Ass. Professor (Sorbonne-Université)

email : julien.sarrazin [at] sorbonne-universite.fr


He received in 2005 the M.S. degree in telecommunication and electrical engineering from the University of Nantes in France, the Master of Engineering from Polytech'Nantes, and in 2008, the Ph.D. degree in electronics and telecommunication from the University of Nantes. He then worked at the BK Birla Institute of Technology (BKBIET) of Pilani, India, in 2009 and 2010.

From 2005 to 2010, he conducted his research on collocated and reconfigurable microwave antennas for Multiple Input Multiple Output (MIMO) systems.

In 2011, he joined the Radio Frequency and Microwave group at Telecom ParisTech, in Paris, as a research engineer. There he worked on metamaterials for antennas, with a focus on high-impedance surfaces. He also developed new designs of antennas absorbers for space applications.

Since September 2012, he is an associate professor at Sorbonne Université in Paris, where he joined the Laboratory of Electronics and Electromagnetism (L2E) and later the Group of Electrical Engineering of Paris (GeePs) to conduct his research. Since then, he has (co)-supervised 15 PhD students. He received his HDR (French accreditation to supervise research) in 2018. During 2013-2019, he oversaw the P-SYS scientific theme at L2E, which dealt with connected systems in the vicinity of people. Since 2020, he is the head of the wave & propagation team (19 Prof. & ass. Prof.) at GeePs. Since 2019, he is the vice-chair of the URSI-France B-commission. He was a visiting faculty at IIT Bombay, India, from January to June 2020.

He teaches at both Bachelor and Master levels, where he is the responsible of the courses of Waveguide Theory, Transmission Line Theory, and Wireless Communications. He is co-responsible of the Master programs in communicating systems at Sorbonne University, namely the SysCom program and the international M2 WaveWiCom program.

He has been the coordinator of several collaborative projects including GEOHYPE (ANR JCJC), SMART-BAN (SMART LabEx), and NOVIS60 (CEFIPRA Indo-French center). He is currently leading the ANR-funded project BeSensiCom and is involved in the EU-funded Doctoral Network GENIUS and the ANR-funded MOCACCINO project. He is a managing committee member for France in the EU INTERACT COST Action and serves as Associate Editor for IEEE Access since 2022.

His field of scientific expertise is related to “Antennas and Propagation” with part of his activities oriented towards electromagnetics (e.g., radiating structure design, propagation channel modeling) and another part oriented towards communications (e.g., localization and focalization of data using multiple antenna systems).

His research topics include:

· Angle-of-Arrival estimation in millimeter-wave propagation channels

· Spatial Data Focusing and Physical Layer Security

· Localization in the sub-6 GHz and millimeter-wave band

· Body Area Networks

· High Impedance Surfaces for antennas and electromagnetic absorbers

· Antenna Design for MIMO Systems
