Until now, novices had to painstakingly dig through the literature to discover how to use Monte Carlo techniques for solving electromagnetic problems. Written by one of the foremost researchers in the field, Monte Carlo Methods for Electromagnetics provides a solid understanding of these methods and their applications in electromagnetic computation. Including much of his own work, the author brings together essential information from several different publications.Using a simple, clear writing style, the author begins with a historical background and review of electromagnetic theory. After addressing probability and statistics, he introduces the finite difference method as well as the fixed and floating random walk Monte Carlo methods. The text then applies the Exodus method to Laplace’s and Poisson’s equations and presents Monte Carlo techniques for handing Neumann problems. It also deals with whole field computation using the Markov chain, applies Monte Carlo methods to time-varying diffusion problems, and explores wave scattering due to random rough surfaces. The final chapter covers multidimensional integration.Although numerical techniques have become the standard tools for solving practical, complex electromagnetic problems, there is no book currently available that focuses exclusively on Monte Carlo techniques for electromagnetics. Alleviating this problem, this book describes Monte Carlo methods as they are used in the field of electromagnetics.

Optical and wireless technologies are being introduced into the global communications infrastructure at an astonishing pace. Both are revolutionizing the industry and will undoubtedly dominate its future, yet in the crowded curricula in most electrical engineering programs, there is no room in typical data communications courses for proper coverage of these "next generation" technologies.Optical and Wireless Communications: Next Generation Networks covers both types of networks in a unique presentation designed for a one-semester course for senior undergraduate or graduate engineering students. Part I: Optical Networks covers optical fibers, transmitters, receivers, multiplexers, amplifiers, and specific networks, including FDDI, SONET, fiber channel, and wavelength-routed networks. Part II:Wireless Networks examines fundamental concepts and specific wireless networks, such as LAN, ATM, wireless local loop, and wireless PBXs. This section also explores cellular technologies and satellite communications.Eventually, next generation networks will be as ubiquitous as traditional telephone networks, and today's engineering students must be prepared to meet the challenges of optical and wireless systems development and deployment. Filled with illustrations, examples, and end-of-chapter problems, Optical and Wireless Communications: Next Generation Networks provides a brief but comprehensive introduction to these technologies that will help future engineers build the foundation they need for success.

The demand for communication networks has increased dramatically in the last few years, creating a need for an intermediate network that operates over a metropolitan area at comparatively high data rates with simple protocols. With some characteristics of local area networks and wide area networks, the metropolitan area network (MAN) technology reflects the best features of both. The motivations for MAN technology include o interconnection of LANs o high-speed services o integrated services.MANs can be used in the following areas:LAN interconnection Filetransfer Distributed processing Remote services Remote loginMetropolitan Area Networks provides an introduction to the key concepts of MANs in an easily understood style. Organized into five chapters, this unique book acts as an excellent reference for a beginner as well as for the veteran in the field.Topics include: Introductory and background information about MANs Interworking devices, MAN topologies, and key issues Various popular protocols proposed for MANs Modeling and performance analysis of common MAN topologies Emerging MAN-related technologies such as BISDN, ATM networks, frame relay, cell relay, SONET, and SMDSFor a broad understanding of this expanding subject, Metropolitan Area Networks serves as the singular standard in the field.

This fourth edition of the text reflects the continuing increase in awareness and use of computational electromagnetics and incorporates advances and refinements made in recent years. Most notable among these are the improvements made to the standard algorithm for the finite-difference time-domain (FDTD) method and treatment of absorbing boundary conditions in FDTD, finite element, and transmission-line-matrix methods. It teaches the readers how to pose, numerically analyze, and solve EM problems, to give them the ability to expand their problem-solving skills using a variety of methods, and to prepare them for research in electromagnetism.Includes new homework problems in each chapter.Each chapter is updated with the current trends in CEM.Adds a new appendix on CEM codes, which covers commercial and free codes.Provides updated MATLAB code.

Broadband networks, such as asynchronous transfer mode (ATM), frame relay, and leased lines, allow us to easily access multimedia services (data, voice, and video) in one package. Exploring why broadband networks are important in modern-day telecommunications, Introduction to Broadband Communication Systems covers the concepts and components of both standard and emerging broadband communication network systems.After introducing the fundamental concepts of broadband communication systems, the book discusses Internet-based networks, such as intranets and extranets. It then addresses the networking technologies of X.25 and frame relay, fiber channels, a synchronous optical network (SONET), a virtual private network (VPN), an integrated service digital network (ISDN), broadband ISDN (B-ISDN), and ATM. The authors also cover access networks, including digital subscriber lines (DSL), cable modems, and passive optical networks, as well as explore wireless networks, such as wireless data services, personal communications services (PCS), and satellite communications. The book concludes with chapters on network management, network security, and network testing, fault tolerance, and analysis.With up-to-date, detailed information on the state-of-the-art technology in broadband communication systems, this resource illustrates how some networks have the potential of eventually replacing traditional dial-up Internet. Requiring only a general knowledge of communication systems theory, the text is suitable for a one- or two-semester course for advanced undergraduate and beginning graduate students in engineering as well as for short seminars on broadband communication systems.

This book covers performance analysis of computer networks, and begins by providing the necessary background in probability theory, random variables, and stochastic processes. Queuing theory and simulation are introduced as the major tools analysts have access to. It presents performance analysis on local, metropolitan, and wide area networks, as well as on wireless networks. It concludes with a brief introduction to self-similarity. Designed for a one-semester course for senior-year undergraduates and graduate engineering students, it may also serve as a fingertip reference for engineers developing communication networks, managers involved in systems planning, and researchers and instructors of computer communication networks.
