  • Simple Propagation Models and Ray Solutions

    The topic of electromagnetic (EM) wave propagation through complex environments has been and will continue to be of great interest for communication and radar systems. Simple propagation models are introduced in this chapter. First, a simple ray-shooting MATLAB package is designed and discussed. The package may be used as an educational tool in various EM lectures (e.g., EM wave theory, antennas and propagation, wireless propagation, etc.) as well as a research tool to predict ducting and/or antiducting conditions in the presence of buildings and under various atmospheric refractivity conditions. Then, early analytical ray-based models are discussed. Propagation over nonpenetrable flat earth with the simple two ray (2Ray) model and single knife-edge problem with the four ray (4Ray) model are summarized with basic examples and illustrations.

  • Optical Layer

    Enables engineers to better understand, implement, and comply with G-PON standards A passive optical network (PON) is a point-to-multipoint, fiber-to-the- premises network architecture in which unpowered optical splitters enable a single optical fiber to serve multiple premises. PONs consist of an optical line terminal at the service provider's central office and a number of optical network units near the end users. Compared with point-to-point architectures, PONs reduce the amount of fiber and central office equipment required. Gigabit-capable PONs (G-PONs) are today's access network sweet spot, optimized to deliver IPTV and other high-bandwidth services at a reasonable cost. G-PONs have been deployed in numerous networks across the globe, and the trends indicate higher growth for G-PONs than other PON technologies. Written by experts at the heart of G-PON development, standardization, and deployment, this text explains why the G-PON standards are what they a e and how they impact the development of communication networks. It fully examines the historical development of the G-PON standards, pointing out alternatives and comparing them to other PON standards. The book begins with an introduction to the evolution of G-PON technology and standards. Next, it covers: * System requirements * Optical layer * Transmission convergence layer * Management * Services * Other technologies such as Ethernet PON, wireless broadband, and access migration This book not only examines current standards and technology, it also looks at evolving technology, discussing the advantages and disadvantages of various access networks currently under investigation. Gigabit-capable Passive Optical Networks is essential for all engineers responsible for developing and maintaining G-PONs, providing them with information and guidance they need to ully understand, implement, and comply with the standards.

  • Geometrical Optics

    Geometrical Optics uses the concept of rays, which have direction and position but no phase information, to model the way light travels through space or an optical system. This chapter focuses on imaging systems, which cover a broad class of engineering applications. It assumes that an object is viewed as a collection of many pinpoint sources of light and that some of them will be captured by the imaging system. Those captured ray sources will be traced through an optical system to determine what image will be formed. This technique is useful for designing lenses, developing systems of lenses for use in microscopes, telescopes, cameras, and other devices. The chapter talks about the cardinal points of an optical system, which are the first and second focal points, principal points, and nodal points. It describes the various stops and apertures that characterize the imaging performance of an optical system.

  • Petool Virtual Propagation Package

    This chapter introduces a novel software tool (PETOOL), which is developed in MATLAB with graphical user interface (GUI) for the analysis and visualization of radio wave propagation through the homogeneous and inhomogeneous atmosphere, by incorporating variable terrain effects with the aid of the two‐way split‐step algorithm employing wide‐angle propagator. The PE method handles only the forward‐propagating waves and neglects the backscattered waves. The forward waves provide almost accurate results for typical long‐range propagation problems, only if there does not exist obstacles that redirect the incoming wave in the form of reflections and diffractions. PETOOL software package has been developed in MATLAB with a user‐friendly GUI for the analysis and visualization of radio wave propagation. The user should be able to easily specify range dependent or range independent refractivity profiles by just selecting from a list of various types of atmosphere profiles.

In addition, the book presents up-to-date systems and methods to illustrate how these applications work in practice. This includes systems working in the HF bands and SHF. Furthermore, the author examines the performance of these systems, and also the effects of noise, interference and deliberate jamming, as well as the performance of jamming, detection and intercept systems. Particular attention is paid to the problems caused by Radio Controlled Improvised Explosive Devices (RCIEDs). **Key Features:** * * Written by an expert in both the civilian and military applications of the technology * Focuses on methods such as radio and radar jamming, and radio-controlled improvised explosive devices (IEDs) * Contains problems and solutions to clarify key topics

  • Propagation Effects Modeling and Prediction

    This chapter provides descriptions of prediction models and procedures used for the evaluation of atmospheric propagation degradation on satellite links. It is organized into sections for each of the major weather effects, including atmospheric gaseous attenuation, cloud and fog attenuation, rain attenuation, rain and ice depolarization and scintillation. Two excellent sources are available to provide predictions of attenuation due to gaseous absorption. They are the Liebe Complex Refractivity Model, and procedures developed by the ITU‐R. The ITU‐R provides two procedures for gaseous attenuation prediction: a detailed line‐by‐line summation of the spectral lines of water vapor and oxygen, similar to the Liebe method and, a simpler approximation to the line‐by line approach. The chapter presents two rain attenuation models that have performed well for many diverse regions and types of rain, the ITU‐R rain attenuation model, and the Crane global model.
