提出了一种双面环各向同性结构单元模型, 理论与实验研究了其微波电磁谐振行为. 结果表明: 在电磁波平行入射和垂直入射条件下, 该结构可在同一频段实现磁谐振, 且在谐振频段磁导率为负; 当电磁波以不同角度斜入射时, 其产生负磁导率频段也保持不变, 即该结构的电磁特性不依赖于入射角度, 双面环结构具有各向同性的特点. 将双面环结构与金属线结构组合, 该组合结构具有负折射率. 另外,双面环结构还具有小型化的优点, 在不增加结构单元几何尺寸的情况下, 通过在结构单元中引入金属化过孔的方法, 增加结构单元的电长度, 可使谐振频率大幅度地向低频方向移动, 使其在低频工作时 仍保持小型化的优点. 在双面环结构中引入金属化过孔技术可使谐振单元的几何尺寸减小50%, 在微波器件、滤波器、天线等领域有广阔的应用前景.
