Photonics.com Weekly: Active Invisibility Cloak Goes Broadband (12/26/2013)

Active Cloak Most Broadband to Date Active Cloak Most Broadband to Date
An active invisibility cloak — that is, one designed to work with an external power source — could significantly broaden the device's operation bandwidth, moving its applications beyond camouflage. “Many cloaking designs are good at suppressing the visibility under certain conditions, but they are inherently limited to work for specific colors of light or specific frequencies of operation," said Andrea Alù of the University of Texas at Austin. But in his team's work, “we prove that cloaks can become broadband, pushing this technology far beyond current limits of passive cloaks. I believe that our design helps us understand the fundamental challenges of suppressing the scattering of various objects at multiple wavelengths and shows a realistic path to overcome them.”
