## Abstract We apply the Ewald acceleration technique to the efficient evaluation of periodic Green's functions (GFs) for 3βD skewed lattices like those arising in electromagnetic/photonic bandβgap (EBG/PBG) structures and metamaterials (MTMs). We develop the expression for the optimal value of an
The Ewald method is applied to accelerate the evaluation of the Green's function (GF) of an infinite equispaced linear array of point sources with linear phasing. Only a few terms are needed to evaluate Ewald sums, which are cast in terms of error functions and exponential integrals, to high accurac
