Query: Hybrid Nanophotonics   Advances in the field of plasmonics, that is, nanophotonics based on optical
properties of metal nanostructures, paved the way for the development of
ultrasensitive biological sensors and other devices whose operating principles
are based on localization of an electromagnetic field at the nanometer scale.
However, high dissipative losses of metal nanostructures limit their
performance in many modern areas, including metasurfaces, metamaterials, and
optical interconnections, which required the development of new devices that
combine them with high refractive index dielectric nanoparticles. Resulting
metal-dielectric (hybrid) nanostructures demonstrated many superior properties
from the point of view of practical application, including moderate dissipative
losses, resonant optical magnetic response, strong nonlinear optical
properties, which made the development in this field the vanguard of the modern
light science. This review is devoted to the current state of theoretical and
experimental studies of hybrid metal-dielectric nanoantennas and nanostructures
based on them, capable of selective scattering light waves, amplifying and
transmitting optical signals in the desired direction, controlling the
propagation of such signals, and generating optical harmonics.
