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

  • 摘要: 該文基于迭代散射算法(ISP)對(duì)柱體陣列的散射場(chǎng)進(jìn)行分析。通過矢量柱面波函數(shù)展開,根據(jù)理想導(dǎo)體表面邊界條件,建立柱體表面入射場(chǎng)與散射場(chǎng)的關(guān)系式。將前一次迭代時(shí)柱體陣列的近區(qū)散射場(chǎng)作為下一次迭代的入射場(chǎng),推導(dǎo)出柱體陣列散射場(chǎng)系數(shù)間的迭代關(guān)系。通過分析不同迭代次數(shù)下2~4個(gè)柱體的散射場(chǎng),確定3次迭代即可保證算法的準(zhǔn)確度。對(duì)比數(shù)值結(jié)果表明,迭代散射算法具有與矩量法(MoM)結(jié)果同等的準(zhǔn)確度,并具有明顯優(yōu)于矩量法的計(jì)算速度。
