Computation of the One-Dimensional Free-Space Periodic Green's Function for Leaky Waves using the Ewald Method
Abstract
This paper examines an extension of the Ewald method for evaluating the periodic free-space Green's function due to an array of point sources, when the wavenumber of the phased sources is allowed to be complex. This makes the Ewald method useful for treating leaky modes on periodic structures. © 2012 IEEE.
