Electromechanical Coupling Theory, Methodology and Applications for High-Performance Microwave Equipment Electromechanical Coupling Theory, Methodology, and Applications for High-Performance Microwave Equipment is an authoritative and up-to-date guide to the structural, mechanical, and electrical aspects of electromechanical coupling. Addressing control, electromagnetism, and structural engineering, this comprehensive reference covers the electromechanical coupling of high-performance microwave electronic equipment (MEE), such as antennas, radar, large radio telescopes, and telecommunication and navigation equipment. The book is divided into four main sections, beginning with an introduction to electromechanical coupling (EMC) theory and a detailed description of the multi-field coupling model (MFCM) and the influence mechanism (IM) of nonlinear factors of antenna-servo-feeder systems on performance. Subsequent sections discuss MFCM- and IM-based design methodology, EMC-based measurement and testing, computer software for coupling analysis and design of electronic equipment, and various engineering applications of EMC theory and the IM of typical electronic equipment. In addition, the book: Discusses information and data transfer in electromagnetic fields, mechanical and structural deformation fields, and temperature fields Explains how high-performance microwave electronic equipment differs from traditional mechanical equipment Addresses EMC-based and general design-vector based optimization of electronic equipment design Describes applications such as a gun-guided radar system for warships and a large-diameter antenna for moon exploration Includes evaluation criteria to validate MFCM/IM design theory and methodology Electromechanical Coupling Theory, Methodology, and Applications for High-Performance Microwave Equipment is essential reading for circuit designers, microwave engineers, researchers working with high-frequency microwave engineering, and engineers working with integrated circuits in radar, communications, IoT, antenna engineering, and remote sensing.

The transformation of vibrations into electric energy through the use of piezoelectric devices is an exciting and rapidly developing area of research with a widening range of applications constantly materialising. With Piezoelectric Energy Harvesting, world-leading researchers provide a timely and comprehensive coverage of the electromechanical modelling and applications of piezoelectric energy harvesters. They present principal modelling approaches, synthesizing fundamental material related to mechanical, aerospace, civil, electrical and materials engineering disciplines for vibration-based energy harvesting using piezoelectric transduction. Piezoelectric Energy Harvesting provides the first comprehensive treatment of distributed-parameter electromechanical modelling for piezoelectric energy harvesting with extensive case studies including experimental validations, and is the first book to address modelling of various forms of excitation in piezoelectric energy harvesting, ranging from airflow excitation to moving loads, thus ensuring its relevance to engineers in fields as disparate as aerospace engineering and civil engineering. Coverage includes: Analytical and approximate analytical distributed-parameter electromechanical models with illustrative theoretical case studies as well as extensive experimental validations Several problems of piezoelectric energy harvesting ranging from simple harmonic excitation to random vibrations Details of introducing and modelling piezoelectric coupling for various problems Modelling and exploiting nonlinear dynamics for performance enhancement, supported with experimental verifications Applications ranging from moving load excitation of slender bridges to airflow excitation of aeroelastic sections A review of standard nonlinear energy harvesting circuits with modelling aspects.

Electromagnetic metamaterials-from fundamental physics to advanced engineering applications This book presents an original generalized transmission line approach associated with non-resonant structures that exhibit larger bandwidths, lower loss, and higher design flexibility. It is based on the novel concept of composite right/left-handed (CRLH) transmission line metamaterials (MMs), which has led to the development of novel guided-wave, radiated-wave, and refracted-wave devices and structures. The authors introduced this powerful new concept and are therefore able to offer readers deep insight into the fundamental physics needed to fully grasp the technology. Moreover, they provide a host of practical engineering applications. The book begins with an introductory chapter that places resonant type and transmission line metamaterials in historical perspective. The next six chapters give readers a solid foundation in the fundamentals and practical applications: Fundamentals of LH MMs describes the fundamental physics and exotic properties of left-handed metamaterials TL Theory of MMs establishes the foundations of CRLH structures in three progressive steps: ideal transmission line, LC network, and real distributed structure Two-Dimensional MMs develops both a transmission matrix method and a transmission line method to address the problem of finite-size 2D metamaterials excited by arbitrary sources Guided-Wave Applications and Radiated-Wave Applications present a number of groundbreaking applications developed by the authors The Future of MMs sets forth an expert view on future challenges and prospects This engineering approach to metamaterials paves the way for a new generation of microwave and photonic devices and structures. It is recommended for electrical engineers, as well as physicists and optical engineers, with an interest in practical negative refractive index structures and materials.
