We numerically study optical properties of dimer metal-dielectric nanostructure representing the couple sphere-gap-cone nanoantenna separated by subwavelength gap. Numerical simulations demonstrate that the dimer exhibits magnetic and electric dipole resonances in the visible, strong field enhancement in the gap at the magnetic resonance as well as unidirectional scattering.
