Abstract.  We theoretically demonstrate ultradirectional, azimuthally symmetric forward scattering by dielectric cylindrical nanoantennas for futuristic nanophotonic applications in visible and near-infrared regions. Electric and magnetic dipoles have been optically induced in the nanocylinders at the resonant wavelengths. The cylindrical dielectric nanoparticles exhibit complete suppression of backward scattering and improved forward scattering at first generalized Kerker’s condition. The influence of gap between nanocylinder elements on the scattering pattern of the homodimers has been demonstrated. Further, for highly directive applications, a linear chain of ultradirectional cylindrical nanoantenna array has been proposed.
