Book Synopsis Guiding, Diffraction, and Confinement of Optical Radiation by : Salvatore Solimeno
Download or read book Guiding, Diffraction, and Confinement of Optical Radiation written by Salvatore Solimeno and published by Elsevier. This book was released on 2012-12-02 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: Guiding, Diffraction, and Confinement of Optical Radiation presents a wide array of research studies on optics and electromagnetism. This book is organized into eight chapters that cover the problems related to optical radiation propagation and confinement. Chapter I examines the general features of electromagnetic propagation and introduces the basic concepts pertaining to the description of the electromagnetic field and its interaction with matter. Chapter II is devoted to asymptotic methods of solution of the wave equation, with particular emphasis on the asymptotic representation of the field in the form of the Luneburg-Kline series. This chapter also looks into a number of optical systems characterized by different refractive index distributions relying on the eikonal equation. Chapter III deals with stratified media, such as the multilayered thin films, metallic and dielectric reflectors, and interference filters. Chapters IV and V discuss the problem of propagation and diffraction integrals. Chapter VI describes the scattering from obstacles and the metallic and dielectric gratings. Chapters VII considers the passive and active resonators employed in connection with laser sources for producing a confinement near the axis of an optical cavity and Fabry-Perot interferometers and mainly relies on the use of diffraction theory. Chapter VIII presents the analytic approach to the study of transverse confinement near the axis of a dielectric waveguide hinges on the introduction of modal solutions of the wave equation. This book will be of value to quantum electronics engineers, physicists, researchers, and optics and electromagnetism graduate students.

This book was released on 2021-03-16 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le livre est composé de huit chapitres, exposés de façon particulièrement claire et précise, puis complétés chacun par des exercices d’application corrigés. Les deux premiers chapitres précisent les notions de base essentielles en optique. Ce sont d’abord les modèles permettant de décrire la lumière et les sources lumineuses, puis quelques notions sur la matière expliquant l’émission par incandescence et par luminescence. Ce sont également des notions de radiométrie et de photométrie, complétées par un descriptif de qualification normative des éclairages. Les autres chapitres développent plus particulièrement l’optique ondulatoire. Quelques généralités nécessaires sur les interférences sont suivies de l’étude plus précise d’interférences localisées produites par une lame, avec notamment leur application au traitement des surfaces. La diffraction de Fraunhofer est étudiée et illustrée dans les cas de la fente fine et de l’ouverture circulaire. Sa conséquence sur la limite de résolution des instruments d’optique est également analysée. Une étude détaillée de la diffraction par un réseau est réalisée. Enfin sont décrites et illustrées les notions de polarisation et de biréfringence (naturelle et provoquée).

Download or read book Diffraction written by M. Françon and published by Elsevier. This book was released on 2013-10-22 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diffraction: Coherence in Optics presents a detailed account of the course on Fraunhofer diffraction phenomena, studied at the Faculty of Science in Paris. The publication first elaborates on Huygens' principle and diffraction phenomena for a monochromatic point source and diffraction by an aperture of simple form. Discussions focus on diffraction at infinity and at a finite distance, simplified expressions for the field, calculation of the path difference, diffraction by a rectangular aperture, narrow slit, and circular aperture, and distribution of luminous flux in the airy spot. The book then examines Fourier transformation and diffraction by several apertures. The manuscript takes a look at extended luminous sources and objects and diffraction phenomena in perfect optical instruments. Topics include diffraction gratings, phase contrast, apodization, filtering spatial frequencies, relation between the length of wave trains and the spectral width of the emitted radiations, successive wave trains emitted by an atom, and vibrations with different frequencies from a single atom. The manuscript also reviews diffraction phenomena in real optical instruments, including diffraction in the case of a spherical wave and diffraction spot in the presence of aberrations. The publication is a dependable reference for readers interested in diffraction phenomena.
Book Synopsis Mathematical Theory of Diffraction by : Arnold Sommerfeld
Download or read book Mathematical Theory of Diffraction written by Arnold Sommerfeld and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: A. Sommerfeld's "Mathematische Theorie der Diffraction" marks a milestone in optical theory, full of insights that are still relevant today. In a stunning tour de force, Sommerfeld derives the first mathematically rigorous solution of an optical diffraction problem. Indeed, his diffraction analysis is a surprisingly rich and complex mix of pure and applied mathematics, and his often-cited diffraction solution is presented only as an application of a much more general set of mathematical results. This complete translation, reflecting substantial scholarship, is the first publication in English of Sommerfeld's original work. The extensive notes by the translators are rich in historical background and provide many technical details for the reader.

Download or read book Diffraction X-ray Optics, written by A.I. Erko and published by CRC Press. This book was released on 1996 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diffraction X-ray Optics provides a systematic description of the performance and mathematical properties of diffraction x-ray optical elements based upon artificially made microstructures. This description is presented both theoretically (using kinematic diffraction theory and classical optics) and experimentally (including details of the experimental verification of theoretical data). The microstructures which are considered include: plane zone plates, two and three dimensional gratings, multilayer mirrors and three dimensional Fresnel structures. The book also includes a detailed description of the main principles, technology and applications of both Bragg-Fresnel multilayer optics and x-ray Fourier optics. Special attention is paid to coherent phenomena in the x-ray region, x-ray holography and Bragg-Fresnel optics and with chapters covering absorption and refraction, planar diffraction, volume holography, fabrication techniques and microscopy this book will prove a useful sourcebook to both researchers and development engineers in the field.
