| 1 | Generation of super-resolved optical needle and multifocal array using graphene oxide metalenses显示文摘Ultrathin flat metalenses have emerged as promising alternatives to conventional diffractive lenses,offering new possibilities for myriads of miniaturization and interfacial applications.Graphene-based materials can achieve both phase and amplitude modulations simultaneously at a single position due to the modification of the complex refractive index and thickness by laser conversion from graphene oxide into graphene like materials.In this work,we develop graphene oxide metalenses to precisely control phase and amplitude modulations and to achieve a holistic and systematic lens design based on a graphene-based material system.We experimentally validate our strategies via demonstrations of two graphene oxide metalenses:one with an ultra-long(~16λ)optical needle,and the other with axial multifocal spots,at the wavelength of 632.8 nm with a 200 nm thin film.Our proposed graphene oxide metalenses unfold unprecedented opportunities for accurately designing graphene-based ultrathin integratable devices for broad applications. | Hongtao Wang Chenglong Hao Han Lin Yongtian Wang Tian Lan Chengwei Qiu Baohua Jia | 2021 | Opto-Electronic Advances2021，4，2： | 10 |
| 2 | Selective excitation of resonances in gammadion metamaterials for terahertz wave manipulation显示文摘A gammadion terahertz(THz) metamaterial embedded with a pair of splits is experimentally investigated. By introducing the pair of splits at different arms, the transmitted amplitude at the resonance frequency can be manipulated from 61% to 24%. Broadband static resonance tunability from 1.11 to 1.51 THz is also demonstrated via varying the relative split positions at certain arms. The amplitude change and static resonance tunability are attributed to the introduced split pairs, which enable selective excitation of different resonance modes in the gammadion metamaterials. This work promises a new approach to design THz functional devices. | WANG DaCheng HUANG Qin QIU ChengWei HONG MingHui | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，8： | 2 |

| 8 | Mie series for electromagnetic scattering of chiral metamaterials sphere显示文摘The electromagnetic scattering of chiral metamaterials is simulated with the Mie series method.Based on the spherical harmonics vector function in chiral metamaterials,the electromagnetic fields inside and outside of chiral metamaterials sphere are expanded.By applying the continuous boundary condition between the chiral metamaterials and surrounding medium,and the transformation from linearly to circularly polarized electric field components,the co-polarized and cross-polarized bistatic radar cross scattering(RCS) of chiral metamaterials sphere are given.How to overcome the instability of chiral metamaterials sphere of Mie series formula is discussed.The electromagnetic scattering of chiral metamaterials,normal media and metamaterials are compared.The numerical results show that the existence of chirality ξ of chiral metamaterials can decrease the bistatic RCS compared with the same size as normal media sphere. | Maoyan Wang Chengwei Qiu Jun Xu Yuliang Dong Hu Zheng Hailong Li | 2011 | Journal of Systems Engineering and Electronics2011，22，6： | 1 |

| 10 | The prospects for bioprinting tumor models:recent advances in their applications显示文摘Three-dimensional(3D)tumor models prepared from patient-derived cells have been reported to imitate some of the biological development processes of in situ tumors in vitro.These 3D tumor models share several important characteristics with their in vivo tumor counterparts.Accordingly,their applications in tumor modeling,drug screening,and precision-targeted treatment are promising.However,the establishment of tumormodels is subject to several challenges,including advancements in scale size,repeatability,structural precision in time and space,vascularization,and the tumor microenvironment.Recently,bioprinting technologies enabling the editorial arrangement of cells,factors,and materials have improved the simulation of tumormodels in vitro.Among the 3D bioprinted tumor models,the organoidmodel has been widely appreciated for its advantages of maintaining high heterogeneity and capacity for simulating the developmental process of tumor tissues.In this review,we outline approaches and potential prospects for tumor model bioprinting and discuss the existing bioprinting technologies and bioinks in tumor model construction.The multidisciplinary combination of tumor pathology,molecular biology,material science,and additive manufacturing will help overcome the barriers to tumor model construction by allowing consideration of the structural and functional characteristics of in vitro models and promoting the development of heterogeneous tumor precision therapies. | Changru Zhang Xiaoqin Qiu Yu Dai Weiqing Kong Yihao Liu Haoyi Niu Chengwei Wang Xuelian Mi Hui Wang Ya Ren Han Yang Kerong Dai Jinwu Wang | 2023 | Bio-Design and Manufacturing2023，6，6： | 0 |
