Abstract :
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
