完美透镜可以突破衍射极限实现亚波长成像,具有重大的应用价值.该概念的物理效果已经通过微波二维传输线实验得到验证,目前人们关心的是在光波段是否也可以制作出完美透镜.本文简要回顾了完美透镜概念的产生和发展过程,并从理论机制、器件参数和制备能力等角度阐述了它在光波段的发展前景. The perfect lens can overcome the diffraction limit to achieve subwavelength imaging, and has great application value.The physical effect of this concept has been verified by the microwave two-dimensional transmission line experiment, and the current concern is whether or not the perfect lens can also be produced in the light waveband. The generation and development of the perfect lens concept are reviewed, and its development prospect in the light wave band is expounded from the perspective of theoretical mechanism, device parameters and preparation capability.
