Biography

Dr. Sergiu Iordanescu graduated the Faculty of Electronics and Telecommunications at the Polytechnic Institute of Bucharest, Romania, in 1972 and received the Ph.D. degree in electronic engineering from the University “Politehnica” Bucharest, Romania, in 2000.
From 1972 to 1977, he was with the Institute of Physics and Technology of Radiation Apparatus, Romania. He was Research Scientist with the National Institute for R&D in Microtechnologies (IMT), Romania from 1977 to 2000 and Senior Engineer with Alvarion Romania SRL from 2000 to 2015. Since 2015, he is Senior Researcher with the National Institute for R&D in Microtechnologies (IMT), Bucharest, Romania. Dr. Iordanescu is the author of more than 80 scientific papers in peer-reviewed journals and conferences. His research interests include microwave SAW filter and sensor design and characterisation, dielectric and ferroelectric materials characterisation as well as the design of various microwave and millimetre wave circuits. He received the “Tudor Tanasescu” Romanian Academy award (with team) for the study “Micromachined circuits for microwave and millimeter wave applications – MEMSWAVE”, in 2003. He is member of IEEE since 1991.
