The computation of the space-domain Green's function is accelerated using the Ewald transformation. The method is validated on several periodic structures ranging from planar frequency-selective surfaces to three-dimensional photonic crystals and metamaterials. For these structures, our technique shows a clear advantage in terms of computational speed when compared with available commercial softwares.Frequency-selective surfaces (FSSs)Green's functions (GFs)integral equations (IEs)metamaterialsperiodicstructuresphotonic bandgap (PBG) materials.text::journal::journal article::research article
