Advances in the field of plasmonics, i.e., nanophotonics exploiting the optical properties of metal nanostructures, paved the way for the development of ultrasensitive devices, including biological and other sensors, that rely on the nanoscale localization of an electromagnetic field for their operation. However, the high dissipation loss of metal nanostructures limit their use in many current applications, including metasurfaces, metamaterials, and nanowaveguides, thus requiring the development of new devices that combine metal nanostructures with highly refractive dielectric nanoparticles. The resulting metal-dielectric (hybrid) nanostructures have demonstrated many interesting properties from the practical application viewpoint (the moderate dissipation loss, resonant magnetooptical response, strong nonlinear optical properties, etc.), thus placing this field at the vanguard of the modern science of light. This paper reviews the current state of theoretical and experimental research into hybrid metal-dielectric nanoantennas and their derivative nanostructures capable of selectively scattering light waves, directionally amplifying and transmitting optical signals, controlling the propagation of such signals, and generating optical harmonics.
