In a new report on Science Advances, Su Xu and colleagues in engineering, nanotechnology, nanobionics and quantum information in China were inspired by the natural ecological relationship between transparent oceanic animals and their predators that employ a cross-wavelength detection strategy. The scientists 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 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. /news/2020-09-invisibility-cross-wavelength-tactics.html General 糖心视频ics Optics & Photonics Wed, 30 Sep 2020 10:10:50 EDT news520679446
