Considered a major field of photonics, plasmonics offers the potential to confine and guide light below the diffraction limit and promises a new generation of highly miniaturized photonic devices. This book combines a comprehensive introduction with an extensive overview of the current state of the art. Coverage includes plasmon waveguides, cavities for field-enhancement, nonlinear processes and the emerging field of active plasmonics studying interactions of surface plasmons with active media.

Metals contain a sea of free electrons that are easily driven into collective oscillation by electromagnetic waves. As a result, small metal objects can serve as antennas that strongly scatter light. At the same time, extended metal surfaces have been shown to guide surface plasmons (photons bound to surface charge oscillations) that can confine light to deep sub-wavelength dimensions. Patterned metallic films can combine both the scattering and guiding properties of metals to capture and concentrate light from free space into a photodetector or to control the emission of light from emitting media. We first consider the wide range of functions that can be achieved in directing light emission with the help of smooth metallic films. We then describe how light interacts with patterned metallic films and present a detailed study of the effect of a single metallic groove on the scattering and surface plasmon guiding processes. This has lead to our discovery of new, exciting opportunities for dense optical functionality with non-periodically patterned metallic films. We show that a micronscale structure consisting of just two grooves in a metal film can lead to directional light coupling and wavelength splitting with a contrast ratio of 3:1. Our understanding is then generalized giving rise to a fast, simplified optimization of large non-periodic structures for a desired function. Lastly we consider the efficiency and bandwidth limits of coupling light through sub-wavelength slits for photodetection. We outline a path to efficient, spectrally selective detection which may find application in compact, polarization sensitive, multi-wavelength plasmonic detectors.

Plasmonics gives researchers in universities and industries and designers an overview of phenomena enabled by artificially designed metamaterials and their application for plasmonic devices. The purpose of this book is to provide a detailed introduction to the basic modeling approaches and an overview of enabled innovative phenomena. The main research agenda of this book is aimed at the study of modeling techniques and novel functionalities such as plasmonic enhancement of solar cell efficiency, plasmonics in sensing, etc. The topics addressed in this book cover the major strands: theory, modeling and design, applications in practical devices, fabrication, characterization, and measurement. It is worthwhile mentioning that the strategic objectives of developing new artificial functional materials require close cooperation of the research in each subarea.

This book, edited by two of the most respected researchers in plasmonics, gives an overview of the current state in plasmonics and plasmonic-based metamaterials, with an emphasis on active functionalities and an eye to future developments.

Plasmonics is entering the curriculum of many universities, either as a stand alone subject, or as part of some course or courses. Nanotechnology institutes have been, and are being, established in universities, in which plasmonics is a significant topic of research. Modern Plasmonics offers a comprehensive presentation of the properties of surface plasmon polaritons, in systems of different structures and various natures, e.g. active, nonlinear, graded, theoretical/computational and experimental techniques for studying them, and their use in a variety of applications. Contains material not found in existing books on plasmonics, including basic properties of these surface waves, theoretical/computational and experimental approaches, and new applications of them Each chapter is written by an expert in the subject to which it is devoted Emphasis on applications of plasmonics that have been realized, not just predicted or proposed

Plasmonics and metamaterials are growing fields that consistently produce new technologies for controlling electromagnetic waves. Many important advances in both fundamental knowledge and practical applications have been achieved in conjunction with a wide range of materials, structures and wavelengths, from the ultraviolet to the microwave regions of the spectrum. In addition to this remarkable progress across many different fields, much of this research shares many of the same underlying principles, and therefore, significant synergy is expected. This Special Issue introduces the recent advances in plasmonics and metamaterials and discusses various applications, while addressing a wide range of topics, in order to explore the new horizons emerging for such research.

This contributed volume summarizes recent theoretical developments in plasmonics and its applications in physics, chemistry, materials science, engineering, and medicine. It focuses on recent advances in several major areas of plasmonics including plasmon-enhanced spectroscopies, light scattering, many-body effects, nonlinear optics, and ultrafast dynamics. The theoretical and computational methods used in these investigations include electromagnetic calculations, density functional theory calculations, and nonequilibrium electron dynamics calculations. The book presents a comprehensive overview of these methods as well as their applications to various current problems of interest.
