Abstract

Electromagnetic metamaterials are designed to have properties not found in natural materials. For example, it was shown that one can achieve artificial magnetism at optical frequencies, negative refraction, enhanced chirality and optical activity [4]. Importantly, metamaterials allow separate engineering of electric, magnetic, as well as bianisotropic properties, including chirality. Chiral composite structures demonstrate giant optical activity near the resonance of meta-atoms [2].
