Broadband Terahertz Devices and Communication Technologies, 2nd Edition

The exponential growth of users' data traffic imposes increasingly stringent requirements on communication networks with regard to bandwidth, data rates, and diversified capabilities to support future social and industrial information exchange. The terahertz band is capable of satisfying the ultra-high bandwidth and ultra-large capacity demands of emerging scenarios, thereby facilitating advanced services such as virtual reality, augmented reality, and satellite-terrestrial communications. Furthermore, terahertz technology has also found promising applications in data center interconnection and integrated space-ground networks, reflecting its growing role in diverse high-performance communication infrastructures. This Special Issue assembles 15 peer-reviewed articles, including 2 review papers and 13 original research articles. The covered research scope involves key broadband terahertz devices, the system-level verification of terahertz communication systems, and innovative technologies at other low-frequency bands, which can also provide valuable insights and inspiration for subsequent terahertz research.
