An improved moment method for the scattering by large conducting cylinders

In this paper we show that the use of the method of moments [l] together with the exact solution for the scattering by a single scatterer can be combined to produce an efficient solution for the scattering by multiple bodies without any restriction. The total scattered field is divided into two components, namely a non-interaction term and a term due to all interactions between the scatterers. The non-interaction term is expressed exactly, whereas the interaction field is evaluated using the ordinary method of moments. The method is applied here to two circular conducting cylinders although it can be employed for any arbitrary number of cylinders.
