研究了自由空间中半波偶极子云团的极化散射截面问题 ,并利用二次辐射理论 ,研究了单个偶极子的极化散射过程 ,然后利用偶极子云团的非相干散射模型 ,得到了在各种入射极化条件下偶极子云团散射截面的计算公式 ,并纠正了长期以来存在于经典文献中有关偶极子云团散射截面的错误结论。
The problem of polarization scattering cross section of half-wave dipole cloud in free space is studied. The polarization scattering of a single dipole is studied by using the theory of secondary radiation. Then, by using the incoherent scattering model of dipole cloud The formulas for calculating the scattering cross sections of dipole clouds under various incident polarizations are obtained and the erroneous conclusions about the scattering cross sections of dipolar clouds existing in classical literature for a long time have been corrected.
