A ray‐propagation fast multipole algorithm

Robert L. Wagner, Weng Cho Chew

Research output: Contribution to journalArticlepeer-review


A new technique is presented for accelerating the fast multipole method, allowing rapid solution of surface integral equations for wave‐scattering problems. A nonnested, ray‐propagation approach is used to compute a matrix‐vector multiply in O(N4/3) operations, where N is the number of unknowns in the discretized integral equation. © 1994 John Wiley & Sons, Inc.
