It is divided into two parts: Part 1, including original contributions on advanced techniques for the characterization of dielectric materials, and Part 2, devoted to the microwave characterization of biological tissues.




EM Material Characterization Techniques for Metamaterials


Book Description

This book presents a review of techniques based on waveguide systems, striplines, freespace systems and more, discussing the salient features of each method in detail. Since metamaterials are typically inhomogeneous and anisotropic, the experimental techniques for electromagnetic (EM) material characterization of metamaterial structures need to tackle several challenges. Furthermore, the modes supported by metamaterial structures are extremely sensitive to external perturbations. As such the measurement fixtures for EM material characterization have to be modified to account for such effects. The book provides a valuable resource for researchers working in the field of metamaterials




Focused Beam Methods


Book Description

Determining the intrinsic microwave properties of materials is important for a variety of applications ranging from antenna and electronic circuit design to remote sensing to electromagnetic interference mitigation. A number of methods exist for characterizing intrinsic properties of materials at microwave frequencies, including transmission lines, resonant cavities, and impedance analysis. The use of free-space measurement methods has become commonplace among microwave material characterization laboratories due to its ease of use and reasonable accuracy. While some free-space facilities exist that can characterize down to 500 MHz, the method is most useful for characterizing materials from 2 GHz through millimeter waves. This book is designed to acquaint engineers and scientists with the theory and practice of using microwave focused beam systems for free-space characterization of materials.

Advanced Techniques for Materials Characterization


Book Description

Volume is indexed by Thomson Reuters BCI (WoS). Nowadays, an impressively large number of powerful characterization techniques is being used by physicists, chemists, biologists and engineers in order to solve analytical research problems; especially those related to the investigation of the properties of new materials for advanced applications. Although there are a few available books which deal with such experimental techniques, they are either too exhaustive and cover very few techniques or are too elementary to provide a solid basis for learning to use the characterization technique. Moreover, such books usually over-emphasize the textbook approach: being full of theoretical concepts and mathematical derivations, and omitting the practical instruction required in order to permit newcomers to use the techniques.
