传统透镜的成像分辨率受到衍射的限制。现在，通过化学工程设计的超材料提供了建造一个克服这一限制的超级透镜的可能性。本文综述了这类超透镜的物理特性以及这一快速发展领域的理论和实验进展。超透镜在生物医学成像、光学光刻和数据存储等领域有着巨大的应用潜力。
The imaging resolution of conventional lenses is limited by diffraction. Artificially engineered metamaterials now offer the possibility of building a superlens that overcomes this limit. We review the physics of such superlenses and the theoretical and experimental progress in this rapidly developing field. Superlenses have great potential in applications such as biomedical imaging, optical lithography and data storage.
