Education and Experience
Chao-Hai Du received the B.S. degree in electronics from the University of Electronic Science and Technology of China (UESTC), Chengdu, China, in 2005, and the Ph.D. degree in physical electronics from the University of Chinese Academy of Sciences, Beijing, China, in 2010. He worked as a postdoctoral researcher in Tsinghua University, Taiwan, between 2011 and 2013. He is currently a Research Professor and a doctoral supervisor with Department of Electronics, Peking University, Beijing, China.
Program Research Works
He worked on the development of millimeter-wave gyroklystrons and gyro-TWTs between 2006 and 2011. And then his research interests were gradually changed into harmonic gyrotrons and frequency tunable gyrotrons in terahertz band. He is the one who understands the theory and simulation of both gyrotron amplifiers and oscillators in depth, who manages the key technologies, including magnetron injection gun, axis-encircling electron gun, broadband input coupler, triple-disc sappire output window, diamond Brewster window, broadband multi-mode quasi-optical mode-convert antenna, who is professional in design, fabrication and measurement of millieter-to-terahertz-wave gyrotron devices. He is currently developing a 1-THz harmonic gyrotron with superconducting magnet and a whispering-gallery-mode frequency-tunable quasi-optical gyrotron with a compact pulse magnet. He has been invited to publish a monograph entitled The Millimeter-Wave Gyrotron-Traveling-Wave-Tube Amplifiers in Springer and has published more than 40 first-authored or corresponding-authored SCI journal papers. He has 22 authorized invention patents.
He has been awarded the talent programs of Excellent Young Scholars from National Natural Science Foundation of China and Newton Advanced Fellowship from The Royal Society of London, UK.
Teaching Achievements
He has opened courses related to Circuit Analysis, Microwave Engineering, and Terahertz Science and Technology for undergraduate and graduate students in Peking University since 2013. He won Excellent Teaching Team Award, The First Prize of Teaching Reform Achievement Award, Outstanding Teacher of the Year. Some of his Ph. D graduate students won Outstanding Graduates of Beijing, Vacuum Science Doctoral Excellent Thesis Scholarship of Chinese Vacuum Society, Excellent Conference Paper Awards, and so on.
Vacuum Electronics Young Scientist Award 2021
For publishing a monograph related to gyro-TWTs theory and enginering, improving the theory for modeling dielectric-loaded gyro-TWTs, proposing a solution to realize high current axis-encircling electron beams for harmonic gyrotron application, and proposing innovative schemes for developing frequency-tunable THz gyrotrons.
