Course Description: Wireless data traffic has grown exponentially in recent years due to a change in the way today's society creates, shares and consumes information. This change has been accompanied by an increasing demand for higher speed wireless communications, anywhere, anytime. Wireless Terabit-per-second (Tbps) links are expected to become a reality within the next ten years. In this context, Terahertz (THz)-band (0.1-10 THz) communication is envisioned as one of the key wireless technologies of the next decade. The THz band will help overcome the spectrum scarcity problems and capacity limitations of current wireless networks, by providing an unprecedentedly large bandwidth. In addition, THz-band communication will enable a plethora of long-awaited applications, both at the nano-scale and at the macro-scale, ranging from wireless massive-core computing architectures and instantaneous data transfer among non-invasive nano-devices, to ultra-high-definition content streaming among mobile devices and wireless high-bandwidth secure communications.

In this course, an in-depth view of THz-band communication networks will be provided. First, the state of the art and open challenges in the design and development of THz-band devices will be presented. In particular, the existing limitations and possible solutions in the design of high-speed THz-band transceivers, broadband antennas and dynamic antenna arrays will be described. A special emphasis will be given to the utilization of novel materials such as graphene, to develop compact solid-state devices for THz communications. Then, the current progress and future research directions in terms of channel modeling; physical layer design, including bandwidth-adaptive modulation, real-time channel coding, and ultra-massive MIMO transmission schemes; and, link layer solutions, including error, flow and medium access control for THz-band communication networks, will be tackled in a bottom-up approach, defining a roadmap for the development of this next frontier in wireless communication. This course will provide the students with the necessary knowledge to work in a cutting-edge research field, at the intersection of nanotechnologies and information and communication technologies.
