论文摘要
已证明基于石墨烯的智能反射表面(GIR)提供了一个有希望的传播环境,以提高高频Terahertz(THZ)无线通信的质量。在本文中,我们使用石墨烯的材料特定参数来调整IRS入射波的反射。特别是,我们提出了一个吉兹设计模型,考虑到入射信号频率材料级别参数,例如电导率,费米级,贴片宽度,以控制通信接收器的反射幅度(RA)。我们已经获得了RA的闭合形式表达,以进行GIR的精确设计和表征,这在现有研究中是不完整的,这是由于仅包含相移。数值模拟结果通过提供关键见解来证明所提出的表征的有效性。
Graphene-based intelligent reflecting surface (GIRS) has been proved to provide a promising propagation environment to enhance the quality of high frequency terahertz (THz) wireless communication. In this paper, we characterize GIRS for THz communication (GITz) using material specific parameters of graphene to tune the reflection of the incident wave at IRS. In particular, we propose a GITz design model considering the incident signal frequency material level parameters like conductivity, Fermi-level, patch width to control the reflection amplitude (RA) at the communication receiver. We have obtained the closed-form expression of RA for an accurate design and characterization of GIRS, which is incomplete in the existing research due to the inclusion of only phase-shift. The numerical simulation results demonstrate the effectiveness of the proposed characterization by providing key insights.
