左手介质组成的完美透镜的两种不同的理论分析

Analyses of Two Theories about Perfect Lens Made from Left-handed Materials

在分析了两种不同的左手介质组成的基础上,根据电磁理论,从传统透镜的理论缺陷入手,利用传统光学性质和传输线理论两种不同的方法来分析,利用倏逝波在左手介质中被放大的性质,解析地研究由左手介质组成的完美透镜以及完美透镜成像的原理.

Basing on analyzing two different kinds of left-handed materials, with the electromagnetic theory, and the drawback of traditional lens＇theory, using the two methods-- traditional optical nature and the theory of transmission-line, using growing evanescent waves in the left-handed materials, the paper makes study on perfect lens made from left-handed materials and the principle of forming image of perfect lens.
