01 Dedication, the beginning of progress
As a student party member, Chang Mingyang has the consciousness of strengthening theoretical study and often reflects on himself. Taking party building as an opportunity and "three good and three haves" team building as the goal, he pays attention to the development and construction of the party branch of the scientific research group, and is committed to increasing the vitality of the scientific research team, leading the development of the team, and creating a good scientific research environment for the teachers and students of the team.
During his tenure as a member of the Party Branch of the Zhuoxing Ruisi Scientific Research Group, he organized the team of teachers and students to study the spirit of the meeting and held regular organizational life meetingsArm the mind with the party's innovative theory, guide the practice, and promote the team's scientific research work, so that the team members not only have a solid professional foundation, but also adhere to a clear political orientation. In 2022, Chang Mingyang's team participated in the selection of the 7th "Three Good and Three Haves" graduate student mentoring team, as the student leader of the "Three Good and Three Haves" team building, he set an example, gave full play to the vanguard and exemplary role of party members, planned and organized activities such as "A Series of Activities to Commemorate the 102nd Anniversary of the May Fourth Movement" and "Changjin Lake" Movie Watching, leading the team teachers and students to relive the red spirit, enrich the team's scientific research life, and enhance the cohesion and combat effectiveness of the laboratory team; In order to commemorate the revolutionary martyr Comrade Li Bai, he led the team of teachers and students to adapt the stage play "The Eternal Wave", with the joint efforts of the team teachers and students, the team finally won the title of the 7th "Three Good and Three Haves" Graduate Tutoring Team, and won the "Best Style Award" and "Best Popularity Award" in the exhibition.

Chang Mingyang always strictly demands himself with the standards of an excellent Communist Party memberWhile doing their own work, they pay more attention to serving their classmates. During his tenure as a teaching assistant for undergraduate students, in addition to being responsible for the academic Q&A, software use and tutoring of undergraduate students, he also organized the members of the Party branch of Zhuoxing Ruisi Research Group to go to the South Campus to carry out the party day activity with the theme of "I do practical things for teachers and students" on the South Campus, and provided one-on-one guidance on issues such as undergraduate students' postgraduate entrance examinations, public examinations and work, and strengthened the learning exchanges between party members of the branch and undergraduatesDo a good job in the construction of the style of study. During his tenure as a teaching assistant, the team won the honorary title of "Outstanding Undergraduate Mentoring Team". In addition, in order to make the new students feel at home in the new learning environment, the party branch of the scientific research group organized and planned an orientation party, so that each student can better familiarize themselves with the development history, employment situation and research direction of the scientific research teamEnables new students to quickly integrate into the team and lay a solid foundation for postgraduate study.
Undergraduate academic guidance courses are taught online and offline.
Organize members of student party branches to carry out themed party day activities.
Organize student party branches to carry out orientation parties.
02 Facing demand and serving the country
As a scientific research worker, Chang Mingyang knows that serving the country with science and technology is one of the best patriotic performances. During his master's degree, he came into contact with the research direction of wireless power transmission technology, which was rated as one of the top ten scientific research directions that will bring great changes to human production and life by the American "Technology Review" magazine, which is highly strategic and groundbreaking, and is of great significance for promoting the national energy revolution and scientific and technological innovation. So he applied to his supervisor to take wireless power transmission technology as his research direction. In order to enter the state of scientific research as soon as possible, he insisted on reading the literature every day and reported the progress of scientific research to his supervisor in stages. After the state released the relevant key research projects, Chang Mingyang's research group was fortunate to undertake the research of the State Grid frontier exploration, the national key research and development plan and other projects, and he also started his own scientific research journey.
In 2021, he participated in the State Grid Frontier Exploration Project as a student leaderThe use of metamaterial antennas and high-power microwave rectifier networks has achieved the first kilowatt-level wireless power transmission experiment in China, with a transmission distance of 20 meters, reaching the world-class advanced level. The achievement has been reported by "Science and Technology", "China", "State Grid News", Sohu.com and "Key Laboratory of Ultra-high-speed Circuit Design and Electromagnetic Compatibility of the Ministry of Education" and other institutions, and has been reported by the National Energy Administration. This technology can be used as an important auxiliary and supplement to the traditional wired transmission network, and can play an important role in some special scenarios where the wired transmission is limited, such as continuous power supply for high-altitude drones and aerial work platforms, charging of wireless sensor networks, and power supply under special geographical conditions such as islands, canyons, and deep mountains. In addition, in emergency conditions such as natural disasters or special emergency repairs, microwave transmission can be used to quickly restore power supply to disaster areas or power outage areas; Miniaturized portable microwave wireless transmission devices can also be used to supply power to high-capacity temporary user loads.

The results were reported by the State Grid News of China and the National Energy Administration.
From 2021 to 2022, he participated in the National Key R&D Program "Research and System Preparation of Key Microwave Wireless Power" project as a student leader, and designed a wireless power transmission transceiver system based on focused reflection metasurface, with an operating frequency of 58 GHz, transmission distance of 10 meters, transmit power of 5W. By converging the power to one point, the electromagnetic impact on the surrounding environment is effectively reduced, and after continuous debugging and testing, the measured effect of lighting a small lamp at a distance of ten meters away has been successfully realized, and the system is in good working conditionThe results have obtained the CNAS national certification and are applied to the microwave emergency energy transmission equipment of the Ministry of Public Security, which can provide solutions for many special application scenarios of wireless charging.
