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.

Distributed MEMS Tunable Filters [PDF]
31st European Microwave Conference, 2001, 2001 This paper focus on the design of MEMS distributed tunable millimeter wave filters. A two pole filter continuously tunable in bandwidth and in frequency with constant input/output impedance is described. The center frequency can be tuned from 37.8 GHz to 40.4 GHz and the bandwidth can be changed from 1.6 GHz to 1 GHz with constant return losses.
