Design methodology to enhance high impedance surfaces performances
Main Article Content
Abstract
A methodology is introduced for designing wideband, compact and ultra-thin high impedance surfaces (HIS). A parametric study is carried out to examine the effect of the periodicity on the electromagnetic properties of an HIS. This approach allows designers to reach the best trade-off for HIS performances.

X. Begaud, Telecom ParisTech
Xavier Begaud was born on December 11, 1968 in Chateaudun, France. He received a M.S. degree in optics, optoelectronics and microwaves, from Institut National Polytechnique de Grenoble (INPG) in 1992. He received the Ph.D. degree from the University of Rennes in 1996 and the habitation degree from Pierre and Marie Curie University (Paris 6) in 2007. He joined the Télécom ParisTech (formerly Ecole Nationale des Telecommunications) in 1998, where he is presently professor at communications and electronics Department. He works with the Radiofrequency and Microwave Group of CNRS, the French National Scientific Research Center. His research topics include theory, conception, modeling, and characterization of wideband, bipolarized and 3D antennas with special emphasis on numerical methods. Currently, research activities include design of metamaterials, channel sounding, and mutual coupling analysis in the framework of ultra-wideband and software radio. He has published over 120 journal papers, patents, book chapters, and conference articles. He has organized two international conferences as the general chairman and edited 1 book.
