摘要
根据微波传输线理论, 结合集总元件构造的复合左/右手传输线, 分别实现了负介电常数材料和负磁导率材料, 并进一步制作了由这两种单负材料交替组成的一维光子晶体。仿真与测量结果显示, 该光子晶体结构可产生零有效相位带隙。若结构参数能同时满足阻抗匹配条件和相位匹配条件, 零有效相位带隙将消失。若两个匹配条件无法同时被满足, 零有效相位带隙将始终存在, 带隙中心处在阻抗匹配频率。此外, 在阻抗匹配频率处, 若结构参数偏离相位匹配条件越大, 零有效相位带隙将越宽且越深, 通过此规律可实现对带隙的调制。
Abstract
According to the theory of microwave transmission line, the permittivitynegative and permeabilitynegative materials were realized and then onedimensional photonic crystals constituted by alternating singlenegative materials were fabricated by using composite right/left handed transmission lines with lumped elements. Simulation and measurement results show that such photonic crystals may produce zeroeffectivephase (zeroφeff) gap. When the structure parameters satisfy both impedancematch and phasematch conditions simultaneously, the zeroφeff gap closes. When the two matching conditions cannot be satisfied at the same time, the zeroφeff gap always exists and its center locates at the central frequency. Furthermore, at the impedancematch frequency, the greater the phasematch condition deviates from being satisfied, the bigger and wider the zeroφeff gap will be. Such properties can be used to control to the zeroφeff gap.
