▎ 摘　　要

NOVELTY - The system has an elongated dielectric layer mounted on a conductive plane. An elongated graphene nanoribbon element is mounted along an axis and coupled to the dielectric layer at a graphene/dielectric interface. A feeding mechanism is coupled to the conductive plane, accepts a signal that excites surface plasmon polariton waves at the graphene/dielectric interface. The graphene nanoribbon element is doped with a dopant to tune the system to predetermined surface plasmon polariton wave frequency. USE - Antenna system for providing communications between radio-frequency transceivers. ADVANTAGE - The system ensures planar geometry of graphene to easily integrate nano-antennas in advanced nano-devices with diverse applications, thus analyzing frequency response of nano-strip antennas resulting in compact antennas. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a communication system (2) a method for making a surface plasmon polariton wave antenna. DESCRIPTION OF DRAWING(S) - The drawing shows a plan view of a portion of a graphene nanoribbon. Single-atom column indexes (J1-JN) Wave vector (k) Armchair graphene nanoribbon (200)
