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 sub‐ stantially 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. (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
