摘要
论文设计并研究了一种组合双频极化可重构太赫兹天线。器件的介质采用了石墨烯和TOPAS两种新型材料,实现可调谐极化转换和圆极化。其中TOPAS是一种很好的宽带太赫兹元件衬底材料,而石墨烯的化学势可以在0 eV和0.5 eV之间调节,使得该极化转换单元可以重建1THz(0.76THz~1.02THz)和2.5THz(2.43THz~2.6THz)波段的极化状态,在两个频段的带宽分别为0.26THz和0.17THz。圆极化天线和线极化天线的工作状态可以在0.7THz~0.75THz和0.96THz~1.04 THz切换,而不需要改变物理形状。同时论文分别对石墨烯天线、超表面和组合结构进行测试,验证了元件之间的性能不相互干扰,表明该天线在相关应用中有巨大的潜力。
A hybrid dual-frequency polarized reconfigurable terahertz antenna is designed and studied in this paper.The device adopts two new materials,graphene and TOPAS,to achieve tunable polarization conversion and circular polarization.TOPAS is a good substrate material for broadband terahertz elements,and the chemical potential of graphene can be adjusted between 0 eV and 0.5 eV,so that the polarization conversion unit can reconstruct the polarization state of 1THz(0.76THz~1.02THz)and 2.5THz(2.43THz~2.6THz)bands.The bandwidths in the two bands are 0.26 and 0.17THz respectively.The operating state of circular and linear polarized antennas can be switched between 0.7THz~0.75THz,0.96THz~1.04THz without changing the physical shape.At the same time,the graphene antenna,metasurface and combined structure are tested to verify that the performance of the components does not interfere with each other.The antenna can show great potential in related applications.
