Substrate Integrated Suspended Line Circuits and Systems by Kaixue Ma,Yongqiang Wang Pdf

Substrate Integrated Suspended Line Circuits and Systems provides a systematic overview of the new transmission line - the substrate-integrated suspension line (SISL). It details the fundamentals and classical application examples of the SISL. The basic SISL concept and structure, various passive circuits and active circuits, and front-end sub-systems are systematically introduced. Featuring research on topics such as high-performance RF/microwave/mm-wave circuits and system, this book is ideal for researchers, engineers, scientists, scholars, educators, and students. Since transmission line is a fundamental component of microwave and mm-wave circuits, the properties of a transmission line, such as losses, size, and dispersion, are vital to the performance of the whole system. Suspended line has been proved to be an excellent transmission line, as it has attractive features such as low loss, weak dispersion, high power capacity, and low effective dielectric constant. However, Conventional waveguide suspended line circuits require metal housing to form air cavities which is Substrate Integrated Suspended Line Circuits and Systems essential to the operation of suspended lines circuits. Also, the metal shell should provide mechanical support and shielding, which contribute to large size and heavy weight. Meanwhile, precise mechanical fabrication and assembling are strongly required, which brings difficulties to the design and fabrication of conventional suspended line circuits, and the manufacturing cost of suspended line circuits increases correspondingly. In this book, we will introduce a new platform of high-performance transmission line, i.e. substrate integrated suspended line (SISL). SISL keeps all the merits of the suspended line while overcomes the drawbacks of conventional waveguide suspended line circuits. Moreover, it is self-packaged and highly integrated. The basic SISL concept and structure, various passive circuits and active circuits, and front-end sub-systems will be systematically introduced. Featuring research on topics such as high-performance RF/microwave/mm-wave circuits and system, this book is ideally designed for researchers, engineers, scientists, scholars, educators, and students.

Nonlinear Design: FETs and HEMTs by Peter H. Ladbrooke Pdf

Despite its continuing popularity, the so-called standard circuit model of compound semiconductor field-effect transistors (FETs) and high electron mobility transistors (HEMTs) is shown to have a limitation for nonlinear analysis and design: it is valid only in the static limit. When the voltages and currents are time-varying, as they must be for these devices to have any practical use, the model progressively fails for higher specification circuits. This book shows how to reform the standard model to render it fully compliant with the way FETs and HEMTs actually function, thus rendering it valid dynamically. Proof-of-principle is demonstrated for several practical circuits, including a frequency doubler and amplifiers with demanding performance criteria. Methods for extracting both the reformulated model and the standard model are described, including a scheme for re-constructing from S-parameters the bias-dependent dynamic (or RF) I(V) characteristics along which devices work in real-world applications, and as needed for the design of nonlinear circuits using harmonic-balance and time-domain simulators. The book includes a historical review of how variations on the standard model theme evolved, leading up to one of the most widely used—the Angelov (or Chalmers) model.

Electromagnetic and Photonic Simulation for the Beginner: Finite-Difference Frequency-Domain in MATLAB® by Raymond C. Rumpf Pdf

This book teaches the finite-difference frequency-domain (FDFD) method from the simplest concepts to advanced three-dimensional simulations. It uses plain language and high-quality graphics to help the complete beginner grasp all the concepts quickly and visually. This single resource includes everything needed to simulate a wide variety of different electromagnetic and photonic devices. The book is filled with helpful guidance and computational wisdom that will help the reader easily simulate their own devices and more easily learn and implement other methods in computational electromagnetics. Special techniques in MATLAB® are presented that will allow the reader to write their own FDFD programs. Key concepts in electromagnetics are reviewed so the reader can fully understand the calculations happening in FDFD. A powerful method for implementing the finite-difference method is taught that will enable the reader to solve entirely new differential equations and sets of differential equations in mere minutes. Separate chapters are included that describe how Maxwell’s equations are approximated using finite-differences and how outgoing waves can be absorbed using a perfectly matched layer absorbing boundary. With this background, a chapter describes how to calculate guided modes in waveguides and transmission lines. The effective index method is taught as way to model many three-dimensional devices in just two-dimensions. Another chapter describes how to calculate photonic band diagrams and isofrequency contours to quickly estimate the properties of periodic structures like photonic crystals. Next, a chapter presents how to analyze diffraction gratings and calculate the power coupled into each diffraction order. This book shows that many devices can be simulated in the context of a diffraction grating including guided-mode resonance filters, photonic crystals, polarizers, metamaterials, frequency selective surfaces, and metasurfaces. Plane wave sources, Gaussian beam sources, and guided-mode sources are all described in detail, allowing devices to be simulated in multiple ways. An optical integrated circuit is simulated using the effective index method to build a two-dimensional model of the 3D device and then launch a guided-mode source into the circuit. A chapter is included to describe how the code can be modified to easily perform parameter sweeps, such as plotting reflection and transmission as a function of frequency, wavelength, angle of incidence, or a dimension of the device. The last chapter is advanced and teaches FDFD for three-dimensional devices composed of anisotropic materials. It includes simulations of a crossed grating, a doubly-periodic guided-mode resonance filter, a frequency selective surface, and an invisibility cloak. The chapter also includes a parameter retrieval from a left-handed metamaterial. The book includes all the MATLAB codes and detailed explanations of all programs. This will allow the reader to easily modify the codes to simulate their own ideas and devices. The author has created a website where the MATLAB codes can be downloaded, errata can be seen, and other learning resources can be accessed. This is an ideal book for both an undergraduate elective course as well as a graduate course in computational electromagnetics because it covers the background material so well and includes examples of many different types of devices that will be of interest to a very wide audience.

Networking Infrastructure for Pervasive Computing by Debashis Saha,Amitava Mukherjee,Somprakash Bandyopadhyay Pdf

The authors (two of whom are from the Indian Institute of Management Calcutta, India) argue that the possibilities of "Pervasive Computing" promises to extend the information-networked environment to practically every technological device, but that the current networking and communication infrastructure doesn't support those possibilities. Largely concerning themselves with networking technologies, they provide advice on the problems of addressing this gap between promise and infrastructure.

Mobile Information Systems by Elaine Lawrence,Barbara Pernici,John Krogstie Pdf

Mobility is perhaps the most important market and technological trend within information and communication technology. With the advent of new mobile infrastructures providing higher bandwidth and constant connection to the network from virtually everywhere, the way people use information resources is predicted to be radically transformed. Over the last years, a new breed of information systems, referred to as mCommerce systems or mobile information systems, has appeared to address this emerging situation. In 2000, the IFIP 8.1 WG decided to look into establishing a task group to look closer at this area, and the idea was adopted and extended by IFIP TC8 the following year. After the arrangement of several workshop, this task group has been the driving force behind the arrangement of MOBIS (IFIP TC 8 Working Conference on Mobile Information systems) held in Oslo, Norway, 15-17 September 2004. The objective of the working conference was to provide a forum for researchers and practitioners interested in planning, analysis, design, construction, modification, implementation, utilization, evaluation, and management of mobile information systems to meet, and exchange research ideas and results. Specifically, we tried to use the working conference to • Clarify differences and similarities between the development of mobile vs. more traditional information systems • Investigate organizational impact of mobile information systems • Investigate mobile commerce applications combined with the advantages of mobile communications technologies X Mobile Information Systems • Evaluate existing and newly developed approaches for analysis, design, implementation, and evolution of mobile information systems.
