Abstract
[ENG]The exceptional electrooptical, thermal, and mechanical properties of graphene has motivated an enormous interest from
the scienti c community in a wide variety of elds in recent years. In particular, the capability of mono- and multilayer
graphene to support highly con ned recon gurable surface plasmon polaritons in the terahertz (THz) and infrared
regime has motivated an explosive growth of graphene plasmonics, a discipline which is paving the way towards fully
integrated THz transceivers and sensing systems. In this project, we rst present the novel design and analysis of planar
recon gurable THz lters hosted in graphene nanoribbons, which are e ciently designed taking advantage of the quasistatic
nature of graphene surface plasmon polaritons (SPPs) in nanostructures and graphene's eld e ect. The proposed
lters are highly miniaturized and present recon guration capabilities not possible with other technologies in the THz
band. Spatial dispersion in graphene sheets ...
