Abstract:
A wideband fast integral solver employing a fast Fourier transform accelerated multilevel Green's function interpolation method (MLIPFFT) combined with the multilevel fast multipole method (MLFMM) is presented. On fine levels of the employed oct-tree structure, the low frequency stable MLIPFFT is utilized. At a certain wavelength dependent threshold for the box size, the interpolation point based representation of the MLIPFFT is converted into its k-space representation suitable for an MLFMM.
