Research output: Contribution to journalConference articlepeer-review


A ray propagation approach used to accelerate the fast multipole method (FMM) of Rokhlin is presented. This technique discretizes the integral equation by using the method of moments and then solves it through an iterative method. However, the bottleneck in the computation is the cost of computing a matrix-vector multiply. Also presented is a non-nested method using the same approach to reduce the cost of a FMM matrix vector multiply to O(N4/3).
