Recently, overcrowded spectrum in traditional microwave frequencies has motivated research and development of communications and networking in terahertz (THz) frequencies (0.1-10 THz). Traditionally, one of the main challenges with THz-band communication has been the lack of compact high-power signal sources and high-sensitivity detectors. Recently, advances in material and device technology have enabled components such as high power amplifiers, low noise amplifiers, frequency multipliers and travelling wave tube amplifiers that operates in THz frequencies.
• Present and exchange the state of the art and ongoing research activities in THz communications and networking, including device technology development, system integration, channel characterization, and network architecture and protocol design.
• Reach a consensus in the next steps towards the development THz communication links and networks in the form of challenges in research, development and operational perspectives.
• Present the findings and recommendations by the participants in meeting proceedings, and eventually in a position paper.
• Current state-of-the-art component technology and its limitations - sources, detectors, amplifiers based on solid-state and photonics-based technology as well as new materials such as 2D materials.
• Current physics-based propagation models and their limitations. Channel sounding and propagation data collection efforts. Development verifiable statistical channel for military relevant scenarios.
• High-gain antenna and antenna arrays design and architecture. Dynamic beam-forming, beam tracking and alternate path finding in case of beam blockage. Active and passive relaying and multi-hop communication schemes.
• Synchronization and medium access strategies including in-band and out-of-band link layer protocols.
• Topology control, network management and interoperability with links in legacy bands.
• Coexistence and spectrum sharing with current incumbent passive services.
