Abstract :
A technique referred to as the on-surface radiation boundary condition (OSR) approach 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 restrictive strips. These are then compared with calculations using the traditional physical optics (PO) approximation and moment method (MM). Emphasis is on the accuracy afforded by using OSRC as opposed to the MM or PO formulations
