The recent shift in focus from defense and government work to commercial wireless efforts has caused the job of the typical microwave engineer to change dramatically. The modern microwave and RF engineer is expected to know customer expectations, market trends, manufacturing technologies, and factory models to a degree that is unprecedented in the

This volume, RF and Microwave Applications and Systems, includes a wide range of articles that discuss RF and microwave systems used for communication and radar and heating applications. Commercial, avionics, medical, and military applications are addressed. An overview of commercial communications systems is provided. Past, current, and emerging cellular systems, navigation systems, and satellite-based systems are discussed. Specific voice and data commercial systems are investigated more thoroughly in individual chapters that follow. Detailed discussions of military electronics, avionics, and radar (both military and automotive) are provided in separate chapters. A chapter focusing on FR/microwave energy used for therapeutic medicine is also provided. Systems considerations including thermal, mechanical, reliability, power management, and safety are discussed in separate chapters. Engineering processes are also explored in articles about corporate initiatives, cost modeling, and design reviews. The book closes with a discussion of the underlying physics of electromagnetic propagation and interference. In addition to new chapters on WiMAX and broadband cable, nearly every existing chapter features extensive updates and several were completely rewritten to reflect the massive changes areas such as radio navigation and electronic warfare.

A Pew Study reports that only 2% of America's twelve million bloggers claim "religion, spirituality or faith" as their main topic. This leaves a great mission field in cyberspace, say contributors to The New Media Frontier, because the latest forms of communication present so many opportunities to promote the cause of Christ in other topics and fields. Before blindly jumping in, however, Christians need to weigh the possibilities against the consequences, and then proceed with the practical discernment and grace this book provides. With a foreword by national radio host Hugh Hewitt-who has been at the forefront of the new media movement among Christians-editors Roger Overton and John Mark Reynolds (along with an impressive list of other new media experts) survey the current landscape and explore specific areas in which God's people can creatively expand their reach to a lost world. By stressing the urgency for Christian involvement, unearthing the dangers, and advising readers on how to use this media with different audiences, this book equips believers to advance, demonstrate, and utilize the Christian worldview in this exciting realm.

This book systematically introduces electromagnetic theories and their applications in practice: electrostatic energy, Poynting theorem, the polarization of waves, the conservation law, the electromagnetic symmetry, the conformal mapping method, the electromagnetic loss. The parameters and theorems of electromagnetic theories are discussed in detail, making the book an essential reference for researchers, and engineers in electromagnetics field.
