Planar wallpaper group metamaterial for novel terahertz applications

摘要

We present novel metamaterial structures based upon various planar wallpapergroups, in both hexagonal and square unit cells. An investigation ofmetamaterials consisting of one, two, and three unique sub-lattices withresonant frequencies in the terahertz (THz) was performed. We describe thetheory, and perform simulations and experiments to characterize these multipleelement metamaterials. A method for using these new structures as a means forbio / chemical hazard detection, as well as electromagnetic signature controlis proposed.
