Phase, Phase Signatures, and Simple Inverse Properties of Backscattered Fields from Thin Rods


Book Description

Numerical and analytical methods are used to examine properties of the phase of backscattered fields from perfectly conducting thin rods as functions of both aspect angle and frequency. Emphasis is placed on special conditions under which the phase is simply related to the body length and thickness. Calculated results are shown to be in good agreement with measured ones. Implications of the phase properties for dual frequency phase signatures are discussed and examples given. The amplitude of the backscattered field is shown to have a frequency-dependent shape that is essentially independent of aspect angle through the first resonant maximum. Measurement procedures that might be used to separately determine rod thicknesses and lengths are suggested. (Author).




Electron Backscatter Diffraction in Materials Science


Book Description

Electron backscatter diffraction is a very powerful and relatively new materials characterization technique aimed at the determination of crystallographic texture, grain boundary character distributions, lattice strain, phase identification, and much more. The purpose of this book is to provide the fundamental basis for electron backscatter diffraction in materials science, the current state of both hardware and software, and illustrative examples of the applications of electron backscatter diffraction to a wide-range of materials including undeformed and deformed metals and alloys, ceramics, and superconductors. The text has been substantially revised from the first edition, and the authors have kept the format as close as possible to the first edition text. The new developments covered in this book include a more comphrensive coverage of the fundamentals not covered in the first edition or other books in the field, the advances in hardware and software since the first edition was published, and current examples of application of electron backscatter diffraction to solve challenging problems in materials science and condensed-matter physics.
