Book Synopsis Backscattered Spectra from Rotating and Vibrating Short Wires and Their Relation to the Identification Problem by : Ronald G. Newburgh
Download or read book Backscattered Spectra from Rotating and Vibrating Short Wires and Their Relation to the Identification Problem written by Ronald G. Newburgh and published by . This book was released on 1975 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the report Rayleigh scattering for a short wire is examined for two simple motions, rotation and vibration. Rotation of the wire causes an amplitude modulation and vibration causes a phase modulation. Each of these modulations influences the backscattered spectra so that the characteristic frequency of the periodic motion appears. For the rotating wire, it is twice the rotation frequency. From the spectra it is possible to recognize the type of motion responsible. The study therefore serves as a first step in the development of models for complicated motions of actual objects such as tanks and trucks, thereby leading to possible vehicle signature classification schemes. The appendices include: a brief discussion of the formalism of polarization scattering matrices; a short examination of the relation between the scattered spectra due to periodic motions and the conventional Doppler effect; and an examination of the analogy between the rotating and vibrating wires and molecules as conventional Raman scatters, including a brief section on the energetics of the scattering process.

Book Synopsis Electromagnetic Scattering by a Linearly Oscillating Target by : Ralph E. Kleinman
Download or read book Electromagnetic Scattering by a Linearly Oscillating Target written by Ralph E. Kleinman and published by . This book was released on 1975 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: A theoretical analysis is presented in this report which shows that when a plane electromagnetic wave is incident upon a perfectly conducting, linearly oscillating, arbitrarily shaped target, the scattered far field differs only in phase from the field scattered when the target is motionless. The explicit form of the phase modulation factor is derived to an accuracy of the order of v/c, where v and c are the velocities of target motion and electromagnetic waves respectively. Spectral analysis of the modulation shows that the power distribution varies with the shape of the motion, wavelength of the incident field, and magnitude of the projections of the oscillation in the incident and receiver directions. Power spectra are calculated for square, triangular, and sinusoidal periodic target motion as well as a superposition of two sinusoids of different frequency and amplitude. The results indicate that even small amplitude oscillations produce measurable modulations of the scatter field. (Author).

Book Synopsis Optical Properties of Solids by : Frederick Wooten
Download or read book Optical Properties of Solids written by Frederick Wooten and published by Academic Press. This book was released on 2013-10-22 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical Properties of Solids covers the important concepts of intrinsic optical properties and photoelectric emission. The book starts by providing an introduction to the fundamental optical spectra of solids. The text then discusses Maxwell's equations and the dielectric function; absorption and dispersion; and the theory of free-electron metals. The quantum mechanical theory of direct and indirect transitions between bands; the applications of dispersion relations; and the derivation of an expression for the dielectric function in the self-consistent field approximation are also encompassed. The book further tackles current-current correlations; the fluctuation-dissipation theorem; and the effect of surface plasmons on optical properties and photoemission. People involved in the study of the optical properties of solids will find the book invaluable.
Book Synopsis A Short Course on Topological Insulators by : János K. Asbóth
Download or read book A Short Course on Topological Insulators written by János K. Asbóth and published by Springer. This book was released on 2016-02-22 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This course-based primer provides newcomers to the field with a concise introduction to some of the core topics in the emerging field of topological insulators. The aim is to provide a basic understanding of edge states, bulk topological invariants, and of the bulk--boundary correspondence with as simple mathematical tools as possible. The present approach uses noninteracting lattice models of topological insulators, building gradually on these to arrive from the simplest one-dimensional case (the Su-Schrieffer-Heeger model for polyacetylene) to two-dimensional time-reversal invariant topological insulators (the Bernevig-Hughes-Zhang model for HgTe). In each case the discussion of simple toy models is followed by the formulation of the general arguments regarding topological insulators. The only prerequisite for the reader is a working knowledge in quantum mechanics, the relevant solid state physics background is provided as part of this self-contained text, which is complemented by end-of-chapter problems.
Book Synopsis Springer Handbook of Microscopy by : Peter W. Hawkes
Download or read book Springer Handbook of Microscopy written by Peter W. Hawkes and published by Springer Nature. This book was released on 2019-11-02 with total page 1561 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book features reviews by leading experts on the methods and applications of modern forms of microscopy. The recent awards of Nobel Prizes awarded for super-resolution optical microscopy and cryo-electron microscopy have demonstrated the rich scientific opportunities for research in novel microscopies. Earlier Nobel Prizes for electron microscopy (the instrument itself and applications to biology), scanning probe microscopy and holography are a reminder of the central role of microscopy in modern science, from the study of nanostructures in materials science, physics and chemistry to structural biology. Separate chapters are devoted to confocal, fluorescent and related novel optical microscopies, coherent diffractive imaging, scanning probe microscopy, transmission electron microscopy in all its modes from aberration corrected and analytical to in-situ and time-resolved, low energy electron microscopy, photoelectron microscopy, cryo-electron microscopy in biology, and also ion microscopy. In addition to serving as an essential reference for researchers and teachers in the fields such as materials science, condensed matter physics, solid-state chemistry, structural biology and the molecular sciences generally, the Springer Handbook of Microscopy is a unified, coherent and pedagogically attractive text for advanced students who need an authoritative yet accessible guide to the science and practice of microscopy.
