Book SynopsisGets you quickly up to speed with the theoretical and practical aspects of free space optical systems engineering design and analysis One of today''s fastest growing system design and analysis disciplines is free space optical systems engineering for communications and remote sensing applications. It is concerned with creating a light signal with certain characteristics, how this signal is affected and changed by the medium it traverses, how these effects can be mitigated both pre- and post-detection, and if after detection, it can be differentiated from noise under a certain standard, e.g., receiver operating characteristic. Free space optical systems engineering is a complex process to design against and analyze. While there are several good introductory texts devoted to key aspects of opticssuch as lens design, lasers, detectors, fiber and free space, optical communications, and remote sensinguntil now, there were none offering comprehensive coverage of the basics nTable of ContentsPreface xii About the Companion Website xvi 1 Mathematical Preliminaries 1 1.1 Introduction 1 1.2 Linear Algebra 1 1.2.1

Book SynopsisThis book demonstrates how to design an optical system using Ansys Zemax OpticStudio, a full-featured optical design program. The complete design process from lens definition to tolerancing is developed and illustrated using the program. This text is not a user's manual for Zemax OpticStudio. Rather, it starts with a single lens to demonstrate the laws of geometrical optics and illustrate basic optical errors (aberrations) with the software.Through a series of examples and exercises, one can follow each step in the design process to analyze and optimize the system to meet the required performance specifications. The text is organized to help readers (1) reproduce each step of the process, including the plots for evaluating lens performance, and (2) understand the significance of these plots in constructing a final design.Table of Contents The Basics Rays and Ray Sketching How to Put a Lens in a Computer To First Order… Stop and Pupils and Windows, Oh My!

Book SynopsisNow in its second edition, this book has been thoroughly updated to provide a current overview of the theoretical and experimental concepts needed to understand and work in nano-optics. This is an invaluable reference for graduate students entering the field, as well as for researchers and course teachers.Trade Review'The reader will appreciate its scope and depth, as it covers topics ranging from resolution and microscopy to metamaterials and optical antennas. This book provides an integrated approach to the entire field, and the format breaks the material into accessible sub-units. The physical and mathematical rigor is high, and approximations and limitations of the theory and the experimental devices are clearly stated. The material is highly recommended for a graduate course.' Barry R. Masters, Optics and Photonics News'This text responds to the growing importance of nanoscience, and presents a rare collection of topics across optics and microscopy at the nanoscale. A major goal of nano-optics is to extend the use of optical techniques to length scales beyond the diffraction limit. Notably, the book features a valuable discussion of resolution, localization and position accuracy in microscopy. A non-exhaustive list of subjects covered in later chapters includes near- and far-field microscopy techniques, quantum emitters and surface plasmons in nanostructures.'

Book SynopsisThe behavior of light in small scale optics or nano/micro optical devices has shown promising results, which can be used for basic and applied research, especially in nanoelectronics. Small Scale Optics presents the use of optical nonlinear behaviors for spins, antennae, and whispering gallery modes within micro/nano devices and circuits, which can be used in many applications. This book proposes a new design for a small scale optical devicea microring resonator device. Most chapters are based on the proposed device, which uses a configuration know as a PANDA ring resonator. Analytical and numerical methods demonstrate that many applications can be exploited using this device, in particular when it is coated with metallic material.The book begins with the background and description of the PANDA ring resonator. The authors examine optical bistability in microring resonators and test the analytical results with those predicted by the OptiFDTD software package. They thenTable of ContentsNonlinear PANDA Ring.

Book SynopsisThe field of quantum optics has witnessed significant theoretical and experimental developments in recent years. This book provides an in-depth and wide-ranging introduction to the subject, emphasising throughout the basic principles and their applications. The book begins by developing the basic tools of quantum optics, and goes on to show the application of these tools in a variety of quantum optical systems, including lasing without inversion, squeezed states and atom optics. The final four chapters are devoted to a discussion of quantum optical tests of the foundations of quantum mechanics, and to particular aspects of measurement theory. Assuming only a background of standard quantum mechanics and electromagnetic theory, and containing many problems and references, this book will be invaluable to graduate students of quantum optics, as well as to researchers in this field.Table of Contents1.

Book SynopsisThis book is aimed at those readers who already have some knowledge of mathematical methods and have also been introduced to the basic ideas of quantum optics. It should be attractive to students who have already explored one of the more introductory texts such as Loudon''s The quantum theory of light (2/e, 1983, OUP) and are seeking to acquire the mathematical skills used in real problems. This book is not primarily about the physics of quantum optics but rather presents the mathematical methods widely used by workers in this field. There is no comparable book which covers either the range or the depth of mathematical techniques.Trade Review... the authors are well-known for their work on topics, such as the quantum-phase operator and quasi-probability distribution so theory PhD students will be able to learn these subjects direct from the horse's mouth. The authors have [] included, for pedagogic purposes, extra detail of the mathematical workings that a PhD student would not be able find in the research literature. * New Scientist, 6 June 1998 *The reader will find here a very clear presentation of material not readily found elsewhere. Postgraduate students of quantum optics will find this work to be of the greatest utility... Care has been taken to present quite difficult topics in the simplest and most straightforward way; and yet the treatment is concise and focused... Experienced researchers will find that this text is a most convenient handbook of techniques, and will want it close to their elbow. * Contemporary Physics, 1998, vol. 39, no. 4 *Table of Contents1.

Book SynopsisIn 2014, a 28-year old British doctor found himself co-running the Ebola isolation unit in Sierra Leone’s main hospital after the doctor in charge had been killed by the virus. Completely overwhelmed and wrapped in stifling protective suits, he and his team took it in turns to provide care to patients while removing dead bodies from the ward. Against all odds he battled to keep the hospital open, as the queue of sick and dying patients grew every day. Only a few miles down the road the Irish Ambassador and Head of Irish Aid worked relentlessly to rapidly scale up the international response. At a time when entire districts had been quarantined, she travelled around the country, and met with UN agencies, the President and senior ministers so as to be better placed in alerting the world to the catastrophe unfolding in front of her. In this blow-by-blow account, Walsh and Johnson expose the often shocking shortcomings of the humanitarian response to the outbreak, both locally and internationally, and call our attention to the immense courage of those who put their lives on the line every day to contain the disease. Theirs is the definitive account of the fight against an epidemic that shook the world.Trade ReviewGetting to Zero is a compelling read, full of compassion, grief, ingenuity and stories of courage and unstinting commitment of local nurses, cleaners and others who remain unsung heroes of Ebola. But it is also full of tales of denial, extraordinary lapses in leadership and awkward truths that will make uncomfortable reading for many, locally and internationally. * Guardian *Written in an honest and engaging tone, their experience behind the scenes of the outbreak is illuminating and highlights important lessons for the management of future outbreaks, and the operational errors that increased the number of lives lost in the west African outbreak of 2014–16. * Lancet *Hundreds of reports have been written on the 2014 epidemic – the most widespread Ebola outbreak since the virus was discovered – but none is nearly as insightful, compassionate or unsparing as this. * Irish Times *A brave, bold, yet humble account from the frontlines of the Ebola outbreak in Sierra Leone. This is vital reading to help us all do better next time. * David Miliband, President and CEO of the International Rescue Committee *Courage in extreme clinical danger, courage to challenge obstructive bureaucracy, courage to make tough decisions and the courage to endure. This is the courage that Sinead Walsh and Oliver Johnson displayed in Sierra Leone. Their compelling book is essential reading for all who care about global health. * Eldryd Parry, founder of the Tropical Health and Education Trust *A captivating and brutally honest account of the Ebola epidemic from two brave, committed individuals who unexpectedly found themselves at its epicentre. The authors pull no punches, and leave us asking: will these lessons be learned, or will the world once again forget and move on? * Jeremy Farrar, Director of the Wellcome Trust *This powerful book asks important questions about aid and development and offers insights that everyone working in global health should absorb – as well as being a personal and very moving account of an epidemic that killed thousands. * Lord Nigel Crisp, Co-Chair of the All Party Parliamentary Group on Global Health *Walsh and Johnson represent the best of international intervention. This book reveals the complexities and level of cooperation that made “getting to zero” possible. Offers excellent insight into those trying times. * O.B. Sisay, Director of the Situation Room at the National Ebola Response Centre, Sierra Leone *An extraordinary account from the thick of the battle against Ebola.

Book SynopsisIn 2007, a stranger-than-fiction multibillion-dollar bidding war for the Chicago Board of Trade (CBOT) erupted between the Chicago Mercantile Exchange (CME) and Atlanta's IntercontinentalExchange (ICE). Zero-Sum Game: The Rise of the World's Largest Derivatives Exchange takes readers behind the scenes of this battle to tell the grippingand often comicalstory of how the historic merger between CME and CBOT almost didn't happen. Author Erika S. Olson, a managing director at CBOT during the bidding war, delivers a blow-by-blow account of the fight for the world's oldest futures exchange, taking you inside CBOT's landmark Chicago Loop headquarters, onto the high-octane trading floor, and into executives' offices.

Book SynopsisThree experts in the field of thin-film optics present a detailed and self-contained theoretical study of planar multilayers and how they can be effectively exploited in both traditional and modern applications. Starting with a discussion of the relevant electromagnetic optics, the fundamental optical properties of multilayers are introduced using an electromagnetic approach based on a direct solving of Maxwell''s equations by Fourier transforms. This powerful approach is illustrated through the comprehensive description of two of the most important phenomena in multilayers, i.e. giant field enhancement in dielectric stacks and light scattering from thin-film optical filters. The same approach is extended to the description of the operation of planar microcavities and the balance of energy between radiated and trapped light. This book will be valuable to researchers, engineers and graduate students with interests in nanophotonics, optical telecommunications, observational astronomy andTrade Review'… clear and well-written explanations, and very enlightening discussions of TFC-from multilayer stacks to planar microcavities … it makes for rewarding reading, and I recommend it to all students of TFCs.'

Book Synopsis THE WALL STREET JOURNAL BESTSELLERRelationship teacher, coach, and founder of The Relationship School Jayson Gaddis reveals the origins of conflict styles, how to stop avoiding difficult conversations, and how to resolve conflict in our most important relationships. Conflicts in our closest relationships are scary because so much is at stake. If the conflict doesn't go well, we could lose our marriage, our family or our job, all connected to our security and survival. So we do just about anything not to lose those relationships, including avoid conflict, betraying ourselves or becoming dishonest. Unresolved conflict affects every single aspect of our lives, from self-confidence to physical and mental health. Jayson Gaddis is a personal trainer for relationships and one of the world’s leading authorities on interpersonal conflict. For almost two decades, Gaddis has helped individuals, couples, and teams get to the bottom of their deepest conflicts. He helps people see the wisdom in conflict and how to get to zero—which means we have successfully worked through our conflict and have nothing in the way of a good connection. In Getting to Zero, Gaddis shows the reader how to stop running away from uncomfortable conversations and instead learn how to work through them. Through funny personal stories, uncomfortable examples, and effective tools and skills, he shows the reader how to move from disconnection to connection, acceptance, and understanding. This method upgrades the old tired and static conflict resolution approaches and offers a fresh, street-level, user-friendly road map on exactly how to work through conflict with the people you care most about.
