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.
