摘要
本文根据广义米氏理论，将入射高斯波束用矢量球谐函数展开，研究多层介质球的电磁（光）散射。提出波束因子ｇｎ的改进算法以及散射系数ａｎ和ｂｎ的迭代公式和算法，并进行了数值计算与讨论。
Based on the generalized Lorentz-Mie theory(GLMT), the incident fundamental Gaussian beam is expanded in terms of the vector spherical harmonics. The interaction of Gaussian beam with a multi Lagered sphere located on the propagation axis is analyzed. The modified algorithm for wave beam parameter gn and the recursive formulas as well as the computing procedure to calculate scattering coefficients an and bn are proposed. And the numerrical results are discussed and compared.
