Abstract
A cloaking device includes an object-side, an image-side and an apex axis extending from the object-side to the image-side. An object-side cloaking region (CR) planar reflection boundary having an outward facing mirror surface and an inward facing surface, and an image-side CR planar reflection boundary having an outward facing mirror surface and an inward facing surface, are included. A cloaking region is bounded by inward facing surfaces of the object-side CR planar reflection boundary and the image-side CR planar reflection boundary. At least one exterior curved reflection boundary with an inward facing mirror surface is spaced apart from the object-side CR planar reflection boundary and the image-side CR planar reflection boundary. A centrally positioned planar reflection boundary with an outward facing mirror surface is positioned between the objects-side and image-side CR planar reflection boundaries and faces the inward facing mirror surface of the at least one exterior curved reflection boundary.
