ITERATIVE IMPLEMENTATION OF APPROXIMATE SOLUTIONS FOR ELECTROMAGNETIC SCATTERING

摘要

This article introduces a recursive formula, in which any approximate method can, iteratively, be incorporated to solve electromagnetic scattering problems. The use of extended Born approximation and quasi-analytical approximation in this formula results in two series (algorithms), whose convergence properties are discussed. Numerical examples are given to demonstrate merits and the range of applicability of the new series.
