In this paper we suggest and study a metamaterial composed of non-magnetic spherical particles, which according to both approximate analytical theory and exact simulations possesses an isotropic negative refractive index in the near-infrared frequency range. The effect of negative refraction has been confirmed by full-wave simulations of the Gaussian beam diverted by a metamaterial prism. The disagreement between predictions of the theory for an infinite lattice and the results of full-wave simulations for the prism is discussed.
