| 摘 要： | 用时域有限差分(Finite difference-time domain,FD-TD)法分析计算了由碳纤维复合材料(Carbon fiber reinforced polymer,CFRP)单向板组成的二面角的电磁反射特性.计算结果表明,碳纤维二面角的雷达散射截面(Radar cross section,RCS)对纤维方向和极化方向敏感.当两块板的纤维方向垂直时,对极化方向敏感度降低.

| Abstract: | The electromagnetic scattering characteristics for the dihedral angle composed of carbon fiber reinforced polymer (CFRP) unidirectional laminate are calculated and analyzed by using finite differencetime domain (FD-TD) method. The calculated results demonstrate that the radar cross section (RCS) of the dihedral angle is sensitive to the direction of the fiber and the polarization. And the sensitivity is reduced when the fiber direction in the two laminates of the dihedral angle is perpendicular. Results provide a reference for the aircraft stealth design. |
