Abstract

As a typical uniaxial media, stratified metal-dielectric metamaterials (SMDMs) are addressed in my talk. SMDMs have diverse features: (I) Coexistence of metallic and transparent dielectric properties in SMDMs. (II) Nearly zero refractive index just above the effective plasma frequency of metallic components. This feature has enabled to design the ultracompact wave plates. (III) In case of the small ratio of metal, the transmission windows emerge which are often connected to the optical magnetism. In some particular cases, negative refractive index is also found. (IV) When the metal part is dominant, SMDMs can have the very large refractive index.
