The effects introduced in the dispersion of surface
waves supported by a metasurface consisting of a negligible thickness
perfectly conducting screen perforated with a finite array
of slots are studied by means of a very efficient implementation
of Galerkin’s version of the Method of Moments with a DeltaGap
excitation. A family of higher frequency modes each of
which is periodically repeated in the momentum spectrum with
decreasing amplitude is found in contrast to the single mode
dispersion obtained for an infinite array.
