We have compared radiative transfer theory with analytical solutions of the Maxwell equations for light scattering by multiple infinitely long parallel cylinders at perpendicular incidence. The calculated scattering cross sections for both methods show large differences, but the angle-dependent differential scattering cross-section results are very similar for small cylinder densities, except close to the forward direction. In contrast to recently published results, it is shown that the radiative transfer equation is a useful approximation for small cylinder concentrations.
我们已将辐射传输理论与麦克斯韦方程组的解析解进行了比较，该解析解用于计算垂直入射时多个无限长平行圆柱体的光散射。两种方法计算出的散射截面显示出很大差异，但对于小圆柱体密度，除了靠近前向方向外，角度相关的微分散射截面结果非常相似。与最近发表的结果相反，结果表明辐射传输方程对于小圆柱体浓度是一种有用的近似。
