A novel method for the analysis of dispersion in cascaded periodic surfaces

In this work, a novel method for the analysis of the dispersion properties of a cascade of planar periodic surfaces is presented. The proposed approach can be employed for the characterization of the important class of metamaterials consisting of stacks of planar periodic surfaces. The analysis procedure is new and systematic, and it provides a complete description of the dispersion properties of the metamaterial in the whole irreducible Brillouin zone.
