Abstract

本发明公开一种相位可连续调控的太赫兹可重构透射超表面单元，具体结构由一对印制在单层石英基板两侧的金属图案、肖特基变容二极管和直流偏置线组成。其中，金属图案由两个对称分布的“I”型组成，在两个“I”型图案的中间引入一个肖特基变容二极管，利用其电容值的连续变化实现对该透射超表面单元的相位的连续调控。在两个“I”型图案的左右两侧分别引入两段偏置线，用于连接直流稳压电源，通过改变直流稳压源的电压，可以控制肖特基变容二极管的电容值连续变化。本发明具有透射相位可连续调控、透射相移范围大、单元结构简单易于集成等特点，有望应用于太赫兹可重构透射超表面天线的组阵，实现对太赫兹波的灵活调控。
