低频“超材料”结构不同周期性排列方式特性分析

Characteristic analysis of different periodic arrangement ways of low-frequency metamaterial structure

  • 摘要: 以低频“超材料”的矩形双层螺旋体单元胞为建模基础,在HFSS软件中仿真研究了该模型的周期性平铺排列结构、周期性平行排列结构、周期性十字交叉排列结构的S参数,并采用S参数提取法提取了等效电磁参数,分析了3种排列方式在低频频域内呈现出的不同“超材料”特性。仿真结果表明,周期性平铺排列结构可将入射波完全反射回去,周期性平行排列结构为低频磁负“超材料”,周期性十字交叉排列结构为低频左手材料。

     

    Abstract: S parameters of three periodic arrangement ways of low-frequency metamaterials structure were simulated by HFSS software based on square dual-layer planar spiral structure model, including periodic tiling arrangement structure, periodic parallel arrangement structure and periodic cross arrangement structure. Effective electromagnetic parameters were extracted from the S parameters to analyze metamaterial characteristic of the three arrangement ways in low-frequency range. The simulation results show that the incident wave can be completely reflected back by the periodic tiling arrangement structure, the periodic parallel arrangement structure is a kind of low-frequency magnetic negative metamaterial and the periodic cross arrangement structure is a kind of low-frequency left-handed material.
