Wen-Jun Lu
Nanjing University of Posts and Telecommunication
Wen-Jun Lu (IEEE/CIE Senior Member) was born in Jiangmen, Guangdong, China, in 1978. He received Ph.D degree in electronic engineering from the Nanjing University of Posts and Telecommunications (NUPT), Nanjing, China, in 2007. He has been a Professor with the Jiangsu Key Laboratory of Wireless Communications, NUPT, since 2013. His research interests include antenna theory, antenna design, antenna arrays, and wireless propagation channel modeling. He has advanced the generalized odd-even mode theory (GO-EMT), established a unified theoretical framework for all resonant elementary antennas under multi-mode resonance, and developed the mode synthesis antenna design approach (MSADA). He has invented the design approach to planar endfire circularly polarized antennas (PECPAs). He is the translator of the Chinese version The Art and Science of Ultrawideband Antennas (by H. Schantz). He has authored and co-authored four books, Antennas: Concise Theory, Design and Applications (in Chinese, 2014), its 2nd edition of Concise Antennas (in Chinese, 2020), Multi-mode Resonant Antennas: Theory, Design and Applications (CRC Press, May 2022), and Wireless channels and radio wave propagation theory in Internet-of-Things (in Chinese, 2024). He has authored or co-authored over 200 articles published in peer-reviewed international journals and conference proceedings. He is the inventor and co-inventor of 3 USA patents and over 50 Chinese patents. He was a recipient of the Exceptional Reviewers Award of the IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION in 2016, 2020, 2021, 2022, and 2023, and the Outstanding Reviewers Award of the AEÜ: Int. J. of Electronics and Communications in 2018. He has been serving as an Editorial Board Member of the International Journal of RF and Microwave Computer-aided Engineering since 2014, an Associate Editor of the Electronics Letters since 2019, and an Editorial Board Member of the Journal of Microwaves (Wei-Bo-Xue-Bao, in Chinese) since 2023. He was titled “the New Century Excellent Talents in University” by the Ministry of Education of China (教育部新世纪优秀人才支持计划) in 2012. He received the Prize of Outstanding Young Scientists and Engineers of Chinese Institute of Communications(中国通信学会青年科技奖)in 2018. He received the Scientific and Technological Award (2nd -ranked) of the Ministry of Education of China(教育部高等学校科学研究优秀成果二等奖(技术发明类)) in 2019.
Talk Title: Fluid antennas: Practice and prototyping in a generalized odd-even mode theory framework
In this talk, the history and background of multimode resonant antennas (MRAs) are briefly introduced at first. Inspired by the analytical treatment of unbalanced currents in antenna systems, a generalized odd-even mode theory (GO-EMT) is proposed to quantitatively and approximately describe the mutual coupling effect between feed line and antenna. An elegant, closed-form formula is derived to approximately calculate the “unbalance degree” of a straight dipole off-center fed by a symmetric twin-line. It is concluded that the modal parity mismatching between the feed line and the antenna should mathematically and ultimately dominate the unbalance phenomenon in antenna systems. Next, multimode resonant antennas designed by the semi-analytical, mode synthesis approach are presented and introduced. Then, the GO-EMT is employed to reveal the mathematical essence and physical insights of fluid antennas (FAs). FA with switchable circular polarizations and its application in wireless channel sounding experiment are demonstrated to show the recent progresses in Nanjing University of Posts and Telecommunications (NUPT). As is concluded, FA having switchable circular polarizations is effective and robust in anti-fading wireless communications. GO-EMT is expected to lay down a solid foundation for high-performance, cost-effective FA developments in future wireless communications.
