The first of its kind, this comprehensive work details the theory and practical design of new multi-band filters.
Learn how new materials and electronics technologies can make RFID systems more energy efficient and environmentally friendly. Experts show you how energy scavenging, passive/chipless RFID, RFID passive sensors, networked RFID, energy harvesting, organic devices, and wide area electronics can be used to develop green solutions for the Internet of Things.
Electromagnetic materials can be widely found in daily life, especially in electronic devices. The high-frequency properties (permittivity or permeability) of these materials strongly depend on structure, composition, shape, and orientation. Therefore, this book intends to present readers with advances not only in materials science (including metamaterials), but also in measurements and novel functional applications that demand the special properties of electromagnetic materials.
Discover a modern approach to the analysis, modeling and design of high sensitivity phased arrays. Network theory, numerical methods and computational electromagnetic simulation techniques are uniquely combined to enable full system analysis and design optimization. Beamforming and array signal processing theory are integrated into the treatment from the start. Digital signal processing methods such as polyphase filtering and RFI mitigation are described, along with technologies for real-time hardware implementation. Key concepts from interferometric imaging used in radio telescopes are also considered. A basic development of theory and modeling techniques is accompanied by problem sets that guide readers in developing modeling codes that retain the simplicity of the classical array factor method while incorporating mutual coupling effects and interactions between elements. Combining current research trends with pedagogical material suitable for a first-year graduate course, this is an invaluable resource for students, teachers, researchers, and practicing RF/microwave and antenna design engineers.
A one-stop tutorial for beginners covering the fundamentals of microwave imaging, including application examples and practical exercises.
An in-depth look at the state-of-the-art in microwave filter design, implementation, and optimization Thoroughly revised and expanded, this second edition of the popular reference addresses the many important advances that have taken place in the field since the publication of the first edition and includes new chapters on Multiband Filters, Tunable Filters and a chapter devoted to Practical Considerations and Examples. One of the chief constraints in the evolution of wireless communication systems is the scarcity of the available frequency spectrum, thus making frequency spectrum a primary resource to be judiciously shared and optimally utilized. This fundamental limitation, along with atmo...

Magnetic spinels including ferrites are insulating magnetic oxides and chalcogenides with strong coupling to microwave frequencies and low eddy current losses making them indispensable for applications in wireless communications. The 13 chapters and preface of this book discuss other potential applications of magnetic spinels along with various methods used for their synthesis and their varied properties resulting from substituting different metal ions at the A and B sites. These applications include ferrofluids, anticorrosion coatings, absorber coatings for photothermal conversion, biomedicine, and environmental applications such as oxidation of volatile organic compounds and removal of arsenic and heavy metals from water. Emphasis is placed on structure-property correlations and on the nature of magnetism in spinels and their nanoparticles with current information provided for future research.
This book reports on recent progress in emerging technologies, modern characterization methods, theory and applications of advanced magnetic materials. It covers broad spectrum of topics: technology and characterization of rapidly quenched nanowires for information technology; fabrication and properties of hexagonal ferrite films for microwave communication; surface reconstruction of magnetite for spintronics; synthesis of multiferroic composites for novel biomedical applications, optimization of electroplated inductors for microelectronic devices; theory of magnetism of Fe-Al alloys; and two advanced analytical approaches for modeling of magnetic materials using Everett integral and the inverse problem approach. This book is addressed to a diverse group of readers with general background in physics or materials science, but it can also benefit specialists in the field of magnetic materials.
Single mode equivalent network representations have been a key tool for the industrial design and development of a large variety of microwave systems. The reduced dimensions and increased complexity of modern microwave equipment, however, makes the inclusion of the higher order mode interactions essential for the correct industrial design and optimization of all microwave hardware. In this context, the analytical techniques originally exploited to develop single mode networks have recently been extended to produce multi-mode algorithms that can form the basis of fast and accurate Computer Aided Design tools. Furthermore, alternative multi-modal techniques, involving resonant rather than guid...
