Paper Abstract

We apply the method of ordered multiple interactions (MOMI) to the magnetic field integral equation for a scattering problem involving an infinitely long cylinder suspended over a numerically-generated randomly rough surface. The cylinder and rough surface are infinite conductors. We consider two- dimensional geometry (invariance in the y-direction) and calculate the scattering of a plane wave which is polarized in the plane of scattering. We examine some convergence characteristics of the MOMI method when applied to this scattering problem. Our results indicate that the MOMI method does not converge for scattering only from isolated cylinders, but converges rapidly for scattering only from randomly rough surfaces. To obtain solutions for the problem with both cylinder and rough surface present, we adopt a hybrid method where the cylinder portion is solved exactly and the rough surface portion is solved by iteration.
