【Abstract】 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.更多还原
