The Spectral Ewald method for singly periodic domains
Davoud Saffar Shamshirgar, Anna-Karin Tornberg
We present a fast and spectrally accurate method for efficient computation of the three dimensional Coulomb potential with periodicity in one direction. The algorithm is FFT-based…

Fast Ewald summation for free-space Stokes potentials
Ludvig af Klinteberg, Davoud Saffar Shamshirgar, Anna-Karin Tornberg
We present a spectrally accurate method for the rapid evaluation of free-space Stokes potentials, i.e. sums involving a large number of free space Green's functions. We consider su…
