摘　　要：根据菲涅尔公式,从理论上证明了只有在左右手系两种介质中光波才能发生全折射现象,给出了产生全折射时介质折射率应满足的条件n1=-n2,μ1=-μ2.对n2=-1的负折射率平板的成像进行了分析讨论,此负折射率平板具有透镜的作用.Based on Universal Fresnel formulae, the properties of reflection and refraction of optical waves are analyzed. The results show that the total refraction only occurs between Left-handed and Right-handed materials. Total refraction condition n1 =- n2μ1 =-μ2 in two medium are given. The imaging of the slab of negative index matrial with n2 =- 1 is discussed.
