摘要

本文提出了一种基于体Dirac半金属（Bulk Dirac Semimetal，BDS）的动态超材料结构极化偏转器.与传统的极化偏转器不同，该偏转器可以通过改变费米能级来动态控制偏振转换率和不对称传输.模拟结果表明，当BDS的费米能级调整为90 meV时，偏转器的偏振转换率在1.085~1.872 THz频率范围内都保持在90%以上（带宽为0.787 THz），在1.159 THz处偏振转换率达到峰值98%.该偏振转换器的不对称传输参数在1.229~1.831 THz大带宽范围内大于60%.本文还研究了偏振旋转角、椭圆度角、表面电流和电场分布情况以阐明该器件的极化转换特性和物理机制；通过施加栅极电压控制BDS费米能级，实现了对该极化偏转器的偏振转换率以及不对称传输的动态调谐.该极化偏转器的可调谐不对称传输特性，为基于动态不对称传输所设计的多路复用器、太赫兹二极管等设备的制造提供了新的思路.

Abstract

This paper proposes a dynamic metamaterial structural polarization converter based on bulk Dirac semimetal (BDS). Different from the traditional polarization converter

the polarization conversion ratio and asymmetric transmissions of this polarization converter can be adjusted by Fermi level. The simulation results show that when the Fermi level of BDS are adjusted at 90 meV

the polarization conversion ratio is greater than 90% in the frequency range of 1.085~1.872 THz (Bandwidth is 0.787 THz). The polarization conversion ratio is peaked at 98% at the 1.159 THz. The asymmetric transmissions of this polarization converter is greater than 60% in the big frequency range of 1.229~1.831 THz. BDS can be controlled by Fermi energy

that explained the control mechanism of polarization conversion rate and the asymmetric transmission. The polarization rotation angle

ellipticity angle

surface current and electric field distribution are studied to clarify the physical mechanism of polarization deflection. By applying gate voltage to control the Fermi level of BDS

the dynamic tuning of polarization conversion rate and asymmetric transmission of the polarization converter is realized. The tunable asymmetric transmission characteristics of this polarization converter provide a new idea for the manufacture of multiplexers

THz diodes and other equipment.
