Optical Methods of Engineering Analysis (original) (raw)

Sergey Y. Yurish Editor. Advances in Optics: Reviews Book Series, Volume 3., 2018

Preface It is my great pleasure to introduce the third volume of new Book Series ‘Advances in Optics: Reviews’ started by the IFSA Publishing in 2018. Three volumes were published in this year. The ‘Advances in Optics: Reviews’ Book Series is published as an Open Access Books in order to significantly increase the reach and impact of these volumes, which also published in two formats: electronic (pdf) with full-color illustrations and print (paperback). The third of three volumes of this Book Series has organized by topics of high interest. In order to offer a fast and easy reading of each topic, every chapter in this book is independent and self-contained. All chapters have the same structure: first an introduction to specific topic under study; second particular field description including sensing or/and measuring applications. Each of chapter is ending by complete list of carefully selected references with books, journals, conference proceedings and web sites. The Vol.3 is devoted to various topics of applied optics and contains 17 chapters written by 49 experts in the field from 14 countries: Australia, China, India, Israel, Italy, Japan, Malaysia, Mexico, The Netherlands, Poland, Taiwan, UK, USA and Vietnam. ‘Advances in Optics: Reviews’ Book Series is a comprehensive study of the field of optics, which provides readers with the most up-to-date coverage of optics, photonics and lasers with a good balance of practical and theoretical aspects. Directed towards both physicists and engineers this Book Series is also suitable for audiences focusing on applications of optics. A clear comprehensive presentation makes these books work well as both a teaching resources and a reference books. The book is intended for researchers and scientists in physics and optics, in academia and industry, as well as postgraduate students. I shall gratefully receive any advices, comments, suggestions and notes from readers to make the next volumes of ‘Advances in Optics: Reviews’ Book Series very interesting and useful. Dr. Sergey Y. Yurish Editor IFSA Publishing Barcelona, Spain.

Advances in Optics Reviews. Vol. 5

Advances in Optics Reviews. Vol. 5, 2021

It is my great pleasure to introduce the fifth volume from our popular open access Book Series ‘Advances in Optics: Reviews’ started by the IFSA Publishing in 2018. The Vol. 5 of this Book Series is also published as an Open Access Book in order to significantly increase the reach and impact of this volume, which also published in two formats: electronic (pdf) with full-color illustrations and print (paperback). ‘Advances in Optics: Reviews’ Book Series is a comprehensive study of the field of optics, which provides readers with the most up-to-date coverage of optics, photonics and lasers with a good balance of practical and theoretical aspects. Directed towards both physicists and engineers this Book Series is also suitable for audiences focusing on applications of optics. A clear comprehensive presentation makes these books work well as both a teaching resources and a reference books. The book is intended for researchers and scientists in physics and optics, in academia and industry, as well as postgraduate students. Like the first four volumes of this Book Series, the fifth volume also has been organized by topics of high interest to offer a fast and easy reading of each topic, every chapter in this book is independent and self-contained. All chapters have the same structure: first an introduction to specific topic under study; second particular field description including sensing or/and measuring applications. Each of chapter is ending by well selected list of references with books, journals, conference proceedings and web sites. The fifth volume is devoted to optics, lasers, optical communication and networks, and written by 53 authors from academia and industry from 12 countries: Belgium, Bulgaria, China, France, Italy, Iraq, Japan, Russia, Spain, Turkey, USA and Vietnam. But it is not a simple set of reviews. As usually, each chapter contains the extended state-of-the-art followed by new, unpublished before, obtained by the authors results. This book ensures that our readers will stay at the cutting edge of the field and get the right and effective start point and road map for the further researches and developments. By this way, they will be able to save more time for productive research activity and eliminate routine work. I shall gratefully receive any advices, comments, suggestions and notes from readers to make the next volumes of ‘Advances in Optics: Reviews’ Book Series very interesting and useful. Dr. Sergey Y.

Gratings: Theory and Numeric Applications, Second Revisited Edition

One and a half year ago we have assembled the online edition of our e-book devoted to the theory of diffraction grating. More than a thousand downloads have been registered since then, and I sincerely hope that the detailed description that we tried to present in the book would be useful to the scientific community. There is no substantial advance in the grating theory during the last 18 months. However, due to time constraints, in the first edition we were not able to include some important developments that have been advanced before. This is the main reason to propose a Second Edition of "Gratings: Theory and Numeric Applications," that contains two more chapters and supplements to other four chapters. Here is the summary of the changes that are made: ii Gratings: Theory and Numeric Applications, 2012 metallic gratings in TM (p, or S) polarization. And quite ironically, the improvement came from advances in the competing RCW approach. These methods are relatively easy for programing nowadays, after solving the numerical problems due to growing exponentials and factorization rules of the product of permittivity and electric field, however there are still some persisting problems for highly conduction metals. In addition, neither the differential, nor the Fourier modal methods can deal with infinitely conducting gratings. Several methods are quite flexible concerning the geometry of the diffracting objects and the grating material. For example, the integral method can treat inverted profiles, rod gratings with arbitrary cross section, finitely or infinitely conducting materials in any polarization, but its programming require deep mathematical understanding of the singularities and integrability of the Green's functions. Other two flexible methods are quite famous and widely used, even in the form of commercially available codes. These are the finite-element method, and the finite-difference time domain method. The flexibility with respect to the geometrical structure, optical index inhomogeneity and anisotropy, etc. has to be paid by the necessity of sophisticated meshing algorithms and very large sparse matrix manipulations. These few examples represent only the top of the iceberg, and are invoked to illustrate the basic idea that the best method has not been invented, yet. Probably never. We have tried to gather a team of specialists in rigorous theories of gratings in order to cover as large variety of methods and applications as practically possible. The last such effort dates quite long ago, and it has resulted in the famous Electromagnetic Theory of Gratings (ed. R. Petit, Springer, 1980), a book that has long served the community of researchers and optical engineers, but that is now out of press and requires a lot of update and upgrade, something that we hope to achieve, at least partially with this new book. Our choice of electronic publishing is determined by the desire to ensure larger free access that is not easily available through printed editions. I want to thank all the contributors to this Edition. Special thanks are due to my colleagues Fréderic Forestier and Boris Gralak for the technical efforts to make the electronic publishing possible.

Advances in Optics: Reviews

𝜖𝜇𝜖 0 𝜇 0 , which 𝑣 is the wave speed for the wave equation (1.11). Then we get a standard electromagnetic wave equation as (1.12) Chapter 1. Physical Optics 25 This is a fundamental and starting formula for studying physical optics or wave optics in a linear, isotropic, and homogeneous dielectric medium. From the formula (1.11), we know that wave speed in the medium is In free space, the wave speed 𝑐 = 1 √𝜖0𝜇0 , which is just the light speed in vacuum. Based on this point, Maxwell thought of light as an electromagnetic wave. According to the definition of the index of refraction 𝑛 = 𝑐 𝑣 and the expression (1.13), such that we can get that the index of refraction of the medium is 𝑛 = √ 𝜖𝜇. In optics, it is generally valid that 𝜇 ≈ 1 (the reason is to be explained in Section 1.1.4), so that the index of refraction of the medium can be written 𝑛 = √𝜖.
