Abstract

We propose and discuss a novel micro-machined reconfigurable terahertz (THz) filter based on graphene. The key components are the periodic metal ring with several gaps where active graphene strips are placed. We can easily adjust the resonance frequency of the terahertz filter by varying a couple of parameters such as the inner and outer radius of the metal ring, the gap, the number of graphene layers, and by dynamically varying the conductivity of each graphene layer. This work explains the principle of operation of the device, its design based on numerical simulations, its fabrication process, and also presents experimental results.
