Abstract

This paper presents the Multiscale CBD method for accelerated direct solution of scattering and radiation problems with the Method of Moments. The method has all the advantages of a direct solution and it is essentially parameter-free (there is only a parameter tau controlling accuracy against efficiency). It has an improved efficiency and storage requirements with respect to the ordinary CBD. Two significant computations have been presented, an open pipe and the NASA almond.
