Notes on conformal invisibility devices
WebMay 25, 2006 · The principal distortions of invisibility are due to reflections and time delays. Reflections can be made exponentially small for devices that are large in comparison with the wavelength of light. Time delays are unavoidable and will result in wave-front dislocations. This paper considers invisibility devices based on optical conformal mapping. WebThis paper considers invisibility devices based on optical conformal mapping. The paper shows that the time delays do not depend on the directions of incidence, although the refractive-index profile of any conformal invisibility device is necessarily asymmetric. The distortions of images are thus uniform, which reduces the risk of detection.
