Integral-equation formulations of scattering problems are solved iteratively by employing a parallel implementation of the multilevel fast multipole algorithm. Due to ill-conditioned nature of the problems, advanced preconditioning techniques are used to obtain rapid convergence in the iterative solutions. By constructing a sophisticated simulation environment, we accurately and efficiently investigate large and complicated MM structures. © 2007 IEEE.EnglishAircraftElectromagnetismIntegral equationsMagnetismMaterials scienceMethod of momentsParallel algorithmsSolutionsComputational electromagnetics (CEM)Integral-equationIterative solutionsMetamaterial (MM)Multilayer (ML)Multilevel fast multipole algorithm (MLFMA)Parallel implementationsPreconditioning techniquesRapid convergenceScattering problem (SP)Simulation environmentsSplit ring resonator (SRR)Transmission problemsUnit cellsIterative methodsConference Paper10.1109/CEM.2007.4387656
