracy of the OSRC method in predicting the scattering by the aforementioned general class of structures.
