Abstract
A voltage-tunable phase shifter comprising a conducting line and a ground electrode separated by a layer of dielectric material, the phase shifter configured to generate an electric field when a potential difference is applied between the conducting line and ground electrode, the electric field configured to change the phase of an electromagnetic signal propagating along the conducting line, wherein the ground electrode comprises graphene, and wherein the change in phase is dependent upon the strength of electric field and can be controlled by varying the potential difference between the conducting line and the ground electrode.
