Abstract

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)
