【摘要】 本文在Lee W.Cross研究等离子立方体加载频选单元结构的基础上,进一步分析结构带通特性受频选单元、等离子体密度、入射方向及上中下三层介质之间的影响,设计优化等离子周期结构模型,采用高介电常数介质封装等离子体,使其具有恒定带宽和随入射角变化保持稳定的谐振频率,大入射角时3d B带宽比在1.4:1以下,拓展等离子周期结构研究前景。更多还原

【Abstract】 In this paper, based on the research of Lee W. Cross over load frequency selective structures of the plasma cube, wefurther analyze the impact of the frequency selective unit, the plasma density, the incident direction and in between next three media over the structure of the bandpass characteristics. In our design, when there is a large incidenceangle, 3d B bandwidth will be below1.4 : 1 or less, thus expanding research prospects of periodic structures of plasma.更多还原
