Analytical Methodology of Tree Microstrip Interconnects Modelling For Signal Distribution

Dr. Blaise Ravelo is currently an Associate Professor at the Graduate Engineering School, ESIGELEC located in Rouen, France. His research interest is focused on:- the design of RF/microwave circuits for wireless communication system, - development and applications of negative group delay (NGD) circuits, - the electrical RF/mixed circuit interconnect modelling for signal and power integrity (SI/PI) analysis, - EM near-field scanning and modelling, electromagnetic compatibility/interference (EMC/EMI), and Multiphysics system engineering/modelling. He is a pioneer of the development of NGD concept. Dr. Ravelo received the Dipl.-Ing. Degree in electronic engineering from the University of Antsiranana, Madagascar, in 2000. He received the Professional/Research Sci. Master degrees, and the Ph.D. degrees from Brest University, Brest, France, in 2004, 2005, and 2008, respectively. He hold his degree of dissertation to lead researches (“HDR: Habilitation à Diriger des Recherches”) from the Univ. of Rouen in 2012. Dr. Ravelo is regularly involved and initiated to participate and to lead national and international research projects (FP7, INTERREG, ANR, FUI, H2020, Euripides, Eurostars) on the electronic, microwave and EMC engineering. He is (co)author of more than 210 papers published in international journals, book chapters, and conference proceedings. He co-supervised and directed 9 PhD students whose 6 PhD candidates defended.
