从电磁场理论推导了光波在负折射率介质薄层中的传输矩阵 ,对由正、负折射率介质构成的全介质布喇格反射镜的反射带宽和角度特性进行了分析和讨论 ,与普通的均由正折射率介质构成的布喇格反射镜的相应特性做了对比 ,并根据薄膜理论对研究结果作了解释

Transfer matrix of a negative refractive index medium (NIM) layer is derived from electromagnetic boundary conditions. Based on the transfer matrix method, the anomalous optical properties of an all-dielectric Bragg mirror containing NIM layers are simulated and compared to the corresponding characters of the Bragg mirror of the same structure with positive refractive index medium (PIM) layers. The results show that the Bragg mirror containing NIM layers have broader reflection band and better angular property than that of ordinary Bragg mirror.
