摘要
本文提出了一种用于计算任意取向多个介质椭球电磁散射的混合方法 .利用扩展边界条件 (EBC)导出具有旋转轴对称单个椭球以球面波矢量函数为基底的T矩阵 ,结合球矢量波函数旋转定理和递推T矩阵方法 ,给出多个任意取向介质椭球的散射场 .
This paper presents a hybrid scheme for calculation many dielectric spheroids in arbitrary orientations.Firstly,the T matrix of single particle with symmetrical axis is obtained by extend boundary condition method,and that of the prolate spheroids,as an example,can be work out easily.Then combining with vector spherical wave functions rotation theory and recursive T matrix algorithm,the scheme can figure out the scattering field of many spheroids in arbitrary orientations.Verifications of the method are provided with numerical examples.
