A new class of optical nanoantennas based on dielectric nanoparticles has been proposed and their main characteristics have been analyzed. It has been shown that one dielectric nanoparticle can have the properties of a Huygens element in the optical wavelength range. A Yagi-Uda nanoantenna based on dielectric nano-particles has been studied analytically and numerically.
Krasnok et al. (2011) studied this question.
