The present volume offers a clear description of the various neutron-scattering techniques currently being used to answer biologically relevant questions. Their utility is illustrated through examples by some of the leading researchers in the field of neutron scattering. This volume will be a reference for researchers and a step-by-step guide for young scientists entering the field and the advanced graduate student.
Описание: Quantum physics may appear complicated, especially if one forgets the "big picture" and gets lost in the details. However, it can become clearer and less tangled if one applies a few fundamental concepts so that simplified approaches can emerge and estimated orders of magnitude become clear. Povh and RosinaвЂ™s Scattering and Structures presents the properties of quantum systems (elementary particles, nucleons, atoms, molecules, quantum gases, quantum liquids, stars, and early universe) with the help of elementary concepts and analogies between these seemingly different systems. The original German-language edition of this book was written for students preparing for their final oral examination in physics. By and large, the scope of the book in English has been essentially enlarged and thus may also be of interest for physicists in general.
Описание: Space is a large natural plasma laboratory offering a wealth of phenomena which range from the simple to the highly complex and non-linear. This book begins with an introduction to basic principles such as single-particle motion, magnetohydrodynamics and plasma waves. It incorporates these concepts into an analysis of complex phenomena including the sun and solar activity, shocks, interplanetary space and magnetospheres, and finally the interaction between these entities in solar-terrestrial relationships. In all these subfields of space research, special attention is paid to energetic particles. The book concludes with a brief chapter on instrumentation. In this third edition, numerous examples have been added to illustrate the basic concepts and aid the reader in applying such concepts to real world physics. In addition, recent observations (ACE, TRACE, Wind) have been included. The chapter on solar-terrestrial relationships has been expanded to introduce the current research topic of Space Weather.
Описание: This textbook attempts to bridge the gap that exists between the two levels on which relativistic symmetry is usually presented вЂ“ the level of introductory courses on mechanics and electrodynamics and the level of application in high-energy physics and quantum field theory: in both cases, too many other topics are more important and hardly leave time for a deepening of the idea of relativistic symmetry. So after explaining the postulates that lead to the Lorentz transformation and after going through the main points special relativity has to make in classical mechanics and electrodynamics, the authors gradually lead the reader up to a more abstract point of view on relativistic symmetry вЂ“ always illustrating it by physical examples вЂ“ until finally motivating and developing WignerвЂ™s classification of the unitary irreducible representations of the inhomogeneous Lorentz group. Numerous historical and mathematical asides contribute to conceptual clarification.
Описание: This book covers both experimental and theoretical aspects of nanoscale light scattering and surface roughness.Topics include: Spherical particles located on a substrate, surface and buried interface roughness, surface roughness of polymer thin films, magnetic and thermal fluctuations at planar surfaces, speckle patterns, scattering of electromagnetic waves from a metal, multiple wavelength light scattering, nanoroughness standards, Beckmann-Kirchoff scalar scattering theory, random and nonrandom (patterned) surfaces, surface plasmons, instrumentation and experimental methods.
Описание: The evolution of our understanding of most properties of new functional materials is related to our knowledge of their atomic-scale structure. To further this, several X-ray and neutron techniques are employed. The anomalous X-ray scattering (AXS) method, exploiting the so-called anomalous dispersion effect near the absorption edge of the constituent element, is one of the most powerful methods for determining the accurate partial structure functions of individual pairs of constituents or the environmental functions around specific elements in multicomponent systems. AXS is useful for both crystalline and non-crystalline systems, for studies of surface and bulk materials. This book is the first on this new method of structural characterization. It describes the basics and application principles, and also treats the specifics of application to liquid alloys, supercooled liquids, solutions, metallic glasses, oxide glasses, superconducting ionic glasses etc.

Описание: Offers a discussion of light scattering by nonspherical particles and its practical applications. This book is suitable for graduate students, scientists, and engineers working on specific aspects of electromagnetic scattering by small particles and its applications in remote sensing, geophysics, astrophysics, and biomedical optics.
Описание: The present monograph deals with a particular class of approximation methods in the context of light scattering by small particles. This class of approximations has been termed as eikonal or soft particle approximations. The eikonal approximation was studied extensively in the potential scattering and then adopted in optical scattering problems. In this context, the eikonal and other soft particle approximations pertain to scatterers whose relative refractive index compared to surrounding medium is close to unity. The study of these approximations is very important because soft particles occur abundantly in nature. For example, the particles that occur in ocean optics, biomedical optics, atmospheric optics and in many industrial applications can be classified as soft particles. This book was written in recognition of the long-standing and current interest in the field of scattering approximations for soft particles. It should prove to be a useful addition for researchers in the field of light scattering.
Описание: Light Scattering by Systems of Particles comprehensively develops the theory of the null-field method, while covering almost all aspects and current applications. The Null-field Method with Discrete Sources is an extension of the Null-field Method (also called T-Matrix Method) to compute light scattering by arbitrarily shaped dielectric particles. It also incorporates FORTRAN programs and exemplary simulation results that demonstrate all aspects of the latest developments of the method. The FORTRAN source programs included on the enclosed CD exemplify the wide range of application of the T-matrix method. Worked examples of the application of the FORTRAN programs show readers how to adapt or modify the programs for his specific application.
Описание: This is the first book devoted specifically to the problem of light scattering and absorption by inhomogeneous and anisotropic spherical particles. Unlike other books in the field, Electromagnetic Scattering in Disperse Media pays considerable attention to various aspects of light absorption inside particles, including internal field distributions, MDR resonances, and absorption in restricted regions inside particles. It contains many results (and more than 100 figures) computed for polydisperse particle systems and algorithms and provides the possibility to use them (web site). Although the main emphasis is given to optical properties of atmospheric aerosol, the book also deals with many other practical applications involving inhomogeneous and anisotropic particles.
Описание: Wave scattering by discrete scatterers is an interdisciplinary area of research with many applications in such areas as atomic physics, medical imaging, geoscience and remote sensing. This three-volume work is an expanded and updated version of the authors 1985 book, Theory of Microwave Remote Sensing. It incorporates recent research and its scope has been greatly expanded to appeal to a much wider audience. While the emphasis of these books remains on remote sensing applications, they are useful for researchers in such areas as composite materials, photonic devices, optical thin films, lasers, optical tomography and x-ray lithography.
