摘    要:利用各向异性时域有限差分法(FDTD),分析填充不同介质凹槽的金属目标的电磁散射。对具有旋转对称特性的典型目标模型,计算并分析了在金属目标表面开凹槽的宽度和深度对其电磁散射特性的影响,计算结果显示,在目标的特定部位开适当宽度和深度的槽并填充负单轴各向异性介质,能显著降低目标的后向雷达散射截面(RCS)。

关 键 词:各向异性  时域有限差分  凹槽  雷达散射截面  电磁散射

Abstract:The Finite-Difference Time Domain (FDTD) algorithms of anisotropic material was used to analyze the plan wave scattering by slots on aircraft loaded with anisortopic material. This paper calculated the impact of the width and depth of the slot on the scattering characteristics of the rotationally symmetric model. Numerical results showed that the backscatter can be greatly reduced by using negative uniaxial anisotropic media to fill in the slots of the proper width and depth at the specific position of the model.
Keywords:anisotropic  FDTD  slot  RCS  electro-magnetic scattering
