Chapter 12. Multimode Communications Using Orbital Angular Momentum

By: Jian Wang,Miles J. Padgett,Siddharth Ramachandran,Martin P.J. Lavery,Hao Huang,Yang Yue,Yan Yan,Nenad Bozinovic,Steven E. Golowich,Alan E. Willner

In this chapter, we provide a comprehensive review of multimode communications using OAM. The fundamentals of OAM are introduced first followed by the techniques for OAM generation, multiplexing/demultiplexing, and detection. We then present recent research efforts to free-space communication links and fiber-based transmission links using OAM multiplexing together with optical signal processing using OAM (data exchange, add/drop, multicasting, monitoring, and compensation). Future challenges of OAM communications are discussed at the end.

Hydro-Environmental Analysis

Freshwater Environments

By: James L. Martin

Focusing on fundamental principles, Hydro-Environmental Analysis: Freshwater Environments presents in-depth information about freshwater environments and how they are influenced by regulation. It provides a holistic approach, exploring the factors that impact water quality and quantity, and the regulations, policy and management methods that are necessary to maintain this vital resource. It offers a historical viewpoint as well as an overview and foundation of the physical, chemical, and biological characteristics affecting the management of freshwater environments. The book concentrates on broad and general concepts, providing an interdisciplinary foundation. The author covers the methods of measurement and classification; chemical, physical, and biological characteristics; indicators of ecological health; and management and restoration. He also considers common indicators of environmental health; characteristics and operations of regulatory control structures; applicable laws and regulations; and restoration methods. The text delves into rivers and streams in the first half and lakes and reservoirs in the second half. Each section centers on the characteristics of those systems and methods of classification, and then moves on to discuss the physical, chemical, and biological characteristics of each. In the section on lakes and reservoirs, it examines the characteristics and operations of regulatory structures, and presents the methods commonly used to assess the environmental health or integrity of these water bodies. It also introduces considerations for restoration, and presents two unique aquatic environments: wetlands and reservoir tailwaters. Written from an engineering perspective, the book is an ideal introduction to the aquatic and limnological sciences for students of environmental science, as well as students of environmental engineering. It also serves as a reference for engineers and scientists involved in the management, regulation, or restoration of freshwater environments.

Underlying Representations

By: Martin Krämer

At the heart of generative phonology lies the assumption that the sounds of every language have abstract underlying representations, which undergo various changes in order to generate the 'surface' representations; that is, the sounds we actually pronounce. The existence, status and form of underlying representations have been hotly debated in phonological research since the introduction of the phoneme in the nineteenth century. This book provides a comprehensive overview of theories of the mental representation of the sounds of language. How does the mind store and process phonological representations? Krämer surveys the development of the concept of underlying representation over the last 100 years or so within the field of generative phonology. He considers phonological patterns, psycholinguistic experiments, statistical generalisations over data corpora and phenomena such as hypercorrection. The book offers a new understanding of contrastive features and proposes a modification of the optimality-theoretic approach to the generation of underlying representations.
