摘要

本文提出了一种由6层组成的1太赫兹石墨烯-金属杂化透射超表面。通过施加直流偏置电压，透射波的360°$360{}^{\circ}$相位变化得到。此外，还设计了一种用于在三维方向上控制铅笔光束的发射阵列，使用所提出的单元格。采用贴片结构的发射阵列设计比采用缝隙结构的发射阵列设计具有更小的面波和边缘衍射，从而降低了旁瓣电平和更宽的转向角范围。获得的最大增益为23.5 dB。设计的波束导向为θ = 0°～ 45°$\theta =0{}^{\circ}-45{}^{\circ}$和φ = 0°～ 360°$\phi =0{}^{\circ}-360{}^{\circ}$。

Fully Controllable Beam-Steering 1-THz Transmitarray Using Graphene–Metal Hybrid Metasurface

In this paper, a 1-THz graphene–metal-hybrid transmissive metasurface is proposed, which consists of six layers. By applying a dc biasing voltage, over a $360 °$ -phase variation of the transmitted wave is obtained. Also a transmitarray for steering a pencil-beam in the 3D direction is designed using the proposed unit cell. Using the patch type structure in the transmitarray design has less surface wave and edge diffraction, in comparison with slot type transmitarray design, which leads to lower side lobe level and a wider steering angular rang. The obtained maximum gain is 23.5 dB. The designed beam steering is in $θ = 0 ° - 45 °$ and $ϕ = 0 ° - 360 °$ .
