The Springer Handbook of Augmented Reality presents a comprehensive and authoritative guide to Augmented Reality (AR) technology, its numerous applications, and its intersection with emerging technologies. This book traces the history of AR from its early development, discussing the fundamentals of AR and its associated science. Augmented Reality (AR) has been a topic of research for decades, but recent commercial interest and investments have made certain forms of AR available to hundreds of millions of users. AR generates the illusion, in real time, of 3D virtual objects appearing to exist in the real world around the user, either supplementing or modifying how users see their surroundings. Unlike Virtual Reality, which completely replaces what a user sees with a purely virtual 3D environment, AR retains the user’s view of the real world and modifies or supplements that with 3D digital objects and information. AR offers a new paradigm of how people view and interact with both digital information and the reality around them. It enables new interfaces and experiences that require combining real and virtual.

This book highlights advances in the field of THz engineering along with limitations of radio frequency (RF) technology. All engineering applications have been designed to operate over a specific frequency or wavelength range in electromagnetic spectrum. In recent years, the unexplored domain of THz range of electromagnetic spectrum has paved the way for terahertz technology due to its nonionizing nature and sensitivity to water content. A wide range of applications with THz techniques such as terahertz time-domain spectroscopy (THz-TDS), biological, medical and pharmaceutical sciences, explosives inspection, information and communication technology (ICT) sector and many more, have potential to be the technology of future. Different designing aspects and evolving application areas are addressed to enrich the technical knowledge of readers. This book provides an overview of state of the art in terms of research and industrial progress in THz spectrum.

Memristors have provided a new direction of thinking for circuit designers to overcome the limits of scalability and for thinking of building systems beyond Moore’s law. Over the last decade, there has been a significant number of innovations in using memristors for building neural networks through analog computing, in-memory computing, and stochastic computing approaches. The emergence of intelligent integrated circuits is inevitable for the future of integrated circuit applications.

This book discusses the evolution of multigate transistors, the design challenges of transistors for high-frequency applications, and the design and modeling of multigate transistors for high-frequency applications. The contents particularly focus on the cut-off frequency and maximum oscillation frequency of different multigate structures. RF stability modeling for multigate transistors is presented, which can help to understand the relation between the small-signal parameter and the physical parameter of the device for optimization. This is a useful reference to those in academia and industry. The transistor is one of the most important inventions in history which changed the world. The world is moving toward reducing the size of transistors to accommodate more in number, lesser power consumption, smaller delay, better performance, and reliability. However, the downscaling of conventional planar metal-oxide-semiconductor field-effect transistors (MOSFETs) is creating many problems such as the increase in leakage currents and short channel effects (SCEs). Most of the problems due to short channel effects and leakage currents in MOSFETs can be solved by improving the controllability of the gate.

Foundations of Antenna Radiation Theory Understand the theory and function of wireless antennas with this comprehensive guide. As wireless technology continues to develop, understanding of antenna properties and performance will only become more critical. Since antennas can be understood as junctions of waveguides, eigenmode analysis—the foundation of waveguide theory, concerned with the unexcited states of systems and their natural resonant characteristics—promises to be a crucial frontier in the study of antenna theory. Foundations of Antenna Radiation Theory incorporates the modal analysis, generic antenna properties and design methods discovered or developed in the last few decades, not being reflected in most antenna books, into a comprehensive introduction to the theory of antennas. This book puts readers into conversation with the latest research and situates students and researchers at the cutting edge of an important field of wireless technology.

This book offers a thorough exploration of the three-dimensional integration of resistive memory in all aspects, from the materials, devices, array-level issues, and integration structures, to its applications. Resistive random-access memory (RRAM) is one of the most promising candidates for next-generation nonvolatile memory applications owing to its superior characteristics including simple structure, high switching speed, low power consumption, and compatibility with standard complementary metal oxide semiconductor (CMOS) process. To achieve large-scale, high-density integration of RRAM, the 3D cross array is undoubtedly the ideal choice. This book introduces the 3D integration technology of RRAM, and breaks it down into five parts: 1) Associative Problems in Crossbar array and 3D architectures; 2) Selector Devices and Self-selective cells; 3) Integration of 3D RRAM; 4) Reliability Issues in 3D RRAM; 5) Applications of 3D RRAM Beyond Storage.

This text will help readers to gain knowledge about designing power electronic converters and their control for electric vehicles. It discusses the ways in which power from electric vehicle batteries is transferred to an electric motor, the technology used for charging electric vehicle batteries, and energy storage. The text covers case studies and real-life examples related to electric vehicles. Electric vehicles (EVs) have relatively high well-to-wheel efficiency, hence providing higher fuel economy and significantly reducing environmental pollution. Despite being a century-old concept, EVs were not popular in the past due to high cost, limited performance, short range, and long charging times. This book discusses the challenges, emerging technologies, and recent development of power electronics for electric vehicles. It will serve as an ideal reference text for graduate students and academic researchers in the fields of electrical engineering, electronics and communication engineering, environmental engineering, automotive engineering, and Computer Science.

This book investigates the most advanced theories and methodologies of array beamforming, with a focus on antenna array enabled wireless communication technology. Combining with the current development needs and trends of wireless communication technology around the world, the authors explore the potentials and challenges of large-scale antenna array beamforming technology in next-generation mobile communication and some important emerging application scenarios. The book first introduces the basic structure of antenna array hierarchical codebook and channel estimation with high dimensionality, with which the time cost of searching the channel information can be effectively reduced. It then explicates high-efficiency beamforming transmission methods for point-to-point transmission, full-duplex point-to-point transmission, and point-to-multipoint transmission where array beamforming enabled non-orthogonal multiple access (NOMA) technologies for typical two-user systems and general multi-user systems are emphasized.
