Abstract
Digital cloaking is a method for practical cloaking, where space, angle, spectrum and phase are discretized. At the sacrifice of spatial resolution, a good approximation to an ideal cloak can be achieved—a cloak that is omnidirectional, broadband, and operational for the visible spectrum, three-dimensional (3D), and phase-matching for the light field, among other attributes. One example of a digital cloak is an active cloak that uses lenticular lenses, similar to integral imaging for 3D displays. With the continuing improvement in commercial digital technology, the resolution limitations of a digital cloak may be minimized, and a wearable cloak can be implemented.
