✦ Synopsis
In this article we present a novel approach to incorporating wavelet expansions in method-of-moments (MOM) solutions for scatteringproblems described by a magnetic field integral equation (MFIE) formulation. In this approach, we utilize the fact that when the basis functions used are wavelet-type functions, only a few terms in a series expansion would be needed to represent the unknown quantity. An iterative procedure is suggested to determine these dominant expansion functions. The new approach combined with the iterative procedure yields a new algorithm that has many adcantages over the presently used methods for incorporating wavelets. Numerical results that illustrate the approach are presented.
