Uniquely explains in detail how small antennas work and ways to improve their performance This book addresses the recent significant theoretical and practical developments in the electrically small antenna (ESA) area. Examining antenna designs that work as well as those that have limitations, it offers the latest information on electromagnetically coupled structures and improving bandwidth using spherical helix dipoles, the exact derivation of Q for electrically small antennas for both TE and TM modes, a new simplified Q formula developed by the authors, and discussions of metamaterials and computer model accuracy for ESA. The book begins with detailed electromagnetic derivations of Chu and Thal Q formulations, formulas for Q when U or E cores are used, and effects of loss on Q. It also includes a treatise on bandwidth and matching, and Foster's reactance theorem, as well as up-to-date coverage of canonical antennas: dipoles, loops, self-resonant ESA, PIFA, and dielectric resonator antennas. Just as this book offers the concrete facts on relevant developments in the field, it also clears up confusion regarding findings that have not turned out to be useful. Presented here are antenna ideas that are clever but with performance numbers that are poor, as well as eighteen more antenna ideas that are simply not to be believed. The book concludes with recent data on the use of self-resonant elements in superdirective antennas and new delay line data on superconducting antennas. Each chapter features extensive references and an author list. In addition, helpful appendices cover a world history of ESA, antenna terms important to ESA, a paper on NIM shells enclosing an ESA dipole, and analytical errors associated with perfect lenses and sub-wavelength focusing. Small Antenna Handbook is ideal for practicing engineers in the telecommunications and national defense areas, as well as for upper-level undergraduate and graduate students.

Over the past decade, the world has witnessed an explosion in the
development and deployment of new wireless network technologies.
From cellular mobile telephony to the ubiquitous "WiFi" networks in
coffee-shops and airports, to the emerging WiMAX wireless broadband
access networks, the menu of wireless access systems has become so
comprehensive that wireline access to user devices may soon become
a relic of the past. Wireless Networking serves as a one-stop view
of cellular, WiFi, and WiMAX networks, as well as the emerging
wireless ad hoc and sensor networks. Rather than provide
descriptive accounts of these technologies and standards, the book
emphasizes conceptual perspectives on the modeling, analysis,
design and optimization of such networks. Furthermore, the authors
present wireless networking within the unifying framework of
resource allocation, using simple abstractions of the underlying
physical wireless communication. In short, Wireless Networking is
an in-depth, exhaustive, and invaluable asset to anyone working in
this rapidly evolving field.
This book offers an intuitive approach to random processes and educates the reader on how to interpret and predict their behavior. Premised on the idea that new techniques are best introduced by specific, low-dimensional examples, the mathematical exposition is easier to comprehend and more enjoyable, and it motivates the subsequent generalizations. It distinguishes between the science of extracting statistical information from raw data--e.g., a time series about which nothing is known a priori--and that of analyzing specific statistical models, such as Bernoulli trials, Poisson queues, ARMA, and Markov processes. The former motivates the concepts of statistical spectral analysis (such as the Wiener-Khintchine theory), and the latter applies and interprets them in specific physical contexts. The formidable Kalman filter is introduced in a simple scalar context, where its basic strategy is transparent, and gradually extended to the full-blown iterative matrix form.
The subject of Discrete Signals and Systems is broad and deserves a single book devoted to it. The objective of this textbook is to present all the required material that an undergraduate student will need to master this subject matter and the use of MATLAB. This book is primarily intended for electrical and computer engineering students, and especially for use by juniors or seniors in these undergraduate engineering disciplines. It can also be very useful to practicing engineers.

The book is ideal for a one-semester course in the area of discrete linear systems or digital signal processing, where the instructor can cover all chapters with ease. Numerous examples are presented within each chapter to illustrate each concept when and where it is presented. Most of the worked-out examples are first solved analytically and then solved using MATLAB in a clear and understandable fashion.
This textbook is based on 20 years of teaching a graduate-level course in random processes to a constituency extending beyond signal processing, communications, control, and networking, and including in particular circuits, RF and optics graduate students. In order to accommodate today's circuits students' needs to understand noise modeling, while covering classical material on Brownian motion, Poisson processes, and power spectral densities, the author has inserted discussions of thermal noise, shot noise, quantization noise and oscillator phase noise. At the same time, techniques used to analyze modulated communications and radar signals, such as the baseband representation of bandpass random signals, or the computation of power spectral densities of a wide variety of modulated signals, are presented. This book also emphasizes modeling skills, primarily through the inclusion of long problems at the end of each chapter, where starting from a description of the operation of a system, a model is constructed and then analyzed. Provides semester-length coverage of random processes, applicable to the analysis of electrical and computer engineering systems; Designed to be accessible to students with varying backgrounds in undergraduate mathematics and engineering; Includes solved examples throughout the discussion, as well as extensive problem sets at the end of every chapter; Develops and reinforces student's modeling skills, with inclusion of modeling problems in every chapter; Solutions for instructors included.

Mobile communication systems rely on radiofrequency waves to operate. Given the popularity and ubiquity of mobile communication devices as well as network densification, the level of Electromagnetic Field (EMF) exposure to the public is expected to rise significantly over the next few years. Although there is no clear evidence linking short-term exposure to EMF emission from wireless communication systems with adverse health effects, the International Agency for Research on Cancer (IARC) has concluded that EMF radiation is possibly carcinogenic. To cope with the concerns of the general public, the European Environmental Agency has recommended non-technical precautionary approaches to minimize exposure to EMF emissions. Rather than relying on these non-technical approaches, EMF, latency, network resilience and connection density, alongside traditional criteria such as spectral efficiency and energy efficiency are expected to take centre stage in the development of 5G systems. This book focuses on innovative EMF exposure research for future generations of mobile and wireless communications. This timely publication highlights the novel work done on reducing EMF emissions in future mobile communication systems and how to develop smart integrated technical solutions.
RFID is a method of remotely storing and receiving data using
devices called RFID tags. RFID tags can be small adhesive stickers
containing antennas that receive and respond to transmissions from
RFID transmitters. RFID tags are used to identify and track
everything from Exxon EZ pass to dogs to beer kegs to library
books.
The hidden costs of artificial intelligence—from natural resources and labor to privacy, equality, and freedom. What happens when artificial intelligence saturates political life and depletes the planet? How is AI shaping our understanding of ourselves and our societies? Drawing on more than a decade of research, award‑winning scholar Kate Crawford reveals how AI is a technology of extraction: from the minerals drawn from the earth to the labor pulled from low-wage information workers to the data taken from every action and expression. Crawford reveals how this planetary network is fueling a shift toward undemocratic governance and increased inequity. Rather than taking a narrow focus on code and algorithms, Crawford offers us a material and political perspective on what it takes to make AI and how it centralizes power. This is an urgent account of what is at stake as technology companies use artificial intelligence to reshape the world.
The book highlights three types of technologies being developed for autonomous solution of navigation problems. These technologies are based on the polarization structure, ultra-broadband and the fluctuation characteristics (slow and fast) of the radiolocation signals. The book presents the problems of intrinsic thermal radio emission polarization and change in radio waves polarization when they are reflected from objects with non-linear properties. The purpose of this book is to develop the foundations for creating autonomous radionavigation systems to provide aviation with navigation systems that will substantially increase its capabilities, specifically acting where satellite technologies do not work. The book is intended for specialists involved in the development and operation of aviation-technical complexes, as well as for specialists of national aviation regulators and ICAO experts dealing with the problems of improving flight safety.
