Perfect invisibility with nested inside-out cloaks

Popis výsledku v původním jazyce

In this paper, we present a new treatment of cloaking strategies proposed by Bělín et. al.,1 in their work on Ideal-lens Cloaks. By calculating material properties we design a metamaterial structure that acts as an invisibility cloak, based on the principle of an Abyss Cloak, which is a device that shifts the image of the cloaked object to the exterior position. The use of this approach comes with a better affinity for experimental realization. To support this claim, we execute a simple experiment, using a setup consisting of four optical wedges. Our work significantly stretches the arsenal of transformation optics devices, as the presented devices can be employed not only as invisibility cloaks, but also as building blocks for other devices, e.g. optical analogues of celestial mechanics.
