Abstract :
We develop a Multilevel Fast Multipole Algorithm (MLFMA) for higher order Moment Methods that, unlike extant higher order MLFMA implementations, maintains optimal scaling independent of the patch size.We employ the new scheme to both accelerate preconditioner computation and apply it to the Generalized Method of Moments to analyze scattering from large PEC objects.
