摘要

在这项工作中，我们首次提出了一种基于有效表面等离子激元(ESPPs)和石墨烯的新型动态可调谐衰减器，频率约为5.6 GHz。该衰减器是通过在ESPPs波导上沉积扁平石墨烯夹层结构(GSS)来设计的，以简化制造。通过施加适当的偏置电压，可以调节石墨烯的表面阻抗，并且衰减也可以在3dB到20dB之间动态调节。

Dynamically Tunable Attenuator Based on Effective Surface Plasmon Polaritons and Graphene

In this work, we firstly proposed a novel type of dynamically tunable attenuator based on effective surface plasmon polaritons (ESPPs) and graphene at around 5.6 GHz. This attenuator is designed by depositing a flat graphene sandwich structure (GSS) on the ESPPs waveguide to simplify fabrication. By applying an appropriate biased voltage, the surface impedance of graphene can be adjusted, and the attenuation can also be tuned dynamically from 3dB to 20dB.
