2Wideband diffusion metabsorber for perfect scattering field reduction显示文摘Both absorption and diffuse reflection can effectively suppress microwave backward reflection.However,the challenge of designing wideband absorptive elements with anti-phase reflection hinders the simultaneous working of the two principles.With aid of the wideband characteristic of bilateral complementary structure,we propose a strategy to design wideband absorptive elements with large reflection phase differences.For proof of concept,the proposed elements are arranged in a rectangular grid by optimizing scattering field distribution.The proposed diffusion metabsorber achieves over 20-dB scattering field reduction in the range of 8.5–20.3 GHz with good polarization stability and high angular insensitivity of up to±40°,which has been verified by real experiments.Furthermore,the proposed design strategy exhibits the potential to further reduce electromagnetic wave reflection,and the optical transparent characteristic is promising for window applications.ZICHENG SONG PINGPING MIN JIAQI ZHU LEI YANG FENG HAN LIN 2022Photonics Research2022,10,6:1

4Nitrogen-rich Graphdiyne Film for Efficiently Suppressing the Methanol Crossover in Direct Methanol Fuel Cells显示文摘The inhibition of the methanol crossover is one of the intractable challenges in the direct methanol fuel cell.The graphdiyne(GDY)with atomic-level pores shows great potential in realizing the zero-permeation of methanol molecules.In this paper,an ultrathin layer of nitrogen-rich GDY film with a high nitrogen content is largely prepared and readily used for retarding the methanol permeation in the state-of-the-art commercial Nafion membrane.The high N-content in this porous GDY nanofilm remarkably increases the selective suppression in methanol transfer,and single-layer GDY film can efficiently prevent 43%methanol crossover and the value of the double-layer GDY film can be high up to 69%.The power performance and the long-term stability of the cell are obviously improved due to the reduced methanol crossover.LI Liang ZUO Zicheng HE Feng JIANG Zhongqing LI Yuliang 2021Chemical Research in Chinese Universities2021,37,6:0
5Synthetic aperture metalens显示文摘Metalenses are ultrathin optical elements that can focus light using densely arranged subwavelength structures.Due to their minimal form factor,they have been considered promising for imaging applications that require extreme system size,weight,and power,such as in consumer electronics and remote sensing.However,as a major impediment prohibiting the wide adoption of the metalens technology,the aperture size,and consequently the imaging resolution,of a metalens are often limited by lithography processes that are not scalable.Here,we propose to adopt a synthetic aperture approach to alleviate the issue,and experimentally demonstrate that,assisted by computational reconstruction,a synthetic aperture metalens composed of multiple metalenses with relatively small aperture size can achieve an imaging resolution comparable to a conventional lens with an equivalent large aperture.We validate the concept via an outdoor imaging experiment performed with a synthetic aperture metalens-integrated near-infrared camera using natural sunlight for target illumination.FENG ZHAO ZICHENG SHEN DECHENG WANG BIJIE XU XIANGNING CHEN YUANMU YANG 2021Photonics Research2021,9,12:0
