突破衍射极限的超级透镜技术及其应用研究

Based on metamaterial structure, superlenses can bring the evanescent wave from the object plane to the image plane, which corresponds to an optical resolution beyond a half wavelength. The principle and researching process of several typical superlenses, such as near-field superlens, far-field superlens and hyperlens are illustrated in detail in this paper. The applications prospect of superlens technology such as bio-image in time, optical data storage and photolithography are analyzed and summarized.
