We demonstrate the effectiveness of our algorithm on sphere problems involving large numbers of unknowns, such as a sphere of radius 120 lambda discretized with 53 million unknowns.EnglishElectromagnetic wave scatteringHierarchical parallelizationMultilevel fast multipole algorithmLarge-scale scattering problemsMLFMASphere problemsConference Paper10.1109/APS.2008.4619601
