| Popis: | Hidden Under the Carpet Transformation optics, combined with the ability to fabricate structures with complex refractive index profiles, allow materials to be formed with fascinating optical properties, such as cloaks where both the object and the cloak concealing the object are rendered invisible. To date, the cloaks have been restricted to two dimensions, which limits realistic applications. Based on a photonic crystal structure with a polymer filling the empty space, Ergin et al. (p. 337 , published online 18 March) have designed, fabricated, and realized a three-dimensional cloak operating at optical wavelengths. |
