Abstract
Various emitters and emitter systems are disclosed. For instance, in various embodiments, an emitter can comprise a substrate, an insulator bonded to the substrate, a graphene layer bonded to the insulator, and a first electrical contact and a second electrical contact. The first electrical contact can be bonded over a first portion of the graphene layer, and the second electrical contact can be bonded over a second portion of the graphene layer. The graphene layer electrically couples the first electrical contact and the second electrical contact and is configured to receive the application of a pulsed input voltage between the first electrical contact and the second electrical contact and to radiate radio frequency (RF) energy. An emitter system can comprise a plurality of emitters, each disposed on a single integrated circuit.
