本论文的主要工作是利用有限元素法计算热带地区降雨对电波的衰减、相位旋转和交叉极化。计算了在20和30 GHz的扁球形雨滴的前向散射振幅，假设在垂直入射到雨滴轴的平面波。前向散射振幅获得所需的衰减，相位旋转，和交叉极化使用的降雨率数据尼日利亚，一个热带非洲国家。在这项工作中获得的结果与那些现有的公开文献进行比较。>
Computation of attenuation, phase rotation, and cross-polarization of radio waves due to rain in tropical regions using finite element method is the subject of this work. Computations are made of the forward-scattering amplitudes of oblate spheroidal raindrops at 20 and 30 GHz, assuming plane waves at normal incidence to the raindrop axis. The forward-scattering amplitudes are employed to obtain the required attenuation, phase rotation, and cross-polarization using the rainfall rate data for Nigeria, a tropical African country. The results obtained in this work compare with those existing in the open literature. >
