Onsager model for a variable dielectric permittivity near an interface
arXiv:cond-mat/0304087 · doi:10.1080/0026897032000112892
Abstract
Using a generalisation of an Onsager type approach, we are able to predict a dielectric permittivity profile of an inhomogeneous dipolar fluid in the presence of a dielectric interface. The reaction and cavity fields are calculated semi-analytically using bispherical coordinates. An asymptotic expression for the local permittivity is derived as a function of distance from the interface.
