摘　　要："左手材料"是与传统材料性质相悖的另外一种材料。根据"左手材料"的特殊性质,采用理论计算与模拟仿真相结合的方法,对影响谐振腔谐振参数的因素进行分析,得出了填充介质的材料属性与谐振腔品质因数、谐振频率的关系。结果显示,"左手材料"的填充,会影响谐振腔的品质因数,相较于介电常数,材料磁导率的作用效果更明显;"左手材料"可以在不改变谐振腔尺寸的基础上提高谐振频率。这相较于传统理论而言有了进一步的进展,为探索和设计新颖的谐振腔提供了理论依据。'LHM'was another kind of material and its natures are inconsistent with traditional materials'.By combining theoretical calculation and simulation,the factors that affect the resonant parameters of the resonator are analyzed.The results describe the relationship between material properties of the filling medium and the resonant parameters of the cavity.Theoretical calculations show that when using the 'left-handed materials'as filling materials in the cavity,the quality factor and resonance frequency can be increased without changing the size of the cavity.This has been proved by HFSS simulation.The conclusion makes the traditional theory have further progress and provides a theoretical basis for the exploration and design of novel resonator.
