This book discusses the development of Fano-based techniques and reveals the characteristic properties of various wave processes by studying interference phenomena. It explains that the interaction of discrete (localized) states with a continuum of propagation modes leads to Fano interference effects in transmission, and explores novel coherent effects such as bound states in the continuum accompanied by collapse of Fano resonance. Originating in atomic physics, Fano resonances have become one of the most appealing phenomena of wave scattering in optics, microwaves, and terahertz techniques. The generation of extremely strong and confined fields at a deep subwavelength scale, far beyond the diffraction limit, plays a central role in modern plasmonics, magnonics, and in photonic and metamaterial structures. Fano resonance effects take advantage of the coupling of these bound states with a continuum of radiative electromagnetic waves. With their unique physical properties and unusual combination of classical and quantum structures, Fano resonances have an application potential in a wide range of fields, from telecommunication to ultrasensitive biosensing, medical instrumentation and data storage. Including contributions by international experts and covering the essential aspects of Fano-resonance effects, including theory, modeling and design, proven and potential applications in practical devices, fabrication, characterization and measurement, this book enables readers to acquire the multifaceted understanding required for these multidisciplinary challenges.

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.
