摘要

结果表明，在纳米尺度的介质球中，局部电场并不像宏观平均场理论所期望的那样均匀。本文提出了一种能够对这些局部场进行微观计算的数值方法。结果表明，对于大直径，微观计算趋向于宏观理论。

Local Field versus Meanfield Theory for Dielectric Spheres

It is shown that the local electric field in a dielectric sphere of nanometric dimensions is not uniform as expected from macroscopic meanfield theory. A numerical method is presented which allows the microscopic calculation of these local fields. It is shown that for large diameters the microscopic calculations converge towards the macroscopic theory.
