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.File in questo prodotto:
