Flexible and Dynamically Tunable Attenuator Based on Spoof Surface Plasmon Polaritons Waveguide Loaded With Graphene

摘要

This paper reports on a flexible and dynamically tunable spoof surface plasmon polariton (SSPP) attenuator for the first time. It consists of an SSPP waveguide and a graphene sandwich structure (GSS). Due to the flexibility of both the GSS and the SSPP wa
