摘要

在这项贡献中,石墨烯的静电可调性被用于制造紧凑而有效的微波滤波器,即场衰减器。在中断的微带线的气隙上放置一毫米大小的石墨烯贴片,并通过高阻抗线施加的静电偏置进行调谐,即依次在中心频带频率上与微波滤波器解耦。结果表明,滤波器响应强烈依赖于外部偏置,这不仅有望在质量,体积和功耗方面实现前所未有的性能,而且还可能将石墨烯集成到各种标准微波器件中。

On the use of electrostatically doped graphene: Analysis of microwave attenuators
In this contribution, the electrostatic tunability of graphene is exploited in order to fabricate compact and effective microwave filters, namely field attenuators. A graphene patch of millimeter size is placed across the air gap of a discontinued microstrip-line, and tuned by means of an electrostatic bias applied by a high impedance line, that is, in turns, de-coupled from the microwave filter at center-band frequency. Results show that the filter response is strongly dependent on the external bias, and this promises not only for unprecedented performances, in terms of mass, volume and power consumption, but also for possible integration of graphene in a wide class of standard microwave devices.
