Scientists develop world's first BATTERY-OPERATED invisibility cloak

“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,” Alù explains . The active cloak uses a battery, circuits and amplifiers to reduce scattering of light and radio signals over a broader range of frequencies. The team also hopes that their work will improve wireless communications, biomedical sensing, near-field imaging and energy harvesting devices.
