Présentation

Alexandru Takacs (M’12) was born in Simleu Silvaniei, Romania, in March 1975. He received the Engineer diploma in electronic engineering from the Military Technical Academy, Bucharest, Romania, in 1999, and the Master degree and Ph.D. degree in microwave and optical communications from the National Polytechnic Institute of Toulouse (INPT), Toulouse, France, in 2000 and 2004, respectively. From 2004 to 2007, he was a Lecturer with the Military Technical Academy of Bucharest, and an Associate Researcher with the Microtechnology Institute of Bucharest. In 2008 and 2010, he occupied a Postdoctoral position with the Laboratory for Analysis and Architecture of Systems (LAAS), National Center for Scientific Research (CNRS), Toulouse, France. During 208 and 2011, he was an R&D RF Engineer with Continental Automotive SAS France, where he was in charge of antenna design and automotive electromagnetic simulation. Since 2012, he has been an Associate Professor (Habilitation à diriger des recherches HDR obtained in 2018) with the University Paul Sabatier, Toulouse, France, where he performs research within LAAS–CNRS. He has authored or coauthored two books, 39 papers in refereed journals, five international patents and over 100 communications in international symposium proceedings. His research interests include energy harvesting and wireless power transfer, battery-less wireless sensors and networks, cyber-physical systems for IoT applications, the design of microwave and RF circuits, small antenna design and flexible substrate technologies. Dr. Takacs was member of Technical Program Committee (TPC) of Wireless Power Transfer Conference WPTC’2016, WPTC’2018 and WPTC’2019 and for European Microwave Conference (EUMC’2015, EUMC’2016, EUMC’2019). He has been co-general chair of European Wireless Week (now Wireless Power Transfer Conference and Expo), co-TPC chair for European Microwave Conference (EUMC’2019) and Operational Officer and Student Grant Chair for EuMC’2015. Alex Takacs has served as guest editor for two special issues of Wireless Power Transfer Journal (Cambridge University Press).
