Plasmonic resonators, composed of metallic micro- and nanostructures, belong to the category of excited-state physics on resonances from gigahertz to petahertz. Dynamical physics is in contrast to ground-state physics that includes, in a wide sense, thermal states, and is in connection to diverse applications to enhance existing photoinduced effects and phenomena such as plasmon-enhanced photoluminescence and Raman scattering. This book has three main aims:
(1) To provide fundamental knowledge about plasmonic resonators
(2) To explain diverse plasmonic resonators
(3) To stimulate further development in plasmonic resonators
Plasmon-related studies, sometimes called plasmonics and including a substantial portion of metamaterials, have significantly developed since the 1980s. The results are numerous and too many to study from the beginning. This book summarizes the results, including the history (past), all the possible types of plasmonic resonators (present), and the wide range of applications (future). Thus, this book will benefit a wide range of readers interested in nanotechnology involving metallic nanostructures, from undergraduate and graduate students to active researchers, even nonexperts, in nanotechnology-based physics, chemistry, engineering, and biotechnology, because it provides the basics of plasmons and resonant physics, systematic knowledge about plasmonic resonators, and cutting-edge and in-depth information on plasmon enhancement studies. The author intends this book to help readers contribute to diverse applications of plasmonic resonators in the near future.
