Get ready for the tidal wave of "body centric" electronic systems that will take mobile communications and computing to new heights! Now in a newly updated and revised edition, this timely resource provides you with complete and current details on the theory, design, and applications of wireless antennas for on-body electronic systems. The Second Edition offers readers brand new material on important developments like advances in physical phantom design and production, simulation methods and numerical phantoms, descriptions of methods for simulation of moving bodies, and the use of the body as a transmission channel. This cutting-edge volume brings practitioners the state-of-the-art in existing applications like Bluetooth headsets together with detailed treatment of techniques, tools, and challenges in developing on-body antennas for an array of medical, emergency response, law enforcement, personal entertainment, and military applications on the horizon. It covers on-body communication channels at microwave frequency and low frequency bands, as well as ultra wideband systems for WPANs and WBANs. This volume is indispensable to all engineers involved in designing, testing, and improving body-centric communication systems.

Artificial metamaterials have made a huge splash in antenna, microwave, and optics engineering thanks to their extraordinary electromagnetic properties. And now, modeling their unique characteristics and behaviors in electromagnetic systems just got easier. This one-stop resource gives engineers powerful finite-difference time-domain (FDTD) techniques for modeling metamaterials, complete with applications and time-saving sample FDTD scripts. This comprehensive volume provides how-to guidance in a wide range of areas that are critical to antenna design, from computing dispersion diagrams and verifying left-handedness...to characterizing the interface of metamaterial slabs. The book also reviews electromagnetic metamaterial basics and FDTD essentials, providing the foundation needed to fully understand the material.
