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 techniquesEach 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.

Fashion and beauty have helped shape history and today more than ever, we find ourselves under increasing pressure to think about what we wear, what we look good in and how best to enhance our body shape and size. Behind this seemingly superficial industry, however, lies a technical thinking firmly grounded in science and technology. In one fully comprehensive book, Clothing appearance and fit: Science and technology provides a critical appreciation of the technological developments and scientific understanding of the appearance and fit of clothing. The authors bridge the science of beauty and fashion design with garment evaluation technology, garment drape and human anthropometrics and sizing.The ten chapters of the book provide a detailed coverage of clothing appearance and fit. Chapter 1 considers body attractiveness and how it relates to clothing material and design parameters and discusses classical and contemporary theories of beauty. Chapters 2 and 3 present the industry''s techniques, methods and standards for assessing clothing appearance and fit and Chapters 4 and 5 review the research and development of objective measurement technologies for evaluating clothing appearance and fit. Fabric objective measurement, fabric properties and garment drape are covered in Chapters 6 and 7 and the R & D of body measurement, anthropometrics and sizing systems are detailed in Chapters 8 and 9. The final chapter reviews published work on garment design and pattern alteration for achieving good clothing appearance and fit.This book is an essential reference for researchers, academics, professionals and students in clothing and textile academia and industry. It includes many industrial standards, techniques and practices.- Offers a critical appreciation of technological developments- Incorporates user-friendly illustrations and photographs- Valuable reference for students, researchers and professionals in the clothing and textile industries
