| 1 | Anti-plane problem of four edge cracks emanating from a square hole in piezoelectric solids显示文摘By constructing a new numerical conformal mapping and using the Stroh-type formulism, an anti-plane problem of four edge cracks emanating from a square hole in piezoelectric solids is investigated. The explicit expressions of the complex potential function, field intensity factors, energy release rates and mechanical strain energy release rate near the crack tip are obtained under the assumptions that the surfaces of the cracks and hole are electrically permeable and electrically impermeable. Numerical examples are presented to show the influences of the geometrical parameters of defects and applied mechanical/electrical loads on the energy release rate and mechanical strain energy release rate under two electrical boundary conditions. | Fan Shiwang Guo Junhong Yu Jing | 2017 | Chinese Journal of Aeronautics2017，30，1： | 9 |

| 3 | Periodic solutions of periodically perturbed functional differential equations显示文摘By using the generalized degree theory, some periodically perturbed functional differential equations have been proved to have at least one periodic solution if the associated homogeneous linear equations have no nontrivial periodic solution. Some known results are generalized. | Shiwang Ma Zhicheng Wang Jianshe Yu | 1998 | Chinese Science Bulletin1998，43，23： | 0 |
| 4 | Electromagnetic wave manipulation based on few-layer metasurfaces and polyatomic metasurfaces显示文摘Metasurfaces,whose electromagnetic(EM)responses can be artificially designed,are two-dimensional arrays composed of subwavelength nanostructures.Accompanied by various fascinating developments in the past decade,metasurfaces have been proved as a powerful platform for the implementation of EM wave manipula-tion.However,the planar monoatomic metasurfaces widely used in previous works have limited design freedoms,resulting in some disadvantages for the realization of high-performance and new functional EM wave control.The latest developments show that few-layer metasurfaces and polyatomic metasurfaces are good alternatives to overcome the drawbacks of planar monoatomic metasurfaces and realize high-efficient,multi-band and broad-band EM functionalities.They provide additional degrees of design freedom via introducing multilayer layouts or combining multiple meta-atoms into a unit cell respectively.Here,recent advances of few-layer and polyatomic metasurfaces are reviewed.The design strategies,EM properties and main advantages of few-layer metasurfaces and polyatomic metasurfaces are overviewed firstly.Then,few-layer metasurfaces and polyatomic metasurfaces in recent progress for EM wave manipulation are classified and discussed from the viewpoint of their design strategy.At last,an outlook on future development trends and potential applications in these fast-developing research areas is presented. | Shiwang Yu Jiaqi Cheng Zhancheng Li Wenwei Liu Hua Cheng Jianguo Tian Shuqi Chen | 2022 | ChemPhysMater2022，1，1： | 0 |
