The hybridization of fast multipole method with asymptotic waveform evaluation for the fast monostatic RCS computation

The fast multipole method hybridized with the asymptotic waveform evaluation is presented in this paper to efficiently calculate the scattering from electrically large objects. A novel interpolation method for the hybridization is proposed, which provides a more accurate result for the scattering pattern calculation than the original extrapolation method. The accuracy and efficiency of this proposed hybrid method are examined through numerical examples.
