【主講人簡介】
Dr. Ke Wu is Professor of Electrical Engineering at Polytechnique Montreal (University of Montreal). He holds the NSERC- Huawei Industrial Research Chair in Future Wireless Technologies (the first Huawei -endowed Chair in the world). He has been the Director of the Poly- Grames Research Center. He was the Canada Research Chair (2002-2016) in RF and millimeter-wave engineering and the Founding Director (2008-2014) of the Center for Radiofrequency Electronics Research of Quebec. Dr. Wu is also with the School of Information Science and Engineering, Ningbo University, on leave from his home institution, leading a special 5G and future wireless research program. He has authored/co-authored over 1200 referred papers, and a number of books/book chapters and more than 50 patents. Dr. Wu was the general chair of the 2012 IEEE MTT-S International Microwave Symposium (the largest IEEE annual conference). He was the 2016 President of the IEEE Microwave Theory and Techniques Society (MTT-S). He also serves as the inaugural North-American representative in the General Assembly of the European Microwave Association ( EuMA ). He was the recipient of many awards and prizes including the inaugural IEEE MTT-S Outstanding Young Engineer Award, the 2004 Fessenden Medal of the IEEE Canada, the 2009 Thomas W. Eadie Medal from the Royal Society of Canada (The Academies of Arts, Humanities and Sciences of Canada), the Queen Elizabeth II Diamond Jubilee Medal, the 2013 Award of Merit of Federation of Chinese Canadian Professionals, the 2014 IEEE MTT-S Microwave Application Award, the 2014 Marie- Victorin Prize (Prix du Québec – the highest distinction of Québec in the Natural Sciences and Engineering), the 2015 Prix d’Excellence en Recherche et Innovation of Polytechnique Montréal and the 2015 IEEE Montreal Section Gold Medal of Achievement. He is a Fellow of the IEEE, a Fellow of the Canadian Academy of Engineering (CAE) and a Fellow of the Royal Society of Canada. He was an IEEE MTT-S Distinguished Microwave Lecturer from Jan. 2009 to Dec. 2011.
【講座摘要】
Tunability , controllability and reconfigurability are the most important technological enablers for the next generation smart and cognitive wireless circuits and systems for functional and efficient 5G and Internet of Things ( IoT ). This presentation reviews a set of key enabling techniques for the development of dynamically controlled circuits and systems over the MHz-to-THz frequency region. Mechanical, thermal, electrical and magnetic tuning/switching schemes and technologies are reviewed with emphasis on advanced materials-enabled design platforms such as ferroelectrics and transition compounds. In this talk, discrete and distributed design techniques are discussed with reference to a compromise between loss performance and tuning effectiveness. Simultaneous two-dimensional electric and magnetic parametric tuning and reconfigurable techniques are highlighted as the most promising and next generation design methodologies for enabling smart and wide-ranged functional control and system re-configurability. A technological outlook related to performances that can be expected from different technologies is assessed. Practical examples for tunable and reconfigurable RF and microwave circuits and systems are presented.
