Analysis on Scattering Characteristics of Cylinder Array Based on Iterative Scattering Algorithm

  • 摘要: 该文基于迭代散射算法(ISP)对柱体阵列的散射场进行分析。通过矢量柱面波函数展开,根据理想导体表面边界条件,建立柱体表面入射场与散射场的关系式。将前一次迭代时柱体阵列的近区散射场作为下一次迭代的入射场,推导出柱体阵列散射场系数间的迭代关系。通过分析不同迭代次数下2~4个柱体的散射场,确定3次迭代即可保证算法的准确度。对比数值结果表明,迭代散射算法具有与矩量法(MoM)结果同等的准确度,并具有明显优于矩量法的计算速度。
