一种动态可控的石墨烯三端口环行器
Dynamically controllable graphene three-port circulator
摘要：
提出并分析了一种新型的石墨烯基三端口环行器。组件的横截面呈现由硅层、二氧化硅层和石墨烯层组成的三层结构。平面图类似于一个普通的微波纳米带环行器，它有一个圆形的石墨烯谐振器和三个对称连接的波导。石墨烯在直流磁场的作用下垂直于其平面磁化。数值模拟结果表明，在中心频率为8.23THz的6.98频带内，隔离度为-15dB，插入损耗为-2dB。
英文摘要：
A new type of the graphene-based three-port circulator is suggested and analysed. The cross-section of the component presents a three-layer structure consisting of a layer of silicon, of silica and of graphene. In-plane figure resembles a common microwave nanostrip circulator with a circular graphene resonator and three waveguides symmetrically connected to it. The graphene is magnetized normally to its plane by a DC magnetic field. The numerical simulation demonstrates the isolation of -15 dB and insertion losses of -2 dB in 6.98 \% frequency band with the central frequency 8.23THz.
