Book Description
Up-to-date coverage of the analysis and applications of coplanar waveguides to microwave circuits and antennas The unique feature of coplanar waveguides, as opposed to more conventional waveguides, is their uniplanar construction, in which all of the conductors are aligned on the same side of the substrate. This feature simplifies manufacturing and allows faster and less expensive characterization using on-wafer techniques. Coplanar Waveguide Circuits, Components, and Systems is an engineer's complete resource, collecting all of the available data on the subject. Rainee Simons thoroughly discusses propagation parameters for conventional coplanar waveguides and includes valuable details such as the derivation of the fundamental equations, physical explanations, and numerical examples. Coverage also includes: Discontinuities and circuit elements Transitions to other transmission media Directional couplers, hybrids, and magic T Microelectromechanical systems based switches and phase shifters Tunable devices using ferroelectric materials Photonic bandgap structures Printed circuit antennas

Book Description
Bridges the gap between FDTD theory and the implementation of practical simulation techniques This is the first publication that guides readers step by step through the implementation of electromagnetic simulation techniques based on FDTD methods. These simulation techniques serve as an essential bridge between FDTD methods and their applications. Moreover, the book helps readers better understand the underlying logic of FDTD methods so that they can design FDTD projects using either commercial electromagnetic software packages or their own codes in order to solve practical engineering problems. The book begins with two chapters that introduce the basic concepts of the 3-D Cartesian FDTD method, followed by discussions of advanced FDTD methods such as conformal techniques, dispersive media, circuit elements, and near-to-far field transformation. Next, the book: Presents basic concepts of parallel processing techniques and systems, including parallel FDTD techniques and systems Explores simulation techniques based on FDTD methods Illustrates practical simulation techniques using engineering applications Introduces advanced simulation techniques Each chapter concludes with references to help readers investigate particular topics in greater depth. Each chapter also includes problem sets that challenge readers to put their new FDTD and simulation skills into practice. By bridging the gap between FDTD theory and practical simulation techniques, this publication is an invaluable guide for students and engineers who need to solve a wide range of design problems in RF, antenna, and microwave engineering.

Book Description
A major update of solar cell technology and the solar marketplace Since the first publication of this important volume over a decade ago, dramatic changes have taken place with the solar market growing almost 100-fold and the U.S. moving from first to fourth place in the world market as analyzed in this Second Edition. Three bold new opportunities are identified for any countries wanting to improve market position. The first is combining pin solar cells with 3X concentration to achieve economic competitiveness near term. The second is charging battery-powered cars with solar cell generated electricity from arrays in surrounding areas including the car owners' homes while simultaneously reducing their home electricity bills by over ninety percent. The third is formation of economic "unions" of sufficient combined economic size to be major competitors. In this updated edition, feed-in tariffs are identified as the most effective approach for public policy. Reasons are provided to explain why pin solar cells outperform more traditional pn solar cells. Field test data are reported for nineteen percent pin solar cells and for ~500X concentrating systems with bare cell efficiencies approaching forty percent. Paths to bare cell efficiencies over fifty percent are described, and key missing program elements are identified. Since government support is needed for new technology prototype integration and qualification testing before manufacturing scale up, the key economic measure is identified in this volume as the electricity cost in cents per kilowatt-hour at the complete installed system level, rather than just the up-front solar cell modules' costs in dollars per watt. This Second Edition will benefit technologists in the fields of solar cells and systems; solar cell researchers; power systems designers; academics studying microelectronics, semiconductors, and solar cells; business students and investors with a technical focus; and government and political officials developing public policy.

Book Description
The first complete guide to nonlinear theory and practice for engineers Nonlinear Optics is a highly accessible, applications-oriented introduction to a new and rapidly growing field. An indispensable resource for both electrical engineering students and professionals working in the telecommunications and optoelectronics industry, it: * Treats the subject of nonlinear optics in purely classical terms for electrical engineers * Offers numerous real-world examples clearly demonstrating the connection between theory and practical application * Features helpful chapter-end problems and numerous examples * Explores current and future applications of nonlinear optics in telecommunications, computers, and other fields Due to its many applications in fiber-optic communications and optoelectronics the propagation of light through nonlinear media is an increasingly important topic among electrical engineers. Unfortunately, books geared to the specific concerns of electrical engineering students and professionals in the telecommunications and optoelectronics industry continue to be in short supply. This book is designed to fill that gap. Nonlinear Optics is a complete, self-contained, applications-oriented introduction to the field. In an effort to make this book as accessible as possible to its intended audience, E. G. Sauter has foregone quantum mechanical descriptions, choosing instead to treat the subject of nonlinear optics in purely classical terms. He has also included numerous real-world examples that clearly demonstrate the connection between theory and practical application. The book begins with the theoretical foundations for the practical discussions that follow. Dr. Sauter treats the basic relations between polarization and electric field strength, the different nonlinear effects of polarizations of order two and three, wave propagation of complex phasors in nonlinear media and anisotropic media, and the conservation of energy and momentum in nonlinear processes. Over the six chapters that follow, these theories are applied to specific cases, including the linear electrooptic effects; second harmonic generation; parametric effects; four-wave mixing, including the Raman and Brillouin effects; and the optical Kerr effect. The remaining chapters present in-depth discussions of pulse propagation, solitons, and nonlinear effects in glass fibers. Helpful problems appear at the end of each chapter, and numerous worked and unworked examples are scattered throughout the text to elucidate principles and clarify complex material. A highly accessible, applications-oriented introduction to a new and rapidly growing field, Nonlinear Optics is an indispensable resource for both electrical engineering students and working professionals.

Book Description
The first edition of “Microstrip Filters for RF/Microwave Applications” was published in 2001. Over the years the book has been well received and is used extensively in both academia and industry by microwave researchers and engineers. From its inception as a manuscript the book is almost 8 years old. While the fundamentals of filter circuits have not changed, further innovations in filter realizations and other applications have occurred with changes in the technology and use of new fabrication processes, such as the recent advances in RF MEMS and ferroelectric films for tunable filters; the use of liquid crystal polymer (LCP) substrates for multilayer circuits, as well as the new filters for dual-band, multi-band and ultra wideband (UWB) applications. Although the microstrip filter remains as the main transmission line medium for these new developments, there has been a new trend of using combined planar transmission line structures such as co-planar waveguide (CPW) and slotted ground structures for novel physical implementations beyond the single layer in order to achieve filter miniaturization and better performance. Also, over the years, practitioners have suggested topics that should be added for completeness, or deleted in some cases, as they were not very useful in practice. In view of the above, the authors are proposing a revised version of the “Microstrip Filters for RF/Microwave Applications” text and a slightly changed book title of “Planar Filters for RF/Microwave Applications” to reflect the aforementioned trends in the revised book.
