论文摘要
在本文中，我们在基于石墨烯的圆柱形结构中分析了表面等离子体偏振子（SPP）。在一般的波导中，每个石墨烯层都被两种各种陀螺仪材料所包围。 SPP波的现场贡献得出了新的闭合关系。作为一种特殊情况，本文考虑了带有双层石墨烯的陀螺仪波导带有双层石墨烯。对于设计的结构，在33 THz的频率下，B = 2 t和μC= 0.7 eV的绩效（FOM）的图（FOM）的数字为51。证明所研究的波导的FOM通过调整化学势和磁性偏置而变化。利用陀螺介质与石墨烯层一起利用新的有前途的平台，用于在中红外地区设计和制造新型等离子设备。
In this paper, we analytically study Surface Plasmon Polaritons (SPPs) in graphene-based cylindrical structures with gyroelectric layers. In the general waveguide, each graphene layer is surrounded by two various gyro-electric materials. New closed-form relations are derived for the field contributions of SPP waves. As a special case, a gyro-electric cylindrical waveguide with double-layer graphene is considered in this article. For the designed structure, the figure of merit (FOM) of 51 is reported for B= 2 T and μc=0.7 eV, at the frequency of 33 THz. It is demonstrated that the FOM of the studied waveguide is varied by tuning the chemical potential and the magnetic bias. Harnessing the gyro-electric media together with graphene layers will open a new promising platform for the design and fabrication of novel plasmonic devices in the mid-infrared region.
