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.

Ultrasound B-mode Imaging: Beamforming and Image Formation Techniques


Book Description

Ultrasound medical imaging stands out among the other diagnostic imaging modalities for its patient-friendliness, high temporal resolution, low cost, and absence of ionizing radiation. On the other hand, it may still suffer from limited detail level, low signal-to-noise ratio, and narrow field-of-view. In the last decade, new beamforming and image reconstruction techniques have emerged which aim at improving resolution, contrast, and clutter suppression, especially in difficult-to-image patients. Nevertheless, achieving a higher image quality is of the utmost importance in diagnostic ultrasound medical imaging, and further developments are still indispensable. From this point of view, a crucial role can be played by novel beamforming techniques as well as by non-conventional image formation techniques (e.g., advanced transmission strategies, and compounding, coded, and harmonic imaging). This Special Issue includes novel contributions on both ultrasound beamforming and image formation techniques, particularly addressed at improving B-mode image quality and related diagnostic content. This indeed represents a hot topic in the ultrasound imaging community, and further active research in this field is expected, where many challenges still persist.




Wideband Microwave Materials Characterization


Book Description

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.
