Abstract

It is proposed that a convenient choice of basis functions for applying the moment method to the analysis of scattering and/or mutual coupling between metallic bodies impinged upon by an electromagnetic field is that of the characteristic modes of a single scatterer. Due to the resonant behaviour of such modes, only a small number of them are required for an accurate representation of the current distribution even in the presence of mutual coupling. Results for the case of two-dimensional strips are reported and compared with those obtained with the conventional, direct application of the moment method.
