Abstract

A new efficient approach for converting multipole series coefficients to plane wave samples and back is presented in detail. The presented algorithm utilizes the fast Fourier transform in order to speed up the process. It can be used to develop an efficient implementation of a broadband multilevel fast multipole algorithm (MLFMA). The numerical tests demonstrate that the presented process also allows full numerical error control, which is an important factor in a practical implementation.
