Anisotropic 3-D right/left handed metamaterial structures composed of stacked layers using dielectric resonators and mesh plates

New configuration of anisotropic 3-D composite right/left handed metamaterial structures is proposed and designed. It is composed of stacked layers using conducting mesh plates and dielectric layers including 2-D array of dielectric resonators. Balanced composite right/left handed transmission structures are designed not only for the propagation direction parallel to the layers, but also for the normal direction. The structure is essentially anisotropic and has polarization dependence for the wave propagation. Still, for the wave propagation with the polarization parallel to the mesh plates, it can provide relatively small anisotropic propagation characteristics in some frequency region by appropriately designing the configuration parameters. The negative-refractive-index flat lens is demonstrated for the validation.
