This proceedings volume features reviews and original research papers that contribute to the advanced interdisciplinary studies of theories, technologies, and strategies in terahertz (THz) science and technology. Topics covered include THz sensing, detection and sources, communications, and biophysical research. The THz spectrum is crucial for applications such as body security checks, non-destructive sensing, bio-imaging, and bio-medicine. It overlaps with the characteristic fingerprints of molecular vibrations and rotations (e.g., those of proteins and DNA molecules), enabling resonant interactions with various bio-materials. Additionally, the study into high-speed modulation in the terahertz range is the holy grail for integrated photonics in high-capacity computing, attracting widespread attention from researchers engaged in the fundamental science and applications of THz. This proceedings volume is suitable for researchers and students interested in interdisciplinary research at the intersection of electromagnetics, electronics, and life sciences.

Presents latest research and technological advances by leading researcher teams Highlights terahertz sensors, detection, bioeffect, and biophysics Discusses terahertz signal sources, device, transmission, radiation, communication, radar, and imaging

Chao Chang is the receiver of the National Science Fund for Distinguished Young Scholars, the leading talent of the National Ten Thousand Talents Plan of China. He is a professor at Peking University. He was born in 1983, received his bachelor's degree in 2006 and Ph.D. in 2010 both from Tsinghua University, China and did post-doctoral research during 2011-2013 from Stanford University, the USA. He is the director of  Innovation laboratory of Terahertz biophysics. He has devoted to the research of microwave plasma and terahertz/Infrared bio-sensor and bio-effects. He is the winner of the first prize of the 2019 China's State Science Awards, the 2020 Ho Leung Ho Lee Award, the 2020 special award of China's Youth Science and Technology Awards, the 2020 Xplore Prize, the 2017 IEEE NPSS Early Achievement Award, the 2018 Tan Kah Kee Young Scientist Award, and 2018 AAPPS-DPP Young Scientist Award. He is the founding chair of the IEEE NPSS Xi’an Chapter (the 1st NPSS Chapter established in China), an IEEE senior member, the general chair of the 2018 Asia-Pacific Conference on Plasma and Terahertz Science, and the technical program chair of the 2020 47th ICOPS, the 2023 APCOPTS, and the 2024 51st ICOPS. He is also the chief scientist of China's National Scientific Innovation District, chair of China Terahertz Biophysics Committee, and chair of China Terahertz Young Scientist Committee.

Ziran Zhao is a leading talent in China's National Ten Thousand Talents Plan. He is a professor at Tsinghua University in China. Additionally, he serves as the deputy director of the National Engineering Research Center for Dangerous Articles and Explosives Detection at Tsinghua University, where he is the principal investigator of the nuclear electronics and control program. He also holds the position of vice director of the Key Laboratory of Particle Technology and Radiation Imaging, which is affiliated with the Ministry of Education of China. Zhao earned his B.S. degree in engineering physics and his Ph.D. from Tsinghua University in 1998 and 2004, respectively.

Over the past 25 years, Zhao has been actively engaged in research and development (R&D) in the fields of radiation imaging, long-wavelength photonics, and system construction. He has made several original contributions, particularly in ultrabroadband terahertz/far-infrared detection, non-contact human body security inspection, and radiation imaging intelligent perception algorithms. Zhao has established a theoretical framework for the multivariant perception of long-wavelength photons. Under his leadership, a series of domestic security inspection imaging devices have been developed. These devices have not only been exported to numerous countries but have also set international standards, thereby continuously advancing the global application of related technologies and equipment.

Weidong Hu is a professor at Beijing Institute of Technology, China. He serves as the Vice Chairman of the Chinese Chapter of the International CONASENSE Association and on the expert committee of the Radio Frequency Planning Expert Group of the Ministry of Industry and Information Technology of China. His research focuses on space terahertz detection and remote sensing and radar target characterization measurement.

Wenxin Liu is a researcher at the Aerospace Information Research Institute, Chinese Academy of Sciences, a professor at the University of Chinese Academy of Sciences, a senior member of IEEE, a fellow of IET, and the chief expert of the National Key Research and Development Program. His research focuses on terahertz power sources and high-power microwaves, with an emphasis on the study of integrated millimeter-wave terahertz power devices and multiphysics field simulation.
