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.
