Multi-kilometre and multi-gigabit-per-second sub-terahertz communications for wireless backhaul applications

Sub-terahertz- and terahertz-band—that is, from 100 GHz to 10 THz—communication technologies will be required for next-generation (6G and beyond) wireless communication networks. Considerable progress has been made in terahertz device technology for personal and local area networks, but there are many applications that could benefit from the large capacity of sub-terahertz and terahertz wireless links if longer communication distances were...
