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-)带隙,这一带隙处于左手通带和右手通带之间.zero-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.
Based on the transmission line method, a one-dimensional photonic crystal with left-handed material and right-handed material was prepared. The transmission characteristics of photonic crystal were studied by simulation of ADS and vector network analyzer. The experimental results show that the left- The one-dimensional photonic crystal has a zero-mean bandgap, which lies between the left-hand and right-hand passbands. The zero- bandgap is defined by the zero mean dielectric constant and the zero-mean-permeability The rate decision is further insensitive to the lattice scale.
