Electromagnetic Waves and Antennas - Sophocles J. Orfanidis

This book provides a broad and applications-oriented introduction to electromagnetic waves and antennas. Current interest in these areas is driven by the growth in wireless and fiber-optic communications, information technology, and materials science.

Communications, antenna, radar, and microwave engineers must deal with the generation, transmission, and reception of electromagnetic waves. Device engineers working on ever-smaller integrated circuits and at ever higher frequencies must take into account wave propagation effects at the chip and circuit-board levels. Communication and computer network engineers routinely use waveguiding systems, such as transmission lines and optical fibers. Novel recent developments in materials, such as photonic bandgap structures, omnidirectional dielectric mirrors, birefringent multilayer films, surface plasmons, negative-index metamaterials, slow and fast light, promise a revolution in the control and manipulation of light and other applications. These are just some examples of topics discussed in this book.

The book is organized around three main topic areas:

• The propagation, reflection, and transmission of plane waves, and the analysis and design of multilayer films.
• Waveguides, transmission lines, impedance matching, and S-parameters.
• Linear and aperture antennas, scalar and vector diffraction theory, antenna array design, and coupled antennas.

Well Played 1.0: Video Games, Value and Meaning

Video games can be “well played” in two senses. On the one hand, well played is to games as well read is to books. On the other hand, well played as in well done. This book is full of in-depth close readings of video games that parse out the various meanings to be found in the experience of playing a game. 22 contributors (developers, scholars, reviewers and bloggers) look at video games through both senses of “well played.” The goal is to help develop and define a literacy of games as well as a sense of their value as an experience. Video games are a complex medium that merits careful interpretation and insightful analysis.

Debugging C and C++ code in a Unix environment

Debugging is the art of removing bugs from software. The software may be code, documentation, or any other intellectual product. Here, we will look at the debugging of computer programs (or libraries) written in C or C⁺⁺ in a Unix environment. Most of it is also applicable to other compiled procedural and object oriented languages like Pascal, Modula and Objective C.

Book: Fundamentals of Wireless Communication

The past decade has seen many advances in physical-layer wireless communication theory and their implementation in wireless systems. This textbook takes a unified view of the fundamentals of wireless communication and explains the web of concepts underpinning these advances at a level accessible to an audience with a basic background in probability and digital communication. Topics covered include MIMO (multiple input multiple output) communication, space-time coding, opportunistic communication, OFDM and CDMA. The concepts are illustrated using many examples from wireless systems such as GSM, IS-95 (CDMA), IS-856(1xEV-DO), Flash OFDM and ArrayComm SDMA systems. Particular emphasis is placed on the interplay between concepts and their implementation in systems. An abundant supply of exercises and figures reinforce the material in the text. This book is intended for use on graduate courses in electrical and computer engineering and will also be of great interest to practicing engineers.

Digital Circuits

Analog signals have a continuous range of values within some specified limits and can be associated with continuous physical phenomena.
Digital signals typically assume only two discrete values (states) and are appropriate for any phenomena involving counting or integer numbers.

While we were mostly interested in voltages and currents at specific points in analog circuits, we will be interested in the information flow in digital circuits.

The active elements in digital circuits are either bipolar transistors or FETs. These transistors are permitted to operate in only two states, which normally correspond to two output voltages. Hence the transistors act as switches.
