Abstract

We present a new design of an invisibility cloak, built of two rings of transparent holograms. The proposed device is based on the principle of an Abyss Cloak, which shifts the image of the cloaked object to the exterior position. Our device operates for a visible light and for all azimuthal positions around the device. Preliminary numerical simulations suggest extremely simple material properties for the included holograms, which makes our device very likely to be realised experimentally. To the best of our knowledge, our work presents the first invisibility cloak, operating in a visible range of light and for a wide range of viewing directions, and thus makes a significant contribution to the arsenal of transformation optics devices.
