In recent decades, there has been a phenomenal growth in the field of photonic crystal research and has emerged as an interdisciplinary area. Photonic crystals are usually nanostructured electromagnetic media consisting of periodic variation of dielectric constant, which prohibit certain electromagnetic wave frequency ranges called photonic bandgaps to propagate through them. Photonic crystals elicited numerous interesting features by unprecedented control of light and their exploitation is a promising tool in nanophotonics and designing optical components. The book ‘Advances in Photonic Crystals and Devices'is designed with 15 chapters with introductory as well as research and application based contents. It covers the following highlighted features: Basics of photonic crystals and photonic crystal fibers Different theoretical as well as experimental approaches Current research advances from around the globe Nonlinear optics and super-continuum generation in photonic crystal fibers Magnetized cold plasma photonic crystals Liquid crystal defect embedded with graphene layers Biophysics and biomedical applications as optical sensors Two-dimensional photonic crystal demultiplexer Optical logic gates using photonic crystals A large number of references The goal of this book is to draw the background in understanding, fabrication and characterization of photonic crystals using a variety of materials and their applications in design of several optical devices. Though the book is useful as a reference for the researchers working in the area of photonics, optical computing and fabrication of nanophotonic devices, it is intended for the beginners like students pursuing their masters'degree in photonics.

This book examines the application of nanoscience and nanotechnology in military defence strategies. Both historical and current perspectives on military technologies are discussed. The book provides comprehensive details on current trends in the application of nanotechnology to ground, air, and naval specializations. Furthermore, nanotechnology-enabled high energy explosives and propellants, chemical, biological, radiation, and nuclear threats and their detection/protection, and camouflage and stealth for signature management of military targets in multispectral wavelength signals are analyzed. The book also covers nanotechnology-enabled armor and platforms, which may serve as lightweight and high mechanical strength options in contrast to conventional systems. Finally, the book also emphasizes future military applications of nanotechnology and its integration into ‘smart'materials.Provides comprehensive details on trends in the application of nanotechnology to ground, air, and naval defence systems;Examines the application of nanoscience and nanotechnology in military defence strategies;Offers pathways and research avenues for development of nanotechnology and materials applications in military capacities.

This completely revised second edition of our hugely popular book invites the reader to explore ten of the most important areas of modern physics: Symmetry, Lasers, Superconductivity, Bose-Einstein Condensation, Nanoscience, Quantum Computation, Chaos and Fractals, Stellar Evolution, Particles, and Cosmology.The new edition adds three new chapters in about a third of the book, covering the latest, hottest topics in contemporary physics: Bose-Einstein Condensate: Where Many Become One and How to Get There: Bose Statistics: Counting of the Indistinguishables; Bose-Einstein Condensation (BEC): The Over-Population Crisis; Cooling and Trapping of Atoms: Towards BEC; Doppler Limit and its Break Down; Trapping of Cold Atoms: Magnetic and Magneto-Optic Trap; Evaporative Cooling; BEC Finally: But How do We Know?; BEC: What Good is it? Exploring Nanostructures: Towards the Bottom; The Rise of Nanoscience; Confined Systems; Quantum Devices; The Genius of Carbon; Spintronics; Nanos at Large. Quantum Computation and Information: Classical Computer; Quantum Computer; Quantum Gates; Deutsch's Algorithm; Finding the Period of a Function; Shor's Factorization Algorithm; Grover's Search Algorithm; Hardware and Error Correction; Cryptography; Quantum Teleportation.The authors give a fascinating, up-to-date account of the exciting advances in these fast-moving fields. Their emphasis is as much on describing natural phenomena as on attempting to explain them in terms of basic principles, replacing equations with physical insight. General readers and university undergraduates alike will find this unique book a useful guide to the worlds of modern physics, while the mature scientist will get an insightful survey of neighboring fields of research. For the teacher who takes a thematic approach to teaching physics, this book will be a complete source of current topics at the frontiers of research; and for the student, a valuable tool of study, made even more useful by numerous pertinent problems (with complete solutions) and references found at the end of each chapter.

In recent years, the exhilarating sense of discovery in the realm of physics has almost become the exclusive right of the specialist in the field. Books on contemporary physics tend to be oversimplified or too technical for the general reader to gain a proper appreciation of the appeal that this scientific quest holds for the modern-day physicist.Invitation To Contemporary Physics, however, offers a unique opportunity for the layman or new student to share in the fascination and excitement of seven of the most enthralling areas at the research frontiers of modern day physics: lasers, superconductivity, symmetries, chaos, the evolution of stars, elementary particles and cosmology.Organized into independent chapters, the book allows the reader to delve into each topic separately. Each chapter is also designed to commence at an elementary level, thus requiring little prior background knowledge from the reader. It is then developed in stages of increasing difficulty, but in such a way that any keen and determined reader will be able to comprehend. Emphasis is placed on understanding the basic principles behind the facts and ideas.The excitement and fascination in the intellectual pursuit of present-day physics is far too compelling to be left solely to the experts. The authors in this Invitation To Contemporary Physics have therefore answered the challenge of bringing it all home to the general reader. This book serves as a captivating introduction to modern-day physics for the layman, and is also an ideal reference text for a university course aiming at a general survey of contemporary physics.
