Oceanic animals and their predators employ a cross-wavelength detection strategy. Inspired by these animals an international team of researchers (China, USA – UC Berkeley, Lawrence Berkeley National Laboratory, Duke University) proposed a new concept of cross-wavelength invisibility that integrated a variety of invisibility tactics. They presented a Boolean metamaterial design strategy to balance divergent material requirements across cross-scale wavelengths. As a proof of concept, they simultaneously demonstrated longwave cloaking and shortwave transparency using a nanoimprinting technique. The work extended stealth techniques from individual strategies of invisibility targeting a single-wavelength spectrum to integrated invisibility targeting cross-wavelength applications. These experiments will pave the way to develop cross-wavelength integrated metadevices…read more. Open Access TECHNICAL ARTICLE
