摘要
提出将磁谐振环-金属线的共面结构与磁谐振环相结合设计双频带左手材料的新方法.设计了一种基于斜三角开口对环结构的新型双频带左手材料,通过对该结构的等效电路和表面电流、电场分布的分析,说明该结构能产生两个双负频段,其中斜三角开口对环-金属线共面结构决定了第1个双负频段,斜三角开口对环结构决定了第2个双负频段.理论分析和仿真、实测结果均验证了该方法的正确性.
A method for realizing dualband left-handed metamaterials is presented. By integrating the magnetic resonator plus wire with the magnetic resonator, a novel left-handed metamaterial based on the Oblique triangular open-loop pairs resonator (OTOR) is presented. By analyzing the distribution of the surface current, electric field and equivalent circuit, the combined structure exhibits double LH passbands. The first LH passband is decided by the OTORq-Wire, while the second LH passband is decided by the OTOR. Simulation and experimental results and analysis verify this design. Furthermore, the idea can help us to design negative-index materials with multibands.
