In recent years, he has led and undertaken multiple national-level terahertz projects, including the National Key R&D Program of the Ministry of Science and Technology, the National Basic Research Program (“973” Program), and key projects, general projects, and the Young Scientists Fund of the National Natural Science Foundation of China. He has published more than 90 SCI papers in international and domestic journals such as Physical Review Letters and Carbon, and has been granted more than 20 invention patents. He has been invited many times to attend international and domestic academic conferences, where he has delivered plenary talks and served as session chair. As conference chair and executive chair, he has organized the National Terahertz Science & Technology Annual Conference and the Terahertz Session of the National Conference on Laser Technology and Optoelectronics, and he served as Program Committee Chair of the 46th International Conference on Infrared, Millimeter, and Terahertz Waves. In basic research, he was among the first internationally to propose combining free electrons with surface plasmon polaritons to generate electromagnetic radiation. The theoretical results were published in Physical Review Letters and were highly praised by Nature Physics. In recent years, he has continued this research and further proposed the direction of terahertz quantum electromagnetics: quantizing Maxwell’s equations to describe electromagnetic fields excited by free electrons, using quantum mechanical theory to describe quasiparticles, and considering the interaction between free electrons and quasiparticles to establish the Schrödinger equation within the theoretical framework of terahertz quantum electromagnetics. This approach is used to study the physical process by which free electrons excite quasiparticle polaritons to generate terahertz radiation, thereby developing terahertz polariton vacuum electronic radiation sources. This theoretical research has been supported by the Basic Science Center Project of the National Natural Science Foundation of China and the Ministry of Science and Technology National Key R&D Program project “Terahertz Radiation Research Based on Quasiparticle Polariton Excitation,” and early research results have been published in first-quartile journals such as Carbon and Photonic Research. In device development, we proposed miniaturized vacuum electronic devices based on Smith-Purcell superradiance, and proposed and developed diffraction radiation devices based on the mechanism of Smith-Purcell superradiance generated by dual electron beams and subwavelength hole array structures. Through structural coupling, the dual electron beams greatly reduce the start-oscillation current of the device and improve interaction efficiency. The related devices can achieve an output power of 500 mW at 0.3 THz, meeting the demands of terahertz applications. The research results were published in IEEE Transactions on Electron Devices. In terahertz applications, using fully domestically produced equipment, we successfully realized a terahertz near-field microscopy system, THz-SNOM. This system is the world's first terahertz near-field imaging system based on vacuum electronic devices. It effectively solved the signal-to-noise ratio problem of terahertz near-field systems and achieved terahertz imaging with a resolution of 20 nm. It has been applied in multiple biomedical scenarios such as virus observation and tooth demineralization, and it broke the monopoly of international manufacturers on such instruments. Using this instrument, we have conducted research on terahertz biomedicine, cultural heritage protection, and non-destructive testing (NDT). Among them, the biomedical research was supported by the Transformative Technology Project "Key Mathematical Problems and Applications in Terahertz Medical Imaging and Diagnostic Systems" under the National Key R&D Program. Related Activities In September 2018, under the leadership of Academician Liu Shenggang, as a core member of the terahertz team, led faculty and students to Nagoya, Japan to participate in the 43rd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz 2018). Many faculty and students gave oral and poster presentations. More importantly, representing Academician Liu Shenggang as the bid presenter, won the right for China to host the 46th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz 2021). This was the first time the conference was held in Chengdu, and the fourth time it was held in China, following Beijing (2000), Shanghai (2006), and Hong Kong (2015). In May 2019, I led PhD student Zhang Tianyu from the team to Munich, Germany, to participate in the first International Nanoanalytics Workshop organized by Neaspec (Attocube), a well-known company in the international nanoanalysis field. We shared our laboratory's latest experimental progress and research ideas with leading international scholars (who have published in top-tier journals such as Nature and Science), and made substantial progress. In June 2019, as a core member of the terahertz team, I led faculty and students of the team to Shanghai Hongqiao to participate in the 6th National Academic Annual Conference on Terahertz Science and Technology, and as the executive chair of the conference, successfully hosted the event. At the conference, I invited well-known scholars working abroad, including Dr. Qianchun Weng of RIKEN in Tokyo, Japan, and Associate Professor Ruonan Han of MIT, to attend and deliver invited plenary talks, which won widespread praise from experts and scholars. In September 2019, as a core member of the terahertz team, I led faculty and students of the team to Paris, France, to participate in the 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz 2019), where several team faculty members and students delivered oral and poster presentations. Since the outbreak of COVID-19 in early 2020, although opportunities for international exchange and international education have been greatly limited, I have still made some positive contributions in international exchange and education. In November 2020, as a core member of the terahertz team, I led faculty and students of the team to participate online in the 45th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz 2020), originally scheduled to be held in Buffalo, USA, where several team faculty members and students delivered oral and poster presentations. From August 30 to September 3, 2021, IRMMW-THz 2021 was successfully held in Chengdu. During the three-year preparation cycle, as co-chair of the conference program committee, I invited 90 authoritative scholars and experts from around the world in specialized research fields of infrared, millimeter-wave, and terahertz science to form the review committee, and carried out rigorous and orderly manuscript review and selection, fully ensuring and implementing the high standards and high caliber of this top-tier conference. Meanwhile, we responded flexibly to the changing COVID-19 situation, worked with the local organizing committee to overcome all difficulties, and ultimately held the conference in an innovative online format combining Whova and Zoom. The conference brought together more than 1,370 scholars and industry experts who registered online, opened a new chapter following the 2019 Paris conference, and won high appreciation from the international committee and participants worldwide. The conference also provided a valuable reference and support for subsequent IRMMW-THz conferences and other international conferences held in Chengdu. IRMMW-THz2021 is the highest-profile and most influential international conference in the infrared, millimeter-wave, and terahertz fields ever held in Sichuan Province. The hosting of the conference significantly enhanced the international influence of Sichuan and Chengdu in the infrared, millimeter-wave, and terahertz fields, spurred the development of related industries, further improved the level of opening-up and international visibility, and laid a solid foundation for attracting more renowned universities, innovation platforms, research institutions, and large enterprises to Chengdu to establish information-industry R&D centers, branches, and headquarters bases, and to carry out diverse forms of cooperation with Chengdu in R&D, manufacturing, and services. In October 2021, with strong promotion and sustained coordination, Wang Yueying, a doctoral student in the terahertz team, went to the University of Colorado Boulder to begin a two-year joint doctoral training program. Her co-supervisor is Markus Raschke, an internationally renowned scholar in infrared near-field optics. At present, Wang Yueying is actively carrying out related experimental work and has already made certain research progress. For the 24th IEEE International Vacuum Electronics Conference (IVEC 2023), to be held in Chengdu in April 2023, we serve as Local Organizing Committee Chair and Program Committee Reviewer, and conference preparations are now proceeding in an orderly manner.
