Efficient linear system solution in moment methods using wavelet expansions
Federico Malucelli, Luciano Tarricone · IEEE Transactions on Antennas and Propagation · 2000
An efficient strategy is proposed to solve linear systems encountered when method of moments (MoM) and wavelet expansions are used. It exploits a high-performance matrix bandwidth reduction algorithm so that it can be taken advantage of direct banded solvers, which have a more favorable computational complexity with respect to the typically used iterative sparse methods. Speedups of up to seven have been experienced with respect to standard iterative sparse solvers.
