Ground Penetrating Radar (GPR) is a powerful sensing technology widely used for the non-destructive assessment of a variety of structures with different properties including dimensions, electrical properties, and moisture. After an introduction to the underlying concepts, this book guides the reader through the development and use of a GPR system, with an emphasis on the parameters that can be optimized, the theory behind assessment, and a coherent methodology to obtain results from a measured or simulated GPR signal. The authors then embark on a detailed discussion of support tools and numerical modelling techniques that can be applied to improve readings from GPR systems. Ground Penetrating Radar is of interest to engineers, scientists, researchers and professionals working in the fields of ground penetrating radar, non-destructive testing, geoscience and remote sensing, antennas and propagation, microwaves, electromagnetics and imaging. It will also be of use to professionals and academics in the fields of electrical, mechanical, sensing, and civil engineering as well as material science and archaeology concerned with quality control and fault analysis.

Open resonator microwave sensors allow accurate sensing, monitoring and measurement of properties such as dimension and moisture content in materials including dielectrics, rubber, polymers, paper, fabrics and wood veneers. This book presents a coherent and entirely practical approach to the design and use of systems based on these sensors in industrial environments, showing how they can provide meaningful, accurate and industrially-viable methods of gauging. Starting with an introduction to the underlying theory, the book proceeds through the entire design process, including simulation, experimentation, prototyping and testing of a complete system. It takes the reader through the development of a particular sensor, stressing the parameters that should be optimized and emphasizing practical aspects of a sensor and of its use. Two extended application case studies on the use of these systems for rubber thickness and fabric coating monitoring are included.

Intended for undergraduate students of electrical engineering, this introduction to electromagnetic fields emphasizes the computation of fields as well as the development of theoretical relations. The first part thus presents the electromagnetic field and Maxwell's equations with a view toward connecting the disparate applications to the underlying relations, while the second part presents computational methods of solving the equations - which for most practical calses cannot be solved analytically.

Surface Impedance Boundary Conditions is perhaps the first effort to formalize the concept of SIBC or to extend it to higher orders by providing a comprehensive, consistent, and thorough approach to the subject. The product of nearly 12 years of research on surface impedance, this book takes the mystery out of the largely overlooked SIBC. It provides an understanding that will help practitioners select, use, and develop these efficient modeling tools for their own applications. Use of SIBC has often been viewed as an esoteric issue, and they have been applied in a very limited way, incorporated in computation as an ad hoc means of simplifying the treatment for specific problems. Apply a Surface Impedance "Toolbox" to Develop SIBCs for Any Application The book not only outlines the need for SIBC but also offers a simple, systematic method for constructing SIBC of any order based on a perturbation approach. The formulation of the SIBC within common numerical techniques-such as the boundary integral equations method, the finite element method, and the finite difference method-is discussed in detail and elucidated with specific examples. Since SIBC are often shunned because their implementation usually requires extensive modification of existing software, the authors have mitigated this problem by developing SIBCs, which can be incorporated within existing software without system modification. The authors also present: Conditions of applicability, and errors to be expected from SIBC inclusion Analysis of theoretical arguments and mathematical relationships Well-known numerical techniques and formulations of SIBC A practical set of guidelines for evaluating SIBC feasibility and maximum errors their use will produce A careful mix of theory and practical aspects, this is an excellent tool to help anyone acquire a solid grasp of SIBC and maximize their implementation potential.

This comprehensive two semester textbook, now in its 4th edition, continues to provide students with a thorough theoretical understanding of electromagnetic field relations while also providing numerous practical applications. The topics follow a tested pattern familiar to the previous edition, each with a brief, introductory chapter followed by a chapter with extensive treatment, 10 to 30 applications, examples and exercises, and problems and summaries. There is new emphasis on problems, examples and applications based on energy harvesting and renewable energy; additional information on sensing and actuation, new material on issues in energy, power, electronics, and measurements, and an emphasis on aspects of electromagnetics relevant to digital electronics and wireless communication. The author adds and revises problems to emphasize the use of tools such as Matlab; new advanced problems for higher level students; a discussion of symbolic and numerical integration; additional examples with each chapter; and new online material including experiments and review questions. The book is an undergraduate textbook at the upper division level, intended for required classes in electromagnetics. It is written in simple terms with all details of derivations included and all steps in solutions listed. It requires little beyond basic calculus and can be used for self-study. Features hundreds of examples and exercises, many new or revised for every topic in the book. Includes over 650 end-of-chapter problems, many of them new or revised, mostly based on applications or simplified applications. Includes a suite of online demonstration software including a computerized Smith Chart.

Sensors and actuators are used daily in countless applications to ensure more accurate and reliable workflows and safer environments. Many students and young engineers with engineering and science backgrounds often come prepared with circuits and programming skills but have little knowledge of sensors and sensing strategies and their interfacing. In this fully revised and expanded second edition, the author looks at sensors and actuators based on a broad area of detection methods. He takes a general and applications-oriented approach to the topic and makes it discipline-independent to cater for a broad audience. Important coverage is given to interfacing (the processes and mechanisms between the sensors and actuators) that makes systems work reliably and accurately. Topics covered include different type of sensors and actuators (temperature, thermal, optical, electric, magnetic, mechanical, acoustic, chemical, radiation, and smart sensors) and their interfaces. The book contains numerous examples and problem sets as well as useful appendices.

As sensors and actuators are normally not (and have not been) treated in academic curricula as a subject in its own right; many students and current professionals often find themselves limited in their knowledge and dealing with topics and issues based on material they may have never encountered. Until now. This book brings sensors, actuators and interfaces out of obscurity and integrates them for multiple disciplines including electrical, mechanical, chemical, and biomedical engineering. Real world cases, worked examples, and problem sets with selected answers provide both fundamental understanding and how industry develops sensor systems. Students and professionals from any of these disciplines will easily learn the foundational concepts and then be able to apply them to cross-discipline requirements. The idea is simple. A sensor system in general is made of three components: Inputs (sensors) Outputs (actuators) Processor (the unit to which the inputs and outputs are connected and performs all, or the most, tasks needed to interface them) Sensors, Actuators, and their Interfaces focuses on the broad area of detection, outlining and simplifying the understanding of theory behind sensing and actuation. It is an invaluable textbook for undergraduate and graduate level courses, as well as a reference for professionals who were never afforded the opportunity to take an introductory course.
