Abstract: Embodiments of the present invention relate to graphene-based Rotman lenses. In an embodiment, a lens is formed on a surface of a dielectric plate. The lens comprises a composition having individual sheets of graphene. The lens includes a plurality of first transmission lines extending from a first lens contour and a plurality of second transmission lines extending from a second lens contour. The plurality of first transmission lines each terminate at a first port. The plurality of second transmission lines each terminate at a second port. The first contour and the second contour are positioned opposite each other. The first port and/or the second port has a width of λ/2 or less. The individual graphene sheets form a three-dimensional interconnected network within the composition.
