研究了外电场中一对介质球内外电场的分布规律;得到了外电场中两个介质球存在时的内外电场,研究了相互作用产生的内电场与外电场的方向关系,进一步研究了介电常数、目标距离等对相互作用的影响,结果为多目标的瑞利复合散射特性研究提供了理论支持。
The distributions of inter-electric fields for two dielectric spheres are researched.The expressions of inter-electric fields are presented in the presence of two material spheres at same time.Then the relations between the outside field direction and the inter-field direction induced by the electric interaction are developed.The affects produced by the dielectric constant and the apart distance etc.on the inner fields are further demonstrated.For studying the multi-targets' scattering property,the obtained results may offer a theoretical base.
