This book is built on the recent advancements in understanding thermoplasmonics and highlights the exciting new directions that are shaping this field. Thermoplasmonics using light to heat nanostructures is a promising and rapidly expanding subfield of plasmonics. When the light frequency matches the oscillation frequency of free electrons on the nanostructures, it induces a collective oscillation known as plasmon resonance. This effect allows fantastic control over the optical field at sub-wavelength scales, enhancing the light-matter interaction to surmount the diffraction limits. The plasmon resonance is responsible for fascinating and tunable properties, such as local field enhancement, generation of hot electrons as well as the localized/collective heating. These energetic carriers and heat can be harvested to drive a wide range of physical and chemical processes, making them promising for different fields of science. In this book, we discuss the recent advances in understanding of thermoplasmonics and highlight some of the exciting new directions, covering aspects of its principles, materials, and characterization, along with the diverse applications. The basic fundamentals are first introduced from plasmonic theory and thermodynamics to the thermal-induced processes. Then, much effort is placed on examination of thermoplasmonic materials and the common synthesis methods. The strategies for proper material selection and rational structural design are summarized toward more efficient energy conversion. The synthesizing methods for novel nanostructures are presented with a goal to achieve optimal thermoplasmonic properties. Afterward, the characterization technologies for thermoplasmonics are also addressed, which involves analytic and computational approaches as well as nanoscale thermometry. For each application, the unique role of thermoplasmonics and their associated benefits are elaborated. Research trends and insights into the use of thermoplasmonics to improve performance are analyzed as well. Finally, the current challenges and future perspectives in this field are pointed out in this book.

The linear and nonlinear resonance behaviour of optical antennas (metallic nanostructures showing resonance behaviour at optical frequencies) made of gold and aluminum using electron-beam lithography is investigated. Specifically, it is of interest how the emission behaviour is changed by the coupling of two antenna arms via a small gap. Experimental techniques applied include dark-field spectroscopy and two-photon luminescence.

This book covers electrostatic properties of hyperbolic metamaterials (HMMs), a fascinating class of metamaterials which combine dielectric and metal components. Due to the hyperbolic topology of the isofrequency surface in HMMs, the so-called resonance cone direction exists, and as a result, propagation of quasi-electrostatic waves, or more commonly, electrostatic waves close to the resonance cone with large wave vectors, is possible. However, the investigation of electrostatic wave properties in HMMs is largely overlooked in most works on the subject, and the purpose of this monograph is to fill this gap. This book gives a thorough theoretical treatment of propagation, reflection, and refraction of electrostatic waves in HMMs of various dimensions and geometries. It will be of interest to students and researchers who work on electrical and optical properties of metamaterials.

This book presents a quantum framework for understanding inelastic light scattering which is consistent with the classical descriptions of Raman phenomena and Rayleigh scattering, thus creating a unified theoretical picture of light scattering. The Raman effect was discovered in 1928 and has since proved to be one of the most powerful tools to study the molecular structure of gases, liquids, and crystals. The subsequent development of new scientific disciplines such as nonlinear optics, quantum optics, plasmonics, metamaterials, and the theory of open quantum systems has changed our views on the nature of Rayleigh and Raman scattering. Today, there are many excellent books on the theory and applications of light scattering, but a consistent description of light scattering from a unified viewpoint is missing. The authors’ approach has the power to re-derive the results of both classical and quantum approaches while also addressing many questions that are scattered across the research literature: Why is Rayleigh scattering coherent while Raman scattering is not, although both phenomena are caused by the incidence of a coherent wave? Why are coherent Stokes and coherent anti-Stokes Raman scattering caused by two coherent incident waves both always coherent? This book answers these questions and more, and explains state-of-the-art experimental results with a first-principles approach that avoids phenomenological arguments. Many of the results presented are appearing in book form for the first time, making this book especially useful for young researchers entering the field. The book reviews basic concepts of quantum mechanics and quantum optics and comes equipped with problems and solutions to develop understanding of the key mathematical techniques. The rigorous approach presented in the book is elegant and readily grasped, and will therefore prove useful to both theorists and experimentalists at the graduate level and above, as well as engineers who use Raman scattering methods in their work.
