Double shell metamaterial coating for plasmonic cloaking
We study a doubleshell 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 epsilonnearzero material can suppress subtantially the scattering from a sphere and at the same time shield its interiors. The doublelayer coating allows to cloak different objects with various material and geometrical parameters.
