Abstract

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_{\rm sca}∼1/λ⁴ for small values of size parameter, but could be wavelength independent Q_{\rm sca}∼ const, or even increase with the wavelength as Q_{\rm sca}∼λ². 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 analogues of Brewster's angles for spheres.
