Problems are formulated with the electric and magnetic current combined-field integral equation (JMCFIE) and solved iteratively with MLFMA on distributed-memory architectures. Numerical examples involving canonical and complicated objects, such as optical metamaterials, are presented to demonstrate the accuracy and efficiency of the implementation. © 2012 IEEE.EnglishCombined field integral equationsComposite objectsDistributed memoryElectromagneticsLarge-scale problemMagnetic currentsMetallic partMultilevel fast multipole algorithmsNumerical exampleParallel implementationsAntennasOptical materialsIterative methodsConference Paper10.1109/APS.2012.6347936
