Abstract

The need for higher data-rates and more ubiquitous connectivity for an ever-increasing number of wirelessly connected devices motivates the exploration of uncharted spectral bands. In this context, Terahertz (THz)-band (0.1–10 THz) communication is envisioned as a key wireless technology of the next decade. The very large bandwidth available at THz frequencies (tens to hundreds of consecutive GHz) can alleviate the spectrum scarcity problem while enabling wireless Terabit-per-second (Tb/s) links in personal and local area networks, backhaul for urban and rural areas, and even space networks. Moreover, the very small size of THz transceivers and antennas (submillimetric at THz frequencies) leads to miniature communication devices with applications in wireless networks on chip, wireless nanosensor networks, and the Internet of Nano-Things, to name a few. Nevertheless, several roadblocks need to be overcome to tap in the THz band, ranging from the lack of high-power THz sources, high sensitivity detectors, and steerable directional antenna systems, to advanced signal processing, communication, and networking techniques that can make the most of the ultra-broadband THz channel while overcoming the challenging propagation characteristics of THz waves. In this talk, the state of the art and open challenges to enable THz communication systems will be presented, with a special emphasis on innovative platforms for experimental THz research.
