| 摘 要： | 介绍了负折射率现象及其优良的光学性能,并从麦克斯韦方程出发推导了正负折射率介质薄层的转移矩阵,经模拟计算发现:正负折射率交替的一维光子晶体有很宽的光子禁带和狭窄的透带,而且无论是TE波还是TM波在中心波长光学特性几乎都不受角度的影响,可用作宽带全方位反射镜,可望在在光路集成、光通信领域得到广泛地应用。

| Abstract: | The phenomena of negative refractive index and excellent optical performance were introduced.The transfer matrixes of positive and negative refractive index medium(PRM and NRM) layer were also derived from Maxswell equations.The numerical simulation revealled that 1-D photonic crystal with PIM-NIM alternant multilayer had very broad forbidden band and narrow transmitted band.Furthermore,the optical properties in central wavelength of either TE wave or TM wave was hardly affected by the angle,which could be used as broad-band and omnidirectional reflecting glass.It's promising that it can be widely applied in integrate optics and optical communication. |
