数值分析了太赫兹辐射在石墨烯基纳米贴片天线上的散射。计算了不同厚度的硅和二氧化硅衬底支撑的纳米天线的消光截面。太赫兹波段的散射共振被认为是由石墨烯薄膜支撑的表面等离子体激元的法布里-珀罗共振。数值结果表明，通过静电偏置，天线具有很强的可调性，为设计可调谐的石墨烯基纳米天线开辟了新的前景。这些天线被设想为能够实现纳米级的无线通信。(C)2012爱思唯尔B.V.保留所有权利。
The scattering of terahertz radiation on a graphene-based nano-patch antenna is numerically analyzed. The extinction cross section of the nano-antenna supported by silicon and silicon dioxide substrates of different thickness are calculated. Scattering resonances in the terahertz band are identified as Fabry Perot resonances of surface plasmon polaritons supported by the graphene film. A strong tunability of the antenna resonances via electrostatic bias is numerically demonstrated, opening perspectives to design tunable graphene-based nano-antennas. These antennas are envisaged to enable wireless communications at the nanoscale. (C) 2012 Elsevier B.V. All rights reserved.
