A method toward improved convergence of moment-method solutions

A technique for improving the convergence of moment-method solutions through the use of a priori knowledge is presented. The idea is that known good approximations such as physical-optics current may be subtracted from the unknown total current with the result that the residual difference current, which is now the quantity to be determined, will converge more rapidly. Use of this method as applied to plane-wave scattering from conducting strips is given as an example.
