摘要

在这项研究中，我们研究了在WKB近似中锥形冰晶的形状因子对其几何特征(形状、空间取向、纵横比和尺寸参数)的敏感性。利用WKB方法，导出了水平取向方形金字塔形状因子的解析公式。我们将通过将WKB近似应用于围绕其主轴旋转的粒子的情况来开始这项工作。然后，我们将在未来的工作中处理一个粒子围绕垂直于其主轴的轴旋转的情况。此外，还给出了消光系数。为了说明我们的分析结果，文中还分析了一些数值算例。

Light scattering by horizontally oriented square pyramid in the Wentzel–Kramers–Brillouin approximation

In this research, we studied the sensitivity of the form factor of a pyramidal ice crystal in the Wentzel–Kramers–Brillouin (WKB) approximation to its geometrical characteristics: the shape, spatial orientation, aspect ratio and size parameter. Using the WKB method, we derive an analytical formula of the form factor of horizontally oriented square pyramid. We will begin this work by applying the WKB approximation to the case of a particle which rotates about its main axis. Then, we will move to deal with the case of a particle which rotates about an axis perpendicular to its main axis in a future work. In addition, the coefficient of extinction is also given. To illustrate our analytical results, some numerical examples are analyzed.
