一种基于石墨烯栅带结构的电控太赫兹偏振片及使用方法
Hits:

Affilication of Author(s):物理学院

Patent Coverage:国内

School Sign:第一单位

Note:本发明公开了一种基于石墨烯的电控太赫兹偏振片,包括至少两层石墨烯层,每层石墨烯呈栅带结构,每两层相邻的石墨烯层间设有介质层,介质层将两层石墨烯层分隔开;偶数层的石墨烯层共同连接在一个电极上,奇数层的石墨烯层共同连接在另一个电极上,在两个电极上加载电压可实现电压调控。本发明利用多层膜结构制备的偏振片,可以通过栅带的结构参数,如栅带的宽度、空间周期等,以及石墨烯的层数而调控响应频段、偏振度等性能参数;通过电压调控,可以主动调控透过太赫兹波的偏振度,本发明除了偏振的功能以外,还能够实现对不同偏振方向太赫兹波选择性调制的功能。
