On the afternoon of July 27, 2021, at the invitation of the School of Microelectronics and Communication Engineering, Chongqing University,  Professor Yang Kun from the University of Electronic Science and Technology of China came to our school for academic exchanges. Professor Yang Kun is also the Chair Professor of the School of Computing Science and Electronic Engineering of the University of Essex in UK, a member of the European Academy of Sciences, and a member of the European Academy of Sciences and Arts. His main research interests include: wireless network and communication, future Internet technology, wireless data and energy integrated communication network, communication and computing integration technology, etc. He has published more than 400 papers in international core journals and major conferences, and authorized more than 20 international and domestic invention patents. He is selected as one of the “Top 2% Global Scientists” issued by Stanford University in 2020, and has been cited nearly 10,000 times by Google Scholar. Founding member of IEEE InterCloud (cloud interconnection) and one of the six executive standing committees, reviewing expert of WMC GLOMO Award of World Mobile Congress, associate editor of several IEEE journals, outstanding speaker of IEEE Communications Association (2020-2021), and won best paper awards in IEEE mainstream conferences.

Professor Yang Kun’s academic lecture is titled "Energy Self-sustainability in Future Wireless Networks". The lecture report was hosted by Associate Professor Cai Yueping of the School of Microelectronics and Communication Engineering. More than a dozen young teachers and students, including Associate Professor Jian Xin and Researcher Chen Chen participated and actively asked questions and discussed. First of all, Associate Professor Cai Yueping presided over the report and expressed a warm welcome to Professor Yang Kun's arrival. Professor Yang Kun first gave a brief introduction to the energy transmission technology of wireless induction charging, and combined his rich research experience over the years to share his understanding of the development status of radio frequency energy transmission. After that, Professor Yang Kun made a comprehensive interpretation of the various solutions and existing problems of the trade-off design of the wireless data-energy integrated transmission currently carried out by his team, such as radio frequency energy transmission, information coding control and information modulation control, etc. Furthermore, Professor Yang Kun introduced his team's work in related research and design, and showed his team's experimental results and latest research progress in wireless energy communication systems. In addition, Professor Yang Kun also briefly looked forward to the design of digital-energy simultaneous transmission signals based on WiFi, software radio and 5G. At the end of thelecture, Professor Yang Kun conducted extensive exchanges with Associate Professor Cai Yueping and other teachers and students, and answered questions and discussions on the system implementation details and restrictions raised by the audience. The exchange ended smoothly in an atmosphere of enthusiastic academic discussion.
