According to sources, the researchers said that controlling and bending light around an object so that it appears invisible to the naked eye is the theory behind fictional invisibility cloaks.

Debashis Chanda along with other fellow researchers at the University of Central Florida have managed to create artificial nanostructures that can do the job, called metamaterials.

Chanda and fellow optical and nanotech experts were able to develop a larger swath of multilayer 3D metamaterial operating in the visible spectral range.

Researchers have reportedly stated that control of electromagnetic resonances over the 3-D space by structural manipulation allows precise control over propagation of light. Following this technique, larger pieces of this special material can be created, which were previously limited to micron-scale size.

Researchers also believe that by improving the technique, the team may be able to create larger pieces of the material with engineered optical properties, which would make it practical to produce for real-life device applications. For example, the team could develop large-area metamaterial absorbers, which would enable fighter jets to remain invisible from detection systems.

According to sources, other members of the research team include: Li Gao, Youngmin Kim, Kazuki Shigeta, Steven Hartanto and John Rogers from the University of Illinois at Urbana-Champaign; Abraham Vasquez-Guardado and Daniel Franklin from UCF: Christopher J Progler from Photronics Inc. and Gregory R. Bogart from the Sandia National Laboratories.
