简析负折射率及其效应

Analysis of Negative Index of Refraction and Effect

介绍了负折射率材料的发现及研究历史,简单分析由负折射产生的负群速度、逆多普勒频移、反常切伦柯夫辐射、完美透镜等各种效应,进一步讨论负折射材料的应用展望。

The paper introducs the history and research of negative refrac, tive materials and simply analysis of negative index of refraction gives rise to the strange properties such as negative group velocity, negative refraction, perfect lens, inverse doppler effect and abnormal Cerenkov radiation. The paper also introduces sapplication of negative refractive material.
