Rendering things invisible has turned out to be in the domain of science, not magic. The authors offer an approach to cloaking based on a simple conformal surface wrapped around the object of interest. Their theory shows that by covering the object with a stealth surface on the illuminated side, and a time-reversed version of the same surface on the shadowed side, one can realize ideal cloaking, independent of the size of the object, in a robust, broadband, ultrathin, and lossless technology.
