We show that the aggregation and disaggregation stages of the Fast Multipole Method (FMM) can be effectively performed by a type-3 Non-Uniform FFT (NUFFT). The attention is focused on a 2D Electric Field Integral Equation (EFIE). The case of a circular, perfectly conducting cylinder is numerically analyzed and the notable accuracy of the procedure is shown for that test case.

Abstract
We show that the aggregation and disaggregation stages of the Fast Multipole Method (FMM) can be effectively performed by a type-3 Non-Uniform FFT (NUFFT). The attention is focused on a 2D Electric Field Integral Equation (EFIE). The case of a circular, perfectly conducting cylinder is numerically analyzed and the notable accuracy of the procedure is shown for that test case.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
