| 摘 要： | 电磁带隙结构是光子晶体中的一种,它可以广泛地应用于微波、毫米波波段.研究了一种具有蝶形单元的电磁带隙结构,通过理论分析获得它的ABCD矩阵,将ABCD矩阵转换为散射矩阵,进而得到该结构的频率特性.在这种电磁带隙结构中引入缺陷,采用同样的分析方法获得它的频率特性.通过仿真计算可以看出,具有蝶形单元的电磁带隙结构大约有2.8 GHz带宽的阻带,相对带宽为52%;而具有缺陷的电磁带隙结构在阻带中形成一个具有一定带宽的通带,且通带的频率很容易调整.

| Abstract: | Electromagnetic bandgap(EBG)structure,which can be widely used in microwave and millimeter-wave fields,is a kind of photonic crystal.An EBG structure with bow-tie unit was researched in this paper.Based on theory analysis,the ABCD matrix is gotten and transferred into scatter matrix,which means its frequency characteristics are obtained.A defect is introduced into the EBG structure.Furthermore,the same method is adopted to compute its frequency characteristics.The simulation results show that the EBG struct... |
