Abstract

The dipole approximation was a widely adopted approach in the effective solution in the local electric field of the particle system, it has a high accuracy in calculating the local electric field of the single particle system. But when the distance between the two particles is small, the interaction between the two particles causes large errors on the calculation in local electric field via the dipole model. Moreover, the higher-multipole model requires repeatedly superimposed calculation, which makes the calculation process more complicated. Therefore, in this paper, a mutual-coupling dipole model is proposed. The electric field distribution of the two-sphere system calculated based on this model is compared with the results based on the finite-element method. The results show that the model is effective in calculating the electric field distribution of the two-sphere system. The model is also effective for calculating the electric field distribution of multi-sphere systems.

考虑粒子间相互作用的电场分布计算方法

偶极子近似是粒子系统局域电场有效解中广泛采用的一种方法，它在计算单粒子系统局域电场时具有较高的精度。但当两粒子之间的距离较小时，两粒子之间的相互作用会导致偶极子模型计算局域电场的误差较大。此外，高多极模型需要多次叠加计算，使得计算过程更加复杂。因此，本文提出了一种相互耦合的偶极子模型。将基于该模型计算的双球系统电场分布与基于有限元法计算的结果进行了比较。结果表明，该模型可以有效地计算两球系统的电场分布。该模型也适用于多球系统的电场分布计算。
