This book was released on 2017 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Given the many different applications and uses of diffractive optics, the importance of this field cannot be underestimated. This book supplements the available literature on diffractive optic elements (DOEs) by equipping readers with the skills to begin designing, simulating, and fabricating diffractive optics. The design of DOEs is presented with simple equations and step-by-step procedures for simulation--from the simplest 1D grating to the more complex multifunctional DOEs--and analyzing their diffraction patterns using MATLAB. The fundamentals of fabrication techniques such as photolithography, electron beam lithography, and focused ion beam lithography with basic instructions for the beginner are presented. Basic error analysis and error-correction techniques for a few cases are also discussed. The contents of all the chapters are supported throughout by practical exercises and clearly commented MATLAB® codes (the codes are also on an accompanying CD), making this book useful even to a novice programmer"--

Download or read book Diffractive Optics written by Donald C. O'Shea and published by SPIE Press. This book was released on 2004 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the reader with the broad range of materials that were discussed in a series of short courses presented at Georgia Tech on the design, fabrication, and testing of diffractive optical elements (DOEs). Although there are not long derivations or detailed methods for specific engineering calculations, the reader should be familiar and comfortable with basic computational techniques. This text is not a 'cookbook' for producing DOEs, but it should provide readers with sufficient information to assess whether this technology would benefit their work, and to understand the requirements for using the concepts and techniques presented by the authors.
Book Synopsis Diffractive Ethnography by : Jessica Smartt Gullion
Download or read book Diffractive Ethnography written by Jessica Smartt Gullion and published by Routledge. This book was released on 2018-04-30 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Across intellectual disciplines, the ontological turn is restructuring how we think about our relationships with the natural world. Influenced by the seemingly disparate realms of indigenous philosophy and quantum physics, the turn invites us to think about intra-actions and assemblages of human and nonhuman entities. This raises epistemological questions about how we know about the world, and spotlights some of the problems with how we currently do conventional social science research. Diffractive Ethnography invites social scientists to consider alternate methodologies that account for the complexity of human behavior situated in larger environmental contexts. For both novice and experienced researchers, this thought-provoking book opens new ways of thinking about methodology and raises questions about the ethical and justice orientations of our work.

This book was released on 2020-09-10 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis provides the necessary experimental and analytical tools to unambiguously observe the atomically resolved chemical reactions. A great challenge of modern science has been to directly observe atomic motions during structural transitions, and while this was first achieved through a major advance in electron source brightness, the information content was still limited and new methods for image reconstruction using femtosecond electron diffraction methods were needed. One particular challenge lay in reconciling the innumerable possible nuclear configurations with the observation of chemical reaction mechanisms that reproducibly give the same kind of chemistry for large classes of molecules. The author shows that there is a simple solution that occurs during barrier crossing in which the highly anharmonic potential at that point in nuclear rearrangements couples high- and low-frequency vibrational modes to give highly localized nuclear motions, reducing hundreds of potential degrees of freedom to just a few key modes. Specific examples are given in this thesis, including two photoinduced phase transitions in an organic system, a ring closure reaction, and two direct observations of nuclear reorganization driven by spin transitions. The emerging field of structural dynamics promises to change the way we think about the physics of chemistry and this thesis provides tools to make it happen.
Book Synopsis Diffraction-Limited Imaging with Very Large Telescopes by : D.M. Alloin
Download or read book Diffraction-Limited Imaging with Very Large Telescopes written by D.M. Alloin and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: A few years ago, a real break-through happened in observational astronomy: the un derstanding of the effect of atmospheric turbulence on the structure of stellar images, and of ways to overcome this dramatic degradation. This opened a route to diffraction-limited observations with large telescopes in the optical domain. Soon, the first applications of this new technique led to some outstanding astrophysical results, both at visible and infrared wavelengths. Yet, the potential of interferometric observations is not fully foreseeable as the first long-baseline arrays of large optical telescopes are being built or cOIIllnissioned right now. In this respect a comparison with the evolution of radio-astronomy is tempting. From a situation where, in spite of the construction of giant antennas, low angular resolution was prevailing, the introduction of long baseline and very long baseline interferometry and the rapid mastering of sophisticated image reconstruction techniques, have brought on a nearly routine basis high dynamic range images with milliarcseconds resolution. This, of course, has completely changed our views of the radio sky.

This book was released on 2021-02-28 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This exciting new resource presents a comprehensive introduction to the fundamentals of diffraction of two-dimensional canonical structures, including wedge, strip, and triangular cylinder with different boundary conditions. Maxwell equations are discussed, along with wave equation and scattered, diffracted and fringe fields. Geometric optics, as well as the geometric theory of diffraction are explained. With MATLAB scripts included for several well-known electromagnetic diffraction problems, this book discusses diffraction fundamentals of two-dimensional structures with different boundary conditions and analytical numerical methods that are used to show diffraction. The book introduces fundamental concepts of electromagnetic problems, identities, and definitions for diffraction modeling. Basic coordinate systems, boundary conditions, wave equation, and Green’s function problem are given. The scattered fields, diffracted fields, and fringe fields, radar cross section for diffraction modeling are presented. Behaviors of electromagnetic waves around the two-dimensional canonical wedge and canonical strip are also explored. Diffraction of trilateral cylinders and wedges with rounded edges is investigated as well as double tip diffraction using Finite Difference Time Domain and Method of Moments. A MATLAB based virtual tool, developed with graphical user interface (GUI), for the visualization of both fringe currents and fringe waves is included, using numerical FDTD and MoM algorithm and High-Frequency Asymptotics approaches.

Book Synopsis Diffractive Optics and Nanophotonics by : Igor Minin
Download or read book Diffractive Optics and Nanophotonics written by Igor Minin and published by Springer. This book was released on 2015-10-29 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book the authors present several examples of techniques used to overcome the Abby diffraction limit using flat and 3D diffractive optical elements, photonic crystal lenses, photonic jets, and surface plasmon diffractive optics. The structures discussed can be used in the microwave and THz range and also as scaled models for optical frequencies. Such nano-optical microlenses can be integrated, for example, into existing semiconductor heterostructure platforms for next-generation optoelectronic applications. Chapter 1 considers flat diffractive lenses and innovative 3D radiating structures including a conical millimeter-wave Fresnel zone plate (FZP) lens proposed for subwavelength focusing. In chapter 2 the subwavelength focusing properties of diffractive photonic crystal lenses are considered and it is shown that at least three different types of photonic crystal lens are possible. With the aim of achieving subwavelength focusing, in chapter 3 an alternative mechanism to produce photonic jets at Terahertz frequencies (terajets) using 3D dielectric particles of arbitrary size (cuboids) is considered. A scheme to create a 2D “teraknife” using dielectric rods is also discussed. In the final chapter the successful adaptation of free-space 3D binary phase-reversal conical FZPs for operation on surface plasmon-polariton (SPP) waves demonstrates that analogues of Fourier diffractive components can be developed for in-plane SPP 3D optics. Review ing theory, modelling and experiment, this book will be a valuable resource for students and researchers working on nanophotonics and sub-wavelength focusing and imaging.

Available in PDF, EPUB and Kindle. Book excerpt: Putting the New Materialist figure of diffraction to use in a set of readings – in which cultural texts are materially read against their contents and their themes, against their readers or against other texts – this volume proposes a criticalintervention into the practice of reading itself. In this book, reading and reading methodology are probed for their materiality and re-considered as being inevitably suspended between, or diffracted with, both matter and discourse. The history of literary and cultural reading, including poststructuralism and critical theory, is revisited in a new light and opened-up for a future in which the world and reading are no longer regarded as conveniently separate spheres, but recognized as deeply entangled and intertwined. Diffractive Reading ultimately represents a new reading of reading itself: firstly by critiquing the distanced perspective of critical paradigms such as translation and intertextuality, in which texts encountered, processed or otherwise subdued; secondly, showing how all literary and cultural readings represent different ‘agential cuts’ in the world-text-reader constellation, which is always both discursive and material; and thirdly, the volume materializes, dynamizes and politicizes the activity of reading by drawing attention to reading’s intervention in, and (co)creation of, the world in which we live.
