By employing a parallel implementation of the multilevel fast multipole algorithm (MLFMA) on relatively inexpensive platforms. Specifically, the solution of a scattering problem with 33,791,232 unknowns, which is even larger than the 20-million unknown problem reported recently. Indeed, this 33-million-unknown problem is the largest integral-equation problem solved in computational electromagnetics.EnglishLarge-scale systemsMLFMATree data structuresElectromagnetic scatteringTransmission line matrix methodsInterpolationComputational electromagneticsElectromagnetic radiationConference Paper10.1109/APS.2007.4396276
