Exterior moment method analysis of conducting scatterers by using the interior Green's function and the method of least square

A method previously proposed by the authors in 1988 for obtaining the mutual admittance matrix in the moment method analysis by using the interior Green's function is improved by introducing the method of least square (MLS). A numerical example of a two-dimensional problem shows that accurate results can be obtained by introducing the MLS even when arbitrary sources are assumed for numerical experiments in the interior region.<
