Abstract :
The fast multipole method (FMM) can be applied to the computation of radiation and scattering from infinite periodic structures by applying the Ewald summation technique to the FMM translation operator. When the, FMM group is taken to be a unit cell in the structure, this results in a large saving in the setup times compared to a straightforward FFT approach.<>
