Master powerful new modeling tools that let you quantify and represent metamaterial properties with never-before accuracy. This first-of-its-kind book brings you up to speed on breakthrough finite-difference time-domain techniques for modeling metamaterial characteristics and behaviors in electromagnetic systems. This practical resource comes complete with sample FDTD scripts to help you pave the way to new metamaterial applications and advances in antenna, microwave, and optics engineering. You get in-depth coverage of state-of-the-art FDTD modeling techniques and applications for electromagnetic bandgap (EBG) structures, left-handed metamaterials (LHMs), wire medium, metamaterials for optics, and other practical metamaterials. You find steps for computing dispersion diagrams, dealing with material dispersion properties, and verifying the left-handedness. Moreover, this comprehensive volume offers guidance for handling the unique properties possessed by metamaterials, including how to define material parameters, characterize the interface of metamaterial slabs, and quantify their spatial as well as frequency dispersion characteristics. The book also presents conformal and dispersive FDTD modeling of electromagnetic cloaks, perfect lens, and plasmonic waveguides, as well as other novel antenna, microwave, and optical applications. Over 190 illustrations support key topics throughout the book.

  • Yang Hao Yang Hao is Professor of Antennas and Electromagnetics at Queen Mary University of London (QMUL). Over the years, he has developed several fully-integrated antenna solutions based on novel artificial materials to reduce mutual RF interference, weight, cost and system complexity for security, aerospace and healthcare applications. He coined the term 'Body-centric wireless communications', an area which refers to networking among wearable and implantable wireless sensors on the human body. He contributed to the industrial development of wireless sensors for healthcare monitoring as well as wearable and textile antennas. He currently leads several major developments in microwave metamaterials, body-centric wireless communications and is also a member of management team at the Cambridge Graphene Centre. Professor Hao has published 2 books, 7 book chapters and more than 120 journal papers. From 2010-2012, he served as a Vice Chairman for the Professional Network on Antenna and Propagations, IET and is also a board member of European School of Antennas, European Antenna Centre of Excellence. He is an associate editor for both IEEE TAP and AWPL. In 2013, Professor Hao received the prestigious Wolfson Research Merit Award from the Royal Society, UK. He is a Fellow of IEEE, IET and ERA Foundation.
