Effective control over single atom emission might lead to major breakthrough in the field of nanotechnology. It is believed that use of hyperbolic metamaterials (HMM) can be helpful. COMSOL Multiphysics® was used to model interaction of electric dipole with effective HMM and calculate emission rate of dipole in comparison to that value in the absence of metamaterial. Dielectric nanoantennas of certain shape were then placed on the surface of HMM to provide narrow directivity pattern of the emitted light. Parameters were found with COMSOL Multiphysics® Optimization Module. Modeling results were accurate compared to analytical ones. A regime was found when radiative rate of dipole, placed near HMM slab with nanoantennas, is almost 10 times higher than that of dipole in vacuum.
