我们考虑满足两个条件的任意形状粒子的散射：（1）粒子相对于环境介质的极化率比1小，（2）粒子引入的相移小于2。我们通过使用连续迭代的方法然后应用傅里叶变换来求解Shifrin提出的积分微分方程。对于第二次迭代，给出的结果准确地描述了一大类粒子的散射。散射矩阵的相位函数和其他元素与球形散射体的米氏理论非常一致。
We consider scattering by arbitrarily shaped particles that satisfy two conditions: (1) that the polarizability of the particle relative to the ambient medium be small compared to 1 and (2) that the phase shift introduced by the particle be less than 2. We solve the integro-differential equation proposed by Shifrin by using the method of successive iterations and then applying a Fourier transform. For the second iteration, results are presented that accurately describe scattering by a broad class of particles. The phase function and other elements of the scattering matrix are shown to be in excellent agreement with Mie theory for spherical scatterers.
