In this research, we propose a simple approximation technique based on the decomposition of particles and on the Wentzel-Kramers-Brillouin approximation (WKB). The latter allows us to express analytically the expression of the form factor of a particle of a regular prismatic ice crystal shape. Our focus will be on studying the light scattering by horizontally oriented prismatic particles which rotate about their principal axes. To illustrate our formalism, a few numerical examples will be analyzed.

水平取向棱柱粒子光散射的 Wentzel-Kramers-Brillouin 近似

在这项研究中，我们提出了一种基于粒子分解和 Wentzel-Kramers-Brillouin 近似 (WKB) 的简单近似技术。后者允许我们分析地表达规则棱柱冰晶形状的粒子的形状因子的表达。我们的重点将是研究围绕主轴旋转的水平取向的棱柱粒子对光的散射。为了说明我们的形式主义，将分析一些数值例子。
