Invisibility cloaking has long been the realm of science fiction, but with the field of transformation optics, its fascination has become physical reality through engineered metamaterials that can control light in unconventional ways. (a) A virtual eye looks at a model with a metallic corrugation (black) covered by a unidirectional cloak (grey). (b) Ideally, this is what we want to see. (c) The bare corrugation without cloak. (d) The cloak is applied. (e) Time-of-flight imaging of the cloaking.
