Hiding under the carpet: a new strategy for cloaking

Phys Rev Lett. 2008 Nov 14;101(20):203901. doi: 10.1103/PhysRevLett.101.203901. Epub 2008 Nov 10.


A new type of cloak is discussed: one that gives all cloaked objects the appearance of a flat conducting sheet. It has the advantage that none of the parameters of the cloak is singular and can in fact be made isotropic. It makes broadband cloaking in the optical frequencies one step closer.
