    Abstract

    Simulation of waves scattered by a large number of particles is important for several applications-for example, to investigate interac- tions between particles in an ensemble-and hence to design efficient configurations. Substantial computer memory is required for the difrect treatment of an ensemble with hundreds of particles as a single scattering configuration. This memory bottleneck is avoided by using multiple scattering iterative methods, which allow treatment of one particle at a time, but require substantial computing time at each step of the iteration to take into account reflections from the rest of the particles, and require a large number of iterations for convergence. We develop a novel fast, high order, memory efficient algorithm to simulate multiple acoustic scattering induced by an ensemble with hundreds of particles in two space dimensions.
