Abstract :
This paper compares several methods to accelerate the convergence of the computation of infinite periodic Green´s functions for potentials. Shanks´ algorithm, the summation by parts method and Ewald´s transform are investigated, for an acceleration of the summation both in the space and spectral domains. The algorithms are compared for several array examples.
