All-Dielectric Nanophotonics

Book excerpt: All-Dielectric Nanophotonics aims to review the underlying principles, advances and future directions of research in the field. The book reviews progress in all-dielectric metasurfaces and nanoantennas, new types of excitations, such as magnetic and toroidal modes and associated anapole states. Ultrahigh-Q resonant modes such as bound states in the continuum are covered and the promise of replacing conventional bulky optical elements with nanometer-scale structures with enhanced functionality is discussed. This book is suitable for new entrants to the field as an overview of this research area. Experienced researchers and professionals in the field may also find this book suitable as a reference. - Provides an overview of the fundamental principles, theories and calculation techniques underpinning all-dielectric nanophotonics research - Reviews current progress in the field, such as all-dielectric metasurfaces and nanoantennas, new types of excitations, associated anapole states, and more - Discusses emerging applications such as active nanophotonics with in-depth analysis
