[en] In recent years, the generalized multipole technique (GMT) and other fictitious source methods have been widely used to solve electromagnetic scattering problems. Nevertheless, these methods have been shown to be very sensitive to the source locations, and often produce ill-conditioned matrix systems. The current approach suggests a kind of synthesized directive expansion to reduce the dependence on the source locations, the condition number of the impedance matrix, and the number of unknowns.
