摘要
提出了一种两个反向对称Ⅱ形双频左手材料结构,其中Ⅱ形结构是由在介质基板刻蚀的金属线和金属化过孔组成.通过模拟仿真及电磁参数反演结果表明,当电磁波垂直入射时,该结构在11.1～12.5 GHz和13.3～14.3 GHz这两个频段内具有左手特性,并且实验与仿真结果基本吻合.
A structure of dual-frequency left-handed metamaterial composed of two antisymmetrical H-shaped metal is proposed.The Ⅱ-type metal is composed of via holes and strip wires.By simulation and scattering parameters method,the inversion results indicates that the microstructure exhibits left-handed passband from 11.1 GHz to 12.5 GHz and 13.3 GHZ to 14.3 GHz when it operates under normal incidence directly,and the experimental results coincide with the simulation results.
