In this work, we present a simple numerical technique, viz. the generalized sparse matrix reduction (GSMR) technique, to generate a sparse matrix while applying the well‐known method of moments (MoM) to electromagnetic scattering problems. The crucial step in the numerical procedure to generate the sparse matrix involves choosing a set of current distributions defined over the entire structure. Since the present technique generates a sparse matrix, this amounts to considerable savings in terms of computer storage/CPU requirements. Finally, we present some representative numerical examples to demonstrate the validity of this new method. © 1998 John Wiley & Sons, Inc. Microwave Opt Technol Lett 19: 271–274, 1998.
