| 摘 要： | 基于金属短板对和连续金属线(short-slab pair and continuous wires)复合结构,从理论上系统地研究了在THz波段结构参量对左手材料通带位置的影响.数值模拟结果表明,改变金属板宽度或厚度、连续金属线的长度或厚度都会引起左手材料通带位置向较高频段偏移.

| Abstract: | We systematically study the transmission property of metallic short-slab pair and continuous wire structure metamaterial and its dependence on the system geometrical parameters in the infrared frequency regime, using the transfer-matrix method and the commercial code, CST Microwave Studio. It is found that the passband is sensitive to the length and the thickness of the continuous wire. As the length or thickness increases, the passband is slightly extended to a higher frequency. It is also found that the dependence of the passband on the material of dielectric layer. |
