摘要

本文利用并矢Green函数法

对湿冰球的消光截面、散射截面和吸收截面随湿冰球尺寸参数k

和融化水层厚度的变化进行了数值计算

并将它与同样尺寸的水球、冰球的特性作了比较。对于波长为2.5和0.868cm的两种无线电波

在方位角为0°和90°两种情况下

微分散射截面随仰角变化的特性也作了讨论。

Abstract

A numerical solution of the scattering characteristics of wet ice sphere is made by dyadic Green’s function method. The extinction cross section

scattering cross section and absorption cross section of the wet ice sphere as a function of radius parameter k0a0 and water layer thickness are calculated

and these results are compared with corresponding results of the ice sphere and water sphere. The differential scattering cross section of wet ice sphere as a function of the zenith angles and two azimuth angles φ=0° and φ=90° are discussed for two wavelengths λ =2.5cm and λ=0.868cm.
