μ -diff: An open-source Matlab toolbox for computing multiple scattering problems by disks

Abstract The aim of this paper is to describe a Matlab toolbox, called μ -diff, for modeling and numerically solving two-dimensional complex multiple scattering by a large collection of circular cylinders. The approximation methods in μ -diff are based on the Fourier series expansions of the four basic integral operators arising in scattering theory. Based on these expressions, an efficient spectrally accurate finite-dimensional solution of multiple scattering problems can be simply obtained for compl... Title of program: μ-diff Catalogue Id: AEWH_v1_0 Nature of problem Modeling and simulation of two-dimensional multiple wave scattering by large clusters of circular cylinders for any frequency. The program is well-designed to manage highly accurate solutions for deterministic or random media, with various boundary conditions and physics properties of the scatterers. Pre- and post-processing facilities are designed specifically for these problems.
