| 1 | Tunable/Reconfigurable Metasurfaces: Physics and Applications显示文摘Metasurfaces,ultrathin metamaterials constructed by planar meta-atoms with tailored electromagnetic(EM)responses,have attracted tremendous attention due to their exotic abilities to freely control EM waves.With active elements incorporated into metasurface designs,one can realize tunable and/or reconfgurable metadevices with functionalities controlled by external stimuli,opening a new platform to dynamically manipulate EM waves.In this article,we briefy review recent progress on tunable/reconfgurable metasurfaces,focusing on their working mechanisms and practical applications.We frst describe available approaches,categorized into diferent classes based on external stimuli applied,to realize homogeneous tunable/reconfgurable metasurfaces,which can ofer uniform manipulations on EM waves.We next summarize recent achievements on inhomogeneous tunable/reconfgurable metasurfaces with constitutional meta-atoms locally tuned by external knobs,which can dynamically control the wave-fronts of EM waves.We conclude this review by presenting our own perspectives on possible future directions and existing challenges in this fast developing feld. | Qiong He Shulin Sun Lei Zhou | 2019 | Research2019，，1： | 26 |
| 2 | A journey to understand wheat Fusarium head blight resistance in the Chinese wheat landrace Wangshuibai显示文摘Fusarium head blight(FHB) or scab caused by Fusarium graminearum is a major threat to wheat production in China as well as in the world. To combat this disease, multiple efforts have been carried out internationally. In this article, we review our long-time effort in identifying the resistance genes and dissecting the resistance mechanisms by both forward and reverse genetics approaches in the last two decades. We present recent progress in resistance QTL identification, candidate functional gene discovery, marker-assisted improvement of FHB resistant varieties, and findings in investigating association of signal molecules, such as Ca^(++),SA, JA, and ET, with FHB response, with the assistance from rapidly growing genomics platforms. The information will be helpful for designing novel and efficient approaches to curb FHB. | Haiyan Jia Jiyang Zhou Shulin Xue Guoqiang Li Haisheng Yan Congfu Ran Yiduo Zhang Jinxing Shi Li Jia Xin Wang Jing Luo Zhengqiang Ma | 2018 | The Crop Journal2018，6，1： | 24 |
| 3 | High-efficiency surface plasmon meta-couplers: concept and microwave-regime realizations显示文摘Surface plasmon polaritons(SPPs)and their low-frequency counterparts(i.e.,spoof SPPs on artificial surfaces)have recently found numerous applications in photonics,but traditional devices to excite them(such as gratings and prism couplers)all suffer from problems of inherent low efficiency because the generated SPPs can decouple,returning to free space,and reflections at the device surface can never be avoided.Here,we propose a new SPP excitation scheme based on a transparent gradient metasurface and numerically demonstrate that it exhibits inherently high efficiency(~94%)because the designed meta-coupler suppresses both decoupling and surface reflections.As a practical realization of this concept,we fabricated a meta-coupler for operation in the microwave regime and performed near-field and far-field experiments to demonstrate that the achieved excitation efficiency for spoof SPPs reaches~73%,which is several times higher than that achieved by other available devices in this frequency domain.Our findings can motivate the design and fabrication of high-performance plasmonic devices to harvest light–matter interactions,particularly those related to spoof SPPs in the low-frequency domain. | Wujiong Sun Qiong He Shulin Sun Lei Zhou | 2016 | Light(Science & Applications)2016，5，1： | 23 |
| 4 | Simultaneous changes in seed size, oil content and protein content driven by selection of SM/EEIhomologues during soybean domestication显示文摘Soybean accounts for more than half of the global production of oilseed and more than a quarter of the protein used globally for human food and animal feed.Soybean domestication involved parallel increases in seed size and oil content,and a concomitant decrease in protein content.However,science has not yet discovered whether these effects were due to selective pressure on a single gene or multiple genes.Here,re-sequencing data from>800 genotypes revealed a strong selection during soybean domestication on GmSWEETlOa.The selection of GmSWEETlOa conferred simultaneous increases in soybean-seed size and oil content as well as a reduction in the protein content.The result was validated using both near-isogenic lines carrying substitution of haplotype chromosomal segments and transgenic soybeans.Moreover,GmSWEETlOb was found to be functionally redundant with its homologue GmSWEETlOa and to be undergoing selection in current breeding,leading the the elite allele GrnSWEETlOb,a potential target for present-day soybean breeding.Both GmSWEETlOa and GmSWEETlOb were shown to transport sucrose and hexose,contributing to sugar allocation from seed coat to embryo,which consequently determines oil and protein contents and seed size in soybean.We conclude that past selection of optimal GmSWEETlOa alleles drove the initial domestication of multiple soybean-seed traits and that targeted selection of the elite allele GmSWEETlOb may further improve the yield and seed quality of modern soybean cultivars. | Shoudong Wang Shulin Liu Jie Wang Kengo Yokosho Bin Zhou Ya-Chi Yu Zhi Liu Wolf BFrommer Jian Feng Ma Li-Qing Chen Yuefeng Guan Huixia Shou Zhixi Tian | 2020 | National Science Review2020，7，11： | 17 |
| 5 | A hybrid invisibility cloak based on integration of transparent metasurfaces and zero-index materials显示文摘The invisibility cloak,a long-standing fantastic dream for humans,has become more tangible with the development of metamaterials.Recently,metasurface-based invisibility cloaks have been proposed and realized with significantly reduced thickness and complexity of the cloaking shell.However,the previous scheme is based on reflection-type metasurfaces and is thus limited to reflection geometry.In this work,by integrating the wavefront tailoring functionality of transparent metasurfaces and the wave tunneling functionality of zero-index materials,we have realized a unique type of hybrid invisibility cloak that functions in transmission geometry.The principle is general and applicable to arbitrary shapes.For experimental demonstration,we constructed a rhombic double-layer cloaking shell composed of a highly transparent metasurface and a double-zero medium consisting of dielectric photonic crystals with Dirac cone dispersions.The cloaking effect is verified by both full-wave simulations and microwave experimental results.The principle also reveals exciting possibilities for realizing skin-thick ultrathin cloaking shells in transmission geometry,which can eliminate the need for spatially varying extreme parameters.Our work paves a path for novel optical and electromagnetic devices based on the integration of metasurfaces and metamaterials. | Hongchen Chu Qi Li Bingbing Liu Jie Luo Shulin Sun Zhi Hong Hang Lei Zhou Yun Lai | 2018 | Light(Science & Applications)2018，7，1： | 13 |
| 6 | Controlling angular dispersions in optical metasurfaces显示文摘Although metasurfaces have shown great potential for manipulating light,most previously realized meta-devices suffer from uncontrolled angular dispersions,making them unfavorable for many applications.Here,we propose a general strategy to realize optical metasurfaces with desired angular dispersions based on carefully controlling both the near-field couplings between meta-atoms and the radiation pattern of a single meta-atom.Utilizing such a strategy,we experimentally demonstrate a series of optical meta-devices with predesigned angular dispersions,including two incident-angle-insensitive absorbers,one incident-angle-selective absorber,and one multifunctional meta-polarizer whose functionality changes from a perfect mirror to a half-waveplate as the excitation angle varies.Finally,we design a gradient meta-device using meta-atom arrays with purposely controlled angular dispersions and numerically demonstrate that it can exhibit distinct wavefront-control functionalities when illuminated at different incident angles.Our findings establish a new platform for achieving angle-multiplexed functional meta-devices,significantly expanding the wave-manipulation capabilities of optical metasurfaces. | Xiyue Zhang Qi Li Feifei Liu Meng Qiu Shulin Sun Qiong He Lei Zhou | 2020 | Light(Science & Applications)2020，9，1： | 11 |
| 7 | Efficient manipulations of circularly polarized terahertz waves with transmissive metasurfaces显示文摘The unrestricted control of circularly polarized(CP)terahertz(THz)waves is important in science and applications,but conventional THz devices suffer from issues of bulky size and low efficiency.Although Pancharatnam-Berry(PB)metasurfaces have shown strong capabilities to control CP waves,transmission-mode PB devices realized in the THz regime are less efficient,limiting their applications in practice.Here,based on Jones matrix analysis,we design a trilayer structure(thickness of ~λ/5)and experimentally demonstrate that the structure can serve as a highly efficient transmissive meta-atom(relative efficiency of ~90%)to build PB metadevices for manipulating CP THz waves.Two ultrathin THz metadevices are fabricated and experimentally characterized with a z-scan THz imaging system.The first device can realize a photonic spin Hall effect with an experimentally demonstrated relative efficiency of ~90%,whereas the second device can generate a high-quality background-free CP Bessel beam with measured longitudinal and transverse field patterns that exhibit the nondiffracting characteristics of a Bessel beam.All the experimental results are in excellent agreement with full-wave simulations.Our results pave the way to freely manipulate CP THz beams,laying a solid basis for future applications such as biomolecular control and THz signal transportation. | Min Jia Zhuo Wang Heting Li Xinke Wang Weijie Luo Shulin Sun Yan Zhang Qiong He Lei Zhou | 2019 | Light(Science & Applications)2019，8，1： | 9 |
| 8 | Scatterings from surface plasmons to propagating waves at plasmonic discontinuities显示文摘Surface plasmon polaritons (SPPs) and their low-frequency counterpart spoof SPPs have attracted intensive interests in sciences [1,2], due to their unprecedented capabilities to confine electromagnetic (EM) fields at deep-subwavelength scale, leading to many applications such as super-resolution imaging [3], plasmonic lasers [4], surfaced-enhanced Raman effect [5], plasmonic waveguides [6,7] or circuits [8], etc. In practice, scatterings of SPPs to propagating waves (PWs) are inevitable as SPPs encounter discontinuities (say, interfaces between two different plasmonic systems). Such scatterings can lead to undesired radiation losses which should be avoided, especially in those applications employing SPPs as information carriers (say, plasmonic waveguides and nano-circuits [6–8]). Meanwhile, SPP-PW scatterings can also be utilized to achieve certain desired functionalities. For example, one can purposely place a set of carefully designed scatters on a plasmonic surface to scatter SPPs, generating fascinating effects such as holograms, focusing, or even directional radiations [9,10]. However, theoretical understandings on the inherent physics governing SPP-PW scatterings are far from satisfactory. Without a simple picture on such processes, people usually have to rely on full-wave simulations to optimize the devices to either suppress or utilize the SPP-PW scatterings. Although several theoretical approaches were proposed to study the SPP transmission/ reflection behaviors at certain plasmonic interfaces [11,12], the SPP-PW scatterings are usually overlooked. Moreover, since PWs have infinite channels to transport in free space, it is difficult to derive an analytical formula to describe such SPP-PW processes. | Fuxin Guan Shulin Sun Shiyi Xiao Qiong He Lei Zhou | 2019 | Science Bulletin2019，64，12： | 4 |
| 9 | Space-confined growth of monolayer ReSe2 under a graphene layer on Au foils显示文摘Vertical heterostructures based on two-dimensional(2D)materials have attracted widespread interest for their numerous applications in electronic and optoelectronic devices.Herein,we report the direct construct!on of an abnormal graphene/ReSe2 stack on Au foils by a two-step chemical vapor deposition(CVD)strategy.During the second growth stage,mono layer ReSe2 is found to prefere ntially evolve at the irUerface between the first-grown graphene layer and the Au substrate.The unusual stacking behavior is unraveled by in-situ'cutting open'the upper graphene from the defects to expose the lower ReSe2 using scanning tunneling microscopy(STM).From combination of these results with density functional theory calculations,the domain boundaries and edge sites of graphene are proposed to be adsorption sites for Re and Se precursors,further facilitating the growth of ReSe2 at the van der Waals gap of graphene/Au.This work hereby offers an intriguing strategy for obtaining vertical 2D heterostructures featured with an ultra-clean interface and a designed stacking geometry. | Chunyu Xie Shaolong Jiang Xiaolong Zou Yuanwei Sun Liyun Zhao Min Hong Shulin Chen Yahuan Huan Jianping Shi Xiebo Zhou Zhepeng Zhang Pengfei Yang Yuping Shi Porun Liu Qing Zhang Peng Gao Yanfeng Zhang | 2019 | Nano Research2019，12，1： | 4 |

| 12 | Efficient generation of complex vectorial optical fields with metasurfaces显示文摘Vectorial optical fields(VOFs)exhibiting arbitrarily designed wavefronts and polarization distributions are highly desired in photonics.However,current methods to generate them either require complicated setups or exhibit limited functionalities,which is unfavorable for integration-optics applications.Here,we propose a generic approach to efficiently generate arbitrary VOFs based on metasurfaces exhibiting full-motrix yet inhomogeneous Jones-matrix distributions.We illustrate our strategy with analytical calculations on a model system and an experimental demonstration of a meta-device that can simultaneously deflect light and manipulate its polarization.Based on these benchmark results,we next experimentally demonstrate the generation of a far-field VOF exhibiting both a vortex wavefront and an inhomogeneous polarization distribution.Finally,we design/fabricate a meta-device and experimentally demonstrate that it can generate a complex near-field VOF-a cylindrically polarized surface plasmon wave possessing orbital angular momentum-with an efficiency of-34%.Our results establish an efficient and ultracompact platform for generating arbitrary predesigned VOFs in both the near-and far-fields,which may find many applications in optical manipulation and communications. | Dongyi Wang Feifei Liu Tong Liu Shulin Sun Qiong He Lei Zhou | 2021 | Light(Science & Applications)2021，10，4： | 3 |

| 14 | Amelioration of weld-crack resistance of the M951 superalloy by engineering grain boundaries显示文摘Fusion weld is a portable and economical joining and repairing method of metals.However,weld cracks often occur during the fusion weld of Ni-base superalloys,which hinder the applications of fusion weld on this kind of materials.In this work,the effects of microstructures of grain boundaries(GBs)of the prototype M951 superalloy on its weldability were investigated.The precipitated phases,the elemental segregations on GBs,and the morphologies of GBs can be largely altered by regulating the cooling rates of pre-weld heat treatments.With decreasing the cooling rate,chain-like M_(23)X_(6)phase precipitates along the GBs,accompanying segregations of B,and GBs becomes more serrated in morphology.During fusion weld,the engineered GBs in the M951 superalloy with a low cooling rate favor the formation of the continuous liquid films on GBs,which together with the serrated GB morphology significantly prevents the formation of weld cracks.Our findings imply that the weld-crack resistance of the superalloys can be ameliorated by engineering GBs. | Mingyue Wen Yuan Sun Jinjiang Yu Shulin Yang Xingyu Hou Yanhong Yang Xiaofeng Sun Yi Zhou Zhou | 2021 | Journal of Materials Science & Technology2021，，19： | 2 |

| 16 | Calculation model of military aircraft survivability to a missile显示文摘Since missiles are main threat against aircrafts in air war,a model is proposed for calculating the aircraft survivability to a missile.The hit characteristic of aircraft to a missile is analyzed,and then Monte Carlo method is applied to generate missile detonation location according to its distribution rule.In addition,based on the analysis of fragment trajectory and critical components,the intersection point of these two is determined.Then the kill probability of critical component to a fragment can be calculated,and the aircraft survivability to a missile is obtained accordingly.Finally,the feasibility of the proposed method is demonstrated.Simulation results show that this method captures the basic effects of missile detonation locations on aircraft survivability,which may provide an effective reference to aircraft survivability research. | 杨哲 Li Shulin Li Shouan Zhou Li Zhang Jun | 2014 | High Technology Letters2014，20，2： | 1 |
