A compact filtering power divider with tunable attenuation (FPDA) based on graphene nanoplates is proposed in this letter. The FPDA based on graphene nanoplates consists of three parts: the multimode resonant structure provides the field concentration and filter function, the divider structure generates the power distribution, and the graphene nanoplates loaded next to the resonator are responsible for the controllable adjustment of the concentrated electric field. Depending on the good cooperation of graphene and the filtering power divider, a novel FPDA with controllable attenuation is obtained. The measured results show that the tunable range can be tuned from −3 to −11 dB with a low reflection below −8 and 21 dB high isolation.

基于石墨烯纳米板的可调衰减滤波功率分配器


这封信提出了一种基于石墨烯纳米板的具有可调衰减（FPDA）的紧凑型滤波功率分配器。基于石墨烯纳米片的FPDA由三部分组成：多模谐振结构提供场集中和滤波功能，分配器结构产生功率分布，加载在谐振器旁边的石墨烯纳米片负责集中电的可控调节。场地。依靠石墨烯与滤波功分器的良好配合，获得了一种新型衰减可控的FPDA。测量结果表明，可调范围可在-3至-11 dB之间调节，且低反射低于-8，高隔离度为21 dB。
