Xavier Begaud

Xavier Begaud is a Professor at Telecom Paris within Institut Polytechnique de Paris, affiliated with the Communications and Electronics (Comelec) Department of the Information Processing and Communication Laboratory (LTCI). He joined Telecom Paris in 1998 and led the RF & Microwave group from 2013 to 2017, currently serving as a core member of the Radio Frequency and Microwaves (RFM²) research team. His work bridges theoretical and applied electromagnetics with strong industry collaboration.

Educational background:

• B.S. in Telecommunication, University of the South, Toulon-Var (1988)
• M.S. in Optics, Optoelectronics and Microwaves, Institut National Polytechnique de Grenoble (1989)
• Ph.D. in Electronic and Communications, University of Rennes 1 (1996)
• Habilitation in Electrical Engineering, Pierre and Marie Curie University (Paris 6) (2007)

His research centers on advanced antenna systems with emphasis on metamaterial applications. Key areas include wideband/dual-polarized antenna design, transformation optics for radiation control, and radar absorbing materials (RAM) development. Current work targets 5G/6G communication systems, UAV detection radar, and space applications requiring lightweight electromagnetic absorbers operating from GHz to millimeter waves. He employs numerical methods for modeling antennas over artificial magnetic conductors and defected ground structures.

Analysis of recent publications reveals three dominant trends: (1) Metasurface-enabled beam steering for multi-band 5G antennas, (2) Ultra-wideband metamaterial absorbers using composite materials for space/naval applications, and (3) EMF exposure reduction in mobile devices through metamaterial integration. His group consistently applies transformation optics to manipulate radiation patterns and develops multi-sector absorbers with oblique incidence tolerance.
