Transformation Optics-based Antennas is organized into two chapters that follow an introduction that presents the basic principles of the transformation optics concept. Two types of transformation are presented, coordinate transformation and space transformation. Implementations using metamaterials are also discussed. Chapter One focuses on coordinate transformation in the design of devices capable of modifying the electromagnetic appearance of a radiating source. Transformation of a directive radiation pattern into an isotropic one (and vice-versa) through space stretching and compression, respectively, and the possibility of creating multiple beams are also studied. Chapter Two deals with devices designed using space transformation concepts. Quasi-conformal transformation optics (QCTO) are applied for the design of lenses, either to compensate for the phase shift created by the conformation of an array of sources or to steer a beam to an off-normal direction. - Focuses firstly on the theoretical tools that define transformation optics - Address the origin of these concepts by analyzing Fermat's principle - Details the basic approaches and methods needed to design practical applications of transformation optics concepts
Nawaz received the Ph.D. degree from the University of Nantes (FR) in 2005. His Ph.D. research works dealt with the applications of split ring resonators (SRRs) to microwave devices and antennas. He is an Associate Professor at the University of Paris Ouest and carries his research activities at the IEF. His current research interests are in the areas of microwave and applications of periodic structures, complex media, metamaterials and metasurfaces, in the analysis of integrated planar and conformal circuits and antennas. He is also involved in the design of microwaves devices based on the powerful concept of transformation optics. He has published more than 50 papers in scientific journals and holds 1 patent on a metamaterial-based antenna. Dr. Burokur has been the recipient of the Young Scientist Award, presented by the Union Radio-Scientifique Internationale (URSI) Commission B, in 2005.
