Strong lateral displacement in polarization anisotropic extraordinary transmission metamaterial

摘要: In this paper, a deep numerical as well experimental study of the anisotropy response extraordinary transmission metamaterials constructed by stacking subwavelength hole arrays is presented. Two-dimensional (2D) dispersion diagrams for S- and P-polarization were obtained from simulation. From them, it was found that negative refraction can be latter case small angles incidence. Additionally, double periodic dielectric loaded are optimal to enlarge aperture leads refraction. Several experiments then presented in V-band millimetre-wave range show excellent agreement with calculations. Moreover, richness anisotropic characteristic exhibited stacked array structure allows designing structures complex electromagnetic other than solely Thus, results here could taken novel route achieve exotic behaviour, such at frequency ranges, like terahertz or visible.
