Abstract

This paper presents the multiple sweep method of moments (MSMM) analysis of the radiation and scattering from electrically large, smooth, perfectly conducting bodies. The MSMM is an O(N²) recursive method for solving the large matrix equations, which arise in the method of moments (MM) analysis of electrically large bodies. In the MSMM, the body is split into P sections and the currents on these sections are found in a recursive fashion. The first MSMM recursion or sweep includes the dominant scattering mechanisms and each subsequent recursion or sweep includes higher order mechanisms. Thus, as the electrical size of the body increases, fewer and fewer sweeps are required to accurately compute the current on the body
