We study a double-shell cloak for hiding objects with the dimensions comparable with the radiation wavelength. We demonstrate that the structure consisting of a dielectric layer and a layer of an epsilon-near-zero material can suppress substantially the scattering from a sphere and at the same time shield its interiors. The double-layer coating allows to cloak different objects with various material and geometrical parameters. (C) 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
