Abstract
A cloaking device includes an object-side, an image-side, a cloaked region (CR) between the object-side and the image-side. An object-side CR reflection boundary and a plurality of object-side color filters are positioned on the object side and an image-side CR reflection boundary and a plurality of image-side color filters are positioned on the image-side. The plurality of object-side color filters are spaced apart from and positioned generally parallel to the object-side CR reflection boundary, and the plurality of image-side color filters are spaced apart from and positioned generally parallel to the image-side CR reflection boundary. The plurality of object-side color filters and the plurality of image-side color filters may be co-planar and light from an object located on the object-side of the cloaking device propagates via at least two optical paths to form an image of the object on the image-side of the cloaking device.
