Abstract
Embodiments of the present invention relate to a graphene-based Rotman lenses and associated methods of formation. In some embodiments, a lens is positioned proximate to a surface of a dielectric plate. In other embodiments, the lens comprises a first lens contour positioned opposite a second lens contour. In certain embodiments, a plurality of first transmission lines extends from the first lens contour and each terminating at a particular first port. In yet still other embodiments, a plurality of second transmission lines extends from the second lens contour and each terminating at a particular second port. In some embodiments, the lens includes a composition having a polymer(s) and a three-dimensional network of individual sheets of graphene positioned within the composition. In certain embodiments, the first port and/or the second port has a width of λ/2 or less.
