摘　　要：采用周期矩量法对介质覆盖的高阻表面进行数值分析,绘出其能带结构图,并测试高阻表面加载不同介质时的表面波带隙,对理论分析的结果进行验证,为介质覆盖的高阻表面的设计提供参考.In this paper a kind of high impedance substrate surface covered with different dielectric layer is analyzed by periodic moment method, their band-gap diagrams are described. Meanwhile, the propagating property of surface wave of the high impedance ground plane with different dielectric covering is tested, the results of theoretic analysis are validated. Our results can be helpful for the design of high impedance ground plane with a dielectric cover layer.
