In a twist on the concept of an invisibility cloak, researchers have designed a material that not only makes an object invisible, but also generates one or more virtual images in its place. Because it doesn’t simply display the background environment to a viewer, this kind of optical device could have applications that go beyond a normal invisibility cloak. Plus, unlike previously proposed illusion devices, the design proposed here could be realized with artificial metamaterials.<\/strong><\/p>\n

The team of engineers, Wei Xiang Jiang, Hui Feng Ma, Qiang Cheng, and Tie Jun Cui from Southeast University in Nanjing, China, describes the recently developed class of optical transformation media as \u201cillusion media.\u201d As they explain in a new study, any object enclosed by such an illusion medium layer appears to be one or more other objects. The researchers\u2019 proposed device is designed to operate at microwave frequencies.<\/p>\n

\u201cThe illusion media make an enclosed object appear like another object or multiple virtual objects,\u201d Cui told\u00a0PhysOrg.com<\/em>. \u201cHence it can be applied to confuse the detectors or the viewers, and the detectors or the viewers can\u2019t perceive the real object. As a result, the enclosed object will be protected.\u201d<\/p>\n

\"Invisibility<\/p>\n

Illusion media can transform a real image into a virtual image. For example, a golden apple (the actual object) enclosed within the illusion medium layer appears as two green apples (the illusion) to any viewer outside the virtual boundary (dashed curves).
