Proposing a novel structure for the implementation of a graphene metamaterial-based tunable band pass/stop spatial THz plasmonic filter [PDF]
Scientific ReportsWe propose a tunable multi-layer graphene surface plasmonic filter in the terahertz band. In this work, we can set the filter type, operation frequency, and pass/stop bandwidth by properly selecting the chemical potential of graphene.
