This paper presents a single-level matrix compression algorithm, termed IE-QR, based on a low-rank approximation to speed up the electric field integral equation (EFIE) formulation. It is shown, with the number of groups chosen to be proportional to N/sup 1/2/, where N is the number of unknowns, the memory and CPU time for the resulting algorithm are both O(N/sup 1.5/). The unique features of the algorithm are: a. The IE-QR algorithm is based on the near-rank-deficiency property for well… CONTINUE READING
