Shifting media for carpet cloaks, antiobject independent illusion optics, and a restoring device

In traditional cases, the basic principle of carpet cloak is that a two-dimensional bump above ground plane is compressed into a one-dimensional line which is close to the ground plane. As a result, the bump can be hidden. In this paper, different from the traditional carpet cloak, we propose a shifting media to achieve the carpet cloak. By covering with the shifting media, an object floating on a ground plane can be directly shifted beneath the ground plane (rather than compressing it into a line), resulting in a floating carpet cloak. Antiobject independent illusion optics, i.e., turning an object into another one without any antiobjects, can be realized based on this kind of shifting media. As an application of the shifting media, a restoring device, by which the broken objects (such as antiques) can be perfectly restored, is also investigated.
