From July 13 to 27, the 2nd International Terahertz Summer School was held at Beihang University Hangzhou International Campus. As one of the brand activities of the Beihang International Summer School (BISS), this event was jointly organized by the International Terahertz Science and Technology Innovation Centerand the International Education Center of Hangzhou International Innovation Institute of Beihang University (H3I).

More than 200 teachers and students from over 40 top institutions in nearly 30 countries worldwide gathered to engage in learning, exchange, and discussion centered around terahertz science, technology, and applications. The institutions included Imperial College London (UK), Max Planck Institute (Germany), Nanyang Technological University (Singapore), Lancaster University (UK), Universitat Politècnica de València (Spain), Université Savoie Mont Blanc (France), Utrecht University (Netherlands), United Arab Emirates University, Technical University of Denmark, Goethe University Frankfurt (Germany), Commonwealth Scientific and Industrial Research Organisation (Australia), Tsinghua University, Zhejiang University, Fudan University, Nankai University, Beijing Normal University, and Beijing University of Posts and Telecommunications.

During the course and lecture sessions, 21 renowned scholars from leading research institutions around the world delivered insightful presentations. The courses combined academic theory with research experiences, enabling participants to systematically grasp the cutting-edge advancements in the terahertz field and gain inspiration from the experts' scientific exploration journeys. In the specialized lectures, experts delved into the latest breakthroughs in terahertz light source technologies, detection technologies, modulation technologies, and other areas, while also exploring their application prospects and development trends in fields such as aerospace, communication radars, and biomedical applications.

Throughout the event, a variety of exchange and competition activities were in full swing. During the ice-breaking activities, Chinese and international participants actively interacted and bravely showcased themselves. At the graduate student forum, participants eagerly shared their academic achievements, sparking innovative ideas through collisions of thought. In the speech contest, participants recounted their personal research stories, which not only honed their presentation skills but also deepened mutual understanding.

At the closing ceremony, Professor Jean-Louis Coutaz, Professor Rostislav Mikhaylovskiy, and Professor Aparajita Bandyopadhyay delivered speecheson behalf of the lecturers invited by the International Terahertz Science and Technology Innovation Center. They presented honorary certificates to outstanding participants and organized representatives of teachers and students to share their reflections on the event.

During the cultural experience activities, participants visited the Liangzhu Museum, the Urban Planning Exhibition Hall, and other venues, immersing themselves in the unique charm of the Chinese civilization, which built bridges for cross-cultural exchanges through the collision of ancient and modern wisdom.

The summer school provided a high-quality platform for young scholars worldwide in the terahertz field to exchange academic ideas and broaden their academic horizons.Participants not only acquired cutting-edge knowledge but also forged friendships with like-minded peers, jointly exploring the infinite possibilities of terahertz technology.In the future, the International Terahertz Science and Technology Innovation Center will remain committed to promoting international exchanges and cooperation in the terahertz field, creating more high-quality learning opportunities, and facilitating broader breakthroughs and applications of terahertz technology in more fields.
