We study light scattering by spheres made of negative refractive index materials. We demonstrate that scattering efficiency of the light does not always obey the well-known Rayleigh's law Q(sca)similar to kappa(4) for small values of size parameter kappa, but could be constant Q(sca)similar to const, or even inversionally proportional Q(sca) similar to 1/kappa(2). In addition, it is found that spheres with radius comparable with the input wavelength may exhibit suppression of the scattering in any directions, particularly, in forward one. It can be considered as analogs of Brewster's angles for spheres.
