摘要: Surface plasmons (SPs) are electromagnetic excitations existing at the interface between a metal and dielectric material. Control manipulation of light based on SPs nanometer scale offers significant advantages in nanophotonic devices with very small elements, since peculiar properties can be tailored by construction nanostructures various interfaces metals materials. Recent progress for is reviewed. Resonance frequencies or wavelengths tuned design nanostructures, such as nanoparticles, nanorods, nanowires, nanosheets, nanodisks. Moreover, SP resonance modes also control shapes sizes where include longitudinal transversal resonances, dipolar multipolar Fano resonances. Based coupling metal–semiconductor metal–dielectric metal–polymer propagating guiding achieved through hybrid structures. Additionally, exhibit remarkable field enhancement effects (e.g., local near-field enhancement, optical transmission enhancement) due to coupling. Furthermore, perform unique focusing imaging characteristics beyond diffraction limit. Tailoring expected used development high-performance components circuits, which offer both potential challenges new generations devices.
