Abstract:
|
In recent years, several methods have been developed for accelerating the iterative solution
of the electromagnetic integral equations discretized by Method of Moments (MoM). Most
of them are based on the compressibility of parts of the MoM matrix when they correspond
to the interaction between two distant boxes. Among them, a promising one is the Adaptive
Cross Approximation (ACA) [1] which combined with a SVD recompression achieves very
good results, especially for moderately large number of unknowns N. In this paper we
propose a multilevel implementation of the ACA leading to a highly enhanced compression
rate. |
