Plasmonic Metamaterials

Abstract

A plasmonic metamaterial is an artificially designed quasi material that consists of nanometer-scale metal structures. By engineering such a material, we can create unprecedented optical materials whose permeability is changed from unity. In this review paper, recent topics on metamaterials, such as optical metamaterials, plasmonic electromagnetically induced transparency, refractive index control for the realization of high index materials, and novel laser fabrication techniques for three-dimensional metamaterials are introduced.
