太赫兹波段多间隙超材料共振模式转换

Resonance mode transformation of multi-gap metamaterial in the Terahertz regime

针对超材料模式转换研究较为匮乏的问题,采用多间隙超材料结构,对中心间隙的不同连接方式进行研究,发现在水平极化入射的情况下,水平连接会产生一种新的电感电容(LC)谐振,从而引起模式转换效应,而垂直连接不会引起任何变化。该研究可为太赫兹波的控制、太赫兹波段调制器和传感器的设计提供理论支持。

For the short of research in mode transformation of metamaterials,different types of connections are studied in the center gaps with multi-gap metamaterial structure.In the horizontal polarization incident,it is found that the horizontal connection will cause a new type of inductance capacitor(LC)resonance,leading to the mode transformation effect,while the vertical connection will not cause any change.The study may provide theoretical support in the control of Terahertz waves and the development of modulators and sensors in the Terahertz band.
