Graphene is the most notable among carbon-based materials and it has been greatly studied. One of the most important properties of graphene is its tunable conductivity. The electron mobility of graphene is varied by a DC voltage causing a change in its electrical conductivity. The variation of the electrical conductivity is valid over a large frequency band from DC up to millimeter waves. It makes graphene suitable for a wide range of different applications. The electrical conductivity of multilayered graphene just like monolayer graphene can be tuned by the help of a DC bias voltage. Several tunable passive microwave components were designed based on lab grown multilayered graphene. Recently commercial graphene was used to design microwave tunable attenuators, phase shifters and reconfigurable antennas.

Abstract: | Graphene is the most notable among carbon-based materials and it has been greatly studied. One of... the most important properties of graphene is its tunable conductivity. The electron mobility of graphene is varied by a DC voltage causing a change in its electrical conductivity. The variation of the electrical conductivity is valid over a large frequency band from DC up to millimeter waves. It makes graphene suitable for a wide range of different applications. The electrical conductivity of multilayered graphene just like monolayer graphene can be tuned by the help of a DC bias voltage. Several tunable passive microwave components were designed based on lab grown multilayered graphene. Recently commercial graphene was used to design microwave tunable attenuators, phase shifters and reconfigurable antennas. | |
