“…For the time being, several alternatives to generate the plasmonic signals at THzband frequencies have been considered. For frequencies under 1 THz, standard Silicon (Si) Complementary Metal-Oxide-Semiconductor (CMOS) technology [8], Silicon Germanium (SiGe) technology [25] and III-V semiconductor technologies such as Gallium Nitride (GaN), Gallium Arsenide (GaAs), and Indium Phosphide (InP) [26] can be utilized to generate a high-frequency electrical signal. By means of a plasmonic grating structure, a SPP wave could be then launched to the metamaterial-based antennas [6].…”

The increasing demand for higher bandwidth and higher speed wireless communication motivates the exploration of higher frequency bands. The Terahertz (THz) band (0.06-10 THz) is envisioned as one of the key players to meet the demand for such higher bandwidth and data rates. However, the available bandwidth at THz frequencies comes with the cost of a much higher propagation loss. Due to the power limitations of compact solid-state THz transceivers, this results in very short communication distances of approximately one meter. In this paper, the concept of Ultra-Massive Multiple Input Multiple Output (UM MIMO) communication is introduced as a way to increase the communication distance and the achievable capacity of THz-band communication networks. The very small size of THz plasmonic nano-antennas, which leverage the properties of nanomaterials and metamaterials, enables the development of very large plasmonic arrays in very small footprints. For frequencies in the 0.06-1 THz range, metamaterials enable the design of plasmonic antenna arrays with hundreds of elements in a few square centimeters (e.g., 144 elements in 1 cm 2 at 60 GHz). In the 1 to 10 THz band, graphene-based plasmonic nano-antenna arrays with thousands of elements can be embedded in a few square millimeters (e.g., 1024 elements in 1 mm 2 at 1 THz). The resulting arrays can be utilized both in transmission and in reception (e.g., 1024x1024 UM MIMO at 1 THz) to support di↵erent modes, from razor-sharp UM beamforming to UM spatial multiplexing, as well as multi-band communication schemes. After introducing the main properties of plasmonic nano-antenna arrays, the working modes of UM MIMO are presented, and preliminary results are provided to highlight the potential of this paradigm. Finally, open challenges and potential solutions to enable UM MIMO communication are described.

“…However, many recent advancements with di erent technologies is finally closing the so-called THz gap. For example, on the one hand, in an electronic approach, III-V semiconductor technologies have demonstrated record performance in terms of output power, noise figure, and power-added e ciency at sub-THz frequencies, and are quickly approaching the 1 THz [9,14]. On the other hand, in an optics approach, Quantum Cascade Lasers are rising as potential candidates for high-power THz-band signal generation [12,16].…”

Terahertz (THz) band (0.1-10 THz) communication is envisioned as a key technology to address the explosive growth in mobile data in recent years and the demand for high speed wireless communications. Major recent advances in device technologies are finally closing the THz gap and, thus, bringing this networking paradigm closer to reality. A general channel model is essential in designing and simulating communication techniques for the THz band. In this paper, we develop a stochastic multipath channel model for THz band communication for bounded area applications. Specifically, an analytical model for the number of single bounce multipath components and the power delay profile in a rectangular deployment scenario is derived, considering the density of obstacles, variable geometry of the rectangle, the signal blocking by obstacles and the propagation properties of THz signals. The model is independent of the physical layer technology and can be tailored to di erent application scenarios. Extensive simulation results are provided and utilized to validate the developed analytical model. CCS CONCEPTS • Mathematics of computing Mathematical analysis; • Networks Mobile ad hoc networks;

In this paper, a graphene-based plasmonic phase modulator for Terahertz band (0.1-10 THz) communication is proposed, modeled and analyzed. The modulator is based on a fixed-length graphene-based plasmonic waveguide, and leverages the possibility to tune the propagation speed of Surface Plasmon Polariton (SPP) waves on graphene by modifying the Fermi energy of the graphene layer. An analytical model for the modulator is developed starting from the dynamic complex conductivity of graphene and a revised dispersion equation for SPP waves in gated graphene structures. By utilizing the model, the performance of the modulator is analyzed in terms of symbol error rate when utilized to implement a M-ary digital phase shift keying modulation. The model is validated by means of electromagnetic simulations, and numerical results are provided to illustrate the performance of the modulator.
