Non-standard Antennas
This book aims at describing the wide variety of new technologies and concepts of non-standard antenna systems – reconfigurable, integrated, terahertz, deformable, ultra-wideband, using metamaterials, or MEMS, etc, and how they open the way to a wide range of applications, from personal security and communications to multifunction radars and towed sonars, or satellite navigation systems, with space-time diversity on transmit and receive. A reference book for designers in this lively scientific community linking antenna experts and signal processing engineers.
Innovative Materials and Systems for Energy Harvesting Applications
Wearable electronics, wireless devices, and other mobile technologies have revealed a deficit and a necessity for innovative methods of gathering and utilizing power. Drawing on otherwise wasted sources of energy, such as solar, thermal, and biological, is an important part of discovering future energy solutions. Innovative Materials and Systems for Energy Harvesting Applications reports on some of the best tools and technologies available for powering humanity’s growing thirst for electronic devices, including piezoelectric, solar, thermoelectric, and electromagnetic energies. This book is a crucial reference source for academics, industry professionals, and scientists working toward the future of energy.
Wireless Identification and Sensing Systems for Harsh and Severe Environments
Comprehensive resource reviewing the state of the artin wireless identification and sensing systems, proposing several examples of applications While complying with RF standard and regulations, Wireless Identification and Sensing Systems for Harsh and Severe Environments covers the recent advances in wireless and radio-frequency identification (RFID) systems where severe electromagnetic behavior and harsh conditions are taken into consideration, providing the reader with design rules and methodologies to obtain satisfactory performance and avoid the typical oversights and mistakes that can be made when first approaching this topic. In addition to examples of real implementations, the book gi...
Nuclear Physics 2
Nuclear Physics 2 explores the applications of various radioisotopes for dating and nuclear medicine imaging. It introduces the theoretical and experimental facts from the observation of the red shift in the spectrum of galaxies (1913), and the discovery of the cosmic microwave background (1965) that led to the validation of the Big Bang model, through which all known chemical elements are created via nucleosynthesis processes. This introduction is followed by a description of the nuclear reactions involved in primordial, stellar, and explosive. The principles of carbon-14, potassium-argon, uranium-thorium and uranium-protactinium dating, along with the principles of lead-210, caesium-137 an...
Nuclear Physics 3
Nuclear Physics 3 presents the applications of various radioisotopes in nuclear medicine, with a focus on radiological imaging methods such as X-rays, γ scintigraphy – PET – MRI and ultrasound, which do not exploit the properties of radiopharmaceuticals. The book then presents the physicochemical and pharmacological properties of radiopharmaceuticals labeled with 99mTc, 201Tl, 18mKr, 18F and the radioisotopes 123I, 125I and 131I used in nuclear medicine. The production chains for the radiotracers studied, as well as their main emissions, are then described in detail, followed by a study of the clearance mechanisms of the radiopharmaceuticals under consideration. Finally, the book describes the principles of myocardial, pulmonary, bone, thyroid, renal and gastric emptying scans using the properties of the radiotracers studied, as well as the principles of prostate brachytherapy using iodine-125 implants and prostate chemotherapy.
Recording and Voice Processing, Volume 1
Capturing, recording and broadcasting the voice is often difficult. Many factors must be taken into account and achieving a true representation is much more complex than one might think. The capture devices such as the position of the singer(s) or narrator(s), the acoustics, atmosphere and equipment are just some of the physical aspects that need to be mastered. Then there is the passage through the analog or digital channel, which disrupts the audio signal, as well as the processes that are often required to enrich, improve or even transform the vocal timbre and tessitura. While in the past these processes were purely material, today digital technologies and software produce surprising resu...
The Wave Concept in Electromagnetism and Circuits
The Wave Concept Iterative Procedure (WCIP) method has found an increasing number of users within electromagnetic theory and applications to planar circuits, antennas and diffraction problems. This book introduces in detail this new formulation of integral methods, based on the use of a wave concept with two bounded operators, and applications in a variety of domains in electromagnetics. This approach presents a number of benefits over other integral methods, including overcoming the problem of singularity, and reduced computing time. Through the presentation of mathematical equations to characterize studied structures and explanation of the curves obtained, via validated examples, the authors provide a thorough background to electromagnetism as well as a professional reference to students and researchers.
Human Exposure to Electromagnetic Fields
Everyone, whether they like it or not, is exposed to electromagnetic fields, most of the time, at very low levels. In this case, they are inconsequential, but they can cause adverse health effects when they become intense enough. This topic is complex and sensitive. Covering frequencies from 0 Hz to 300 GHz, Human Exposure to Electromagnetic Fields provides an overview of this vast topic. After a reminder of the concepts of electromagnetic fields, the author presents some examples of sources of radiation in daily life and in the industrial or medical sectors. The biophysical and biological effects of these fields on the human body are detailed and the exposure limits are recalled. The exposure assessment and the implementation of the appropriate regulation within companies are also covered. Technically and practically, this book is aimed at people with a scientific background, risk prevention actors, health physicians, especially occupational doctors, and equipment designers.
Fundamentals and Applications of Acoustic Metamaterials
In the last few decades, metamaterials have revolutionized the ways in which waves are controlled, and applied in physics and practical situations. The extraordinary properties of metamaterials, such as their locally resonant structure with deep subwavelength band gaps and their ranges of frequency where propagation is impossible, have opened the way to a host of applications that were previously unavailable. Acoustic metamaterials have been able to replace traditional treatments in several sectors, due to their better performance in targeted and tunable frequency ranges with strongly reduced dimensions. This is a training book composed of nine chapters written by experts in the field, giving a broad overview of acoustic metamaterials and their uses. The book is divided into three parts, covering the state-of-the-art, the fundamentals and the real-life applications of acoustic metamaterials.
