摘要

将特征基函数法(CBFM)应用于1 ~ 35 GHz频率范围内的三维全波模型,结合体积积分方程公式(VIEF),高效、准确地计算了复杂形状降水颗粒的电磁散射特性。用新方法得到的初步结果与用离散偶极子近似和米氏理论得到的结果很好地符合球形粒子的测试实例。

Application of 3D MoM/CBFM technique to the problem of electromagnetic scattering by complex-shaped precipitation particles
The Characteristic Basis Function Method (CBFM) is applied to a 3D full-wave model, in conjunction with the volume-integral equation formulation (VIEF), in the frequency range of 1-35 GHz to calculate the electromagnetic scattering properties of complex-shaped precipitation particles in an efficient and accurate manner. Preliminary results derived by the use of the new approach are shown to be in good agreement with those obtained with the discrete dipole approximation and the Mie theory for the test example of a spherical particle.
