Autorenporträt

Xavier Begaud is Associate Professor at TELECOM ParisTech in France. His main research interests are the theory, conception, modeling and characterization of wideband, dual polarized and 3D antennas (with special emphasis on numerical methods), and the design of metamaterials, channel sounders and mutual coupling analysis in the framework of UltraWideBand and Software Radio.
