TY - JOUR ID - citeulike:5743465 L3 - citeulike-article-id:5743465 N2 - The ability to render objects invisible using a cloak (such that they are not detectable by an external observer) has long been a tantalizing goal1, 2, 3, 4, 5, 6. Here, we demonstrate a cloak operating in the near infrared at a wavelength of 1,550 nm. The cloak conceals a deformation on a flat reflecting surface, under which an object can be hidden. The device has an area of 225 m2 and hides a region of 1.6 m2. It is composed of nanometre-size silicon structures with spatially varying densities across the cloak.
