Determining intrinsic microwave properties or extrinsic performance of materials is important for a variety of applications, including wireless propagation, antenna and microwave circuit design, and remote sensing, among others. This practical engineering guide to microwave material measurements discusses both laboratory and manufacturing/field environments. Modern technology has created a need to adapt microwave measurement methods for in-line quality assurance, in-situ process control, and field inspection of materials and components. Various configurations for free-space measurements are covered, as well as guidance on calibration methods, signal processing, and intrinsic property inversion algorithms. You will learn how the modern adaptation of impedance analysis to CEM inversion methods and how this powerful new technique can be used to significantly improve conventional measurement methods. Intended to inform engineers and scientists of the theory and practice of wide-band microwave characterization of materials, this guide provides the necessary theory and equations for implementing these methods and gives hints and techniques for their practical implementation.
This book is a practical engineering guide to microwave material measurements for both laboratory and manufacturing/field environments, including nondestructive inspection (NDI) and nondestructive evaluation (NDE). The book covers proven methods for characterizing materials at microwave frequencies, including both resonant and wide-bandwidth techniques, and gives you the necessary theory and equations for implementing these methods. You'll understand how to invert dielectric and/or magnetic material properties from free space transmission and reflection, and how to measure traveling wave attenuation. You'll also know how to measure dielectric and/or magnetic material properties from transmission line fixtures, and learn how to use computational electromagnetic modeling with a measurement fixture. The book shows you how to build and use microwave NDE equipment for radomes and/or structural dielectric materials. This is an excellent resource for Engineers/scientists conducting or analyzing RF/Microwave/MMW material measurements for applications in electromagnetic materials, as well as those who are developing or applying microwave non-destructive evaluation (NDE) methods to their manufacturing problems.
