摘要: 本文提出了多層吸收介質球電磁散射的散射系數(shù)an和bn的遞推公式及其適用于計算機數(shù)值計算的形式。它對各種介質的復折射率和粒子尺寸參數(shù)均能獲得穩(wěn)定和收斂的數(shù)值結果。Abstract: More stable and accurate recursive formulas and a computing procedure to calculate scattering coefficients for a multilayered sphere are proposed. The procedure involves three logarithmic derivatives of Ricatti-Bessel functions 'n(z)/n(z), 'n(z)/n(z),'n(z)/n(z), as well as the ratio n(z)/n(z). The asymptotic behavior, stability, and accuracy of the procedure and scattering coefficients an, and bn are discussed for various complex refractive indices. This procedure can be applied to large and small inhomogeneous spherical particles.
