Abstract
A novel formulation for improving the numerical stability of the null-field method for highly elongated and flattened layered scatterers is presented. The key step in this approach is to approximate the surface current densit ies by the lowest-order multipoles located in the complex plane. The accura cy of the proposed method is investigated from a numerical point of view. ( C) 2001 Elsevier Science B.V. All rights reserved.
