After researchers at the University of Illinois found the silicon photonic crystals as the key to optical cloaking in June, 2008, engineers at Duke University recently has produced a new type of cloaking device, which is significantly more sophisticated at cloaking in a broad range of frequencies.
ScienceDaily reported, the engineers develop some technique using mathematical algorithm, as the base of the design and fabrication. The exotic composite materials known then called as metamaterials.
It was reported that the electromagnetic waves around an object, only to have them emerge on the other side as if they had passed through an empty volume of space. What does the finding mean?
“The new device can cloak a much wider spectrum of waves — nearly limitless — and will scale far more easily to infrared and visible light. The approach we used should help us expand and improve our abilities to cloak different types of waves”, said Smith, senior member of the research team.
