We study a novel type of optical nanoantennas made of high-permittivity low-loss dielectric particles. In addition to the electric resonances, the dielectric particles exhibit very strong magnetic resonances at the nanoscale. As result, single dielectric nanoparticle can have the properties of a Huygens element in the optical wavelength range. A highly efficient Yagi-Uda nanoantenna based on dielectric nano-particles is studied analytically, numerically and experimentally. Optical nanoantennas allow for enhancing and manipulating light on the scale much smaller than wavelength of light. Based on this ability, optical nanoantennas offer unique opportunities regarding key applications such as optical communications, photovoltaics, non-classical light emission, and sensing.
