Terahertz (THz)-band (0.1 - 10 THz) communication is envisioned as a key wireless technology to satisfy the need for higher wireless data rates in denser networks. Several ongoing approaches are being considered to overcome the grand challenge of the THz band, i.e., the limited communication distance. Among others, the use of new 2D nanomaterials such as graphene to create novel plasmonic devices that operate directly in the THz range and can be densely packed has been proposed. This paper presents a novel THz plasmonic array architecture which leverages the properties of graphene to greatly simplify its design and operation. Each element of the plasmonic array is an independent front-end, consisting of an on-chip plasmonic source, modulator and antenna. The advantages of this array architecture over conventional array architectures are discussed. The trade-offs in the design of the front-end and the array are exhaustively studied in transmission. The ability to perform continuous dynamic beamforming is presented. A new tailored algorithm is developed for beamforming weight selection. Extensive numerical results are provided to demonstrate the functionality of the array for dynamic beamforming and increased power output.
