Executive Summary On October 9-11, 2018, Brown University hosted an international workshop on the topic of terahertz wireless communications. This event involved many of the worlds leaders in this research field, including experts in sources, detectors, signal processing components, channel characteristics, and network architectures. The goal of this workshop was to identify the key research challenges, which would enable the realization of terahertz wireless systems. The workshop breakout sessions were organized around four theme areas electronics based sources and systems photonics-based sources and systems networks, architecture, and protocols and external devices. Each of these groups discussed various aspects of the problem, identifying specific basic research challenges. These include challenges at both the physical layer and MAC layer. At the PHY layer, the basic research needs involve everything from determining the ultimate limits of source and detector performance to the arbitrary manipulation of generated wave fronts, polarization, and spectral content. At higher layers, research is needed to achieve orders-of-magnitude improvement in sychronization, as well as network discovery, routing, and access in a highly directional network where there is no omnidirectional control broadcast signal. Preserving network security will also require basic research, to determine the optimal strategy for spread-spectrum signaling in covert directional networks with deterministic dispersive characteristics.
