| 1 | Calculation of angular glint in near field utilizing graphical electromagnetic computing显示文摘The angular glint in the near field plays an important role on radar tracking errors.To predict it more efficiently for electrically large targets,a new method based on graphical electromagnetic computing (GRECO) is proposed.With the benefit of the graphic card,the GRECO prediction method is faster and more accurate than other methods.The proposed method at the first time considers the special case that the targets cannot be completely covered by radar beams,which makes the prediction of radar tracking errors more self-contained in practical circumstances.On the other hand,the process of the scattering center extraction is omitted,resulting in possible angular glint prediction in real time.Comparisons between the simulation results and the theoretical ones validate its correctness and value to academic research and engineering applications. | Guangfu Zhang Chao Wang Liguo Liu Yunqi Fu Naichang Yuan | 2013 | Journal of Systems Engineering and Electronics2013，24，6： | 2 |

| 15 | Integrating electromagnetic surface and antenna array for reflection suppression and excellent radiation显示文摘The electromagnetic surface antenna array(EMSAA)has been proposed for obtaining reflection suppression and excellent radiation simultaneously.The antenna with rectangular radiation patch is used to design anisotropic electromagnetic surface.Preternatural reflection characteristics of the element antenna can be tailored depending on the incident polarizations.EMSAA can be constructed by using single structured element antenna with 90° rotation and orthometric arrangement.This orthometric arrangement of EMSAA is helpful to achieve reflection suppression and excellent radiation.The simulated results show that the reflection of EMSAA is suppressed from 5.0 GHz to 8.0 GHz with peak reduction of 12.3 dB.The linear-and circular-polarized radiation properties of EMSAA are obtained and the maximum gain is 14.3 dBi.The measured results are consistent with the simulation results.The results demonstrate that the reflection suppression and excellent radiation are achieved simultaneously.Such design of EMSAA will open the path for integrating antenna fields and electromagnetic surface(EMS)fields. | ZHENG Yuejun DING Liang CHEN Qiang GUO Min FU Yunqi | 2021 | Journal of Systems Engineering and Electronics2021，32，3： | 1 |

| 17 | Electric-controlled metasurface antenna array with ultra-wideband frequency reconfigurable reflection suppression显示文摘The electric-controlled metasurface antenna array(ECMSAA)with ultra-wideband frequency reconfigurable reflection suppression is proposed and realized.Firstly,an electriccontrolled metasurface with ultra-wideband frequency reconfigurable in-phase reflection characteristics is designed.The element of the ECMSAA is constructed by loading the single electric-controlled metasurface unit on the conventional patch antenna element.The radiation properties of the conventional patch antenna and the reflection performance of electric-controlled metasurface are maintained when the antenna and the metasurface are integrated.Thus,the ECMSAA elements have excellent radiation properties and ultra-wideband frequency reconfigurable in-phase reflection characteristics simultaneously.To take a further step,a 6×10 ECMSAA is realized based on the designed metasurface antenna element.Simulated and measured results prove that the reflection of the ECMSAA is dynamically suppressed in the P and L bands.Meanwhile,high-gain and multi-polarization radiation properties of the ECMSAA are achieved.This design method not only realizes the frequency reconfigurable reflection suppression of the antenna array in the ultra-wide frequency band but also provides a way to develop an intelligent low-scattering antenna. | ZHENG Yuejun CHEN Qiang DING Liang YUAN Fang FU Yunqi | 2023 | Journal of Systems Engineering and Electronics2023，34，6： | 0 |
| 18 | Loaded-frequency selective surface显示文摘A new frequency-selective surface(FSS)with loadings is introduced in this paper and analyzed by way of period moment methods(PMMs).The simulated results show that FSS may operate in different bands and especially generate a large reduction in the resonant frequency for a fixed unit cell size through different loadings.This provides a new orientation in the development for FSS.Practical circuits are fabricated,and the measured results agree well with the simulated results. | Qiang GAO Dunbao YAN Yunqi FU Naichang YUAN | 2008 | Frontiers of Electrical and Electronic Engineering in China2008，3，1： | 0 |
