摘要：

We investigated a double-clamped graphene device positioned over a planar waveguide in which propagate electromagnetic fields up to 60 GHz. Several double-clamped graphene flakes display good characteristics in enabling and disabling the propagation of high-frequency electromagnetic fields. The same characteristics were retrieved in a graphene switch based on the rapid change in the resistivity due to an applied gate voltage. Both devices are among the fastest switches, the switching time being very short less than 1 ns.
