中文摘要：

基于传输线方法，制备了含左手材料和右手材料的一维光子晶体.通过仿真软件ADS的模拟和矢量网络分析仪的测量，研究了光子晶体的传输特性.实验结果表明：由左手材料和右手材料构成的一维光子晶体具有零平均折射率（zero-n）带隙，这一带隙处于左手通带和右手通带之间.zero-n带隙分别由零平均介电常量和零平均磁导率决定，进而对晶格尺度不敏感.

英文摘要：

One-dimensional photonic crystals composed of left-handed and right-handed materials are fabricated by using transmission lines （TLs） approach.The transmission properties of the photonic crystals are simulated by the advanced design system （ADS） of Agilent and measured by the vector network analyser.The results indicate that the photonic crystals possess zero-n-gap which exists between the left-handed passband and right-handed passband.The special gap edges are determined by zero average permittivity ε-=0and zero average permeability μ-=0respectively,so it is insensitive to the scale length.
