Sub-Terahertz (sub-THz) and Terahertz (THz) technologies, which are often referred as beyond-5G communication, are today attracting a great interest from both academia and industry. The transmission of information in the spectrum above 90GHz, up to 300GHz allows the use of huge bandwidths, from ones to tens of GHz. As the millimetre-wave communication systems will become mature with the emergence of 5G technologies, the focus of the research activities is naturally moving to the sub-THz range. The continuous increase in wireless capacity makes the bandwidth requirements always more ambitious. Ultra large bandwidths can be used for terabit-per-second (Tb/s) short-range wireless communications, or ultra-high capacity backhaul or kiosk applications, among others.
Nowadays, the sub-THz/THz techniques are far from the maturity achieved in microwave, millimetre-wave, and photonics. The key issue is that such systems cannot be implemented with existing technology especially when it comes to integrated devices. First concern is the design of high-performance reasonable-cost integrated circuits that include powerful sub-THz/THz sources, high-gain antennas, and sensitive sub-THz detectors.
In addition to those hardware considerations, the characterization and modelling of the PHY-layer components, including the propagation channel (line-of-sight, obstructed line-of-sight, and multi-paths propagation models), RF performance/constraints (e.g., phase noise) and antennas as well as network topologies are of primary importance to assess and optimize the investigated sub-THz/THz communication systems.
Note that many recent advancements with different technologies is finally closing the so-called THz gap. From one hand, we have the electronic approach, where semiconductor technologies have demonstrated record performance in terms of output power, noise figure, and power-added efficiency at sub-THz frequencies. On the other hand, in a photonic approach, optical down-conversion systems and quantum cascade lasers are rising as potential candidates for high-power high-speed THz-band communication systems.

The goal of this GDR-ISIS event, which will be held as a virtual event, is to share the recent progress made in the emerging sub-THz/THz communication domain, relying on innovative transmission and detection techniques. The event includes invited speakers giving talks on main challenges and recent progress in the field of sub-THz/THz, and dedicated short presentations on applications or technologies, selected from an open call based on abstract submissions. Academic and Industry researchers as well as PhD students are welcomed for contributions. The event will be the 20th of May, start time 9:25 and ending time at 17:30.
