Double negative materials with simultaneously negative dielectric constant and magnetic permeability have some u nique physieal properties, and cause global attention. Metamaterials have huge potential applications in communicalions, medicine, military, biological imaging etc. , because of the special electromagnetic wave propagation properties in metamaterials, which are different from those in conventional media. In recent years, research activities in metamaterials, especially in optical negative index materials(NIMs) have obtained remarkable progress. In this brief review, new structures, loss redue tion and tenability of linear optical metamaterials; new rules of nonlinear optical metamaterials; optimization design and its preparation technology for optical metamaterials; and optical metamaterials' potential applications are reviewed and the possi ble developing direetions of these branches are predicted.
