Abstract :
A fast direct (non iterative) solution method for the method of moments (MoM) in electromagnetics is proposed. The method uses the well known matrix decomposition method (MDA) and singular value decomposition (SVD) to achieve block-wise compression of the MoM impedance matrix, followed by a block-wise LU factorization that preserves the initial compression. A number of examples are presented involving problems ranging from ten to seventy thousand unknowns.
