多开口环状的三维左手材料的设计

Design of Amultiple-opening Rings Shape of Three-dimensional Left-handed Material

基于谐振型左手材料理论设计了一种三维的左手材料结构。该结构在三维空间中没用介质基板,完全是一个多开口的环状铜板.通过理论分析、软件仿真、测试、提取有效电磁参数,研究结果表明,在114〜369.7MHz范围内,该结构具有谐振特性,在200~500MHz范围实现双负特性,对三维左手材料的广泛应用具有一定的参考意义.

A three-dimensional left-handed material structure was designed based on the resonant theory of left-handed material.The structure had no dielectric substrate in three-dimensional space and was entirely a circular copper plate with multiple-opening.Through theoretical analysis,software simulation,testing and extraction of effective electromagnetic parameters,the research results show that the structure has reso­nance characteristics in the range of 114〜369.7MHz,and achieved double negative properties in the range of 200〜500MHz,which has certain reference significance for the wide application of three-dimensional left-handed materials.
