A novel computer simulation method is presented for the non-dissipative dielectric response of binary mixtures. It is based on the discretization of Maxwell's equations and thus takes into account all classical long-range interactions between different particles implicitly. The simulations performed yield a relationship between the dielectric functions of the two components, the volume fraction and the dielectric function of the mixture, which can be described by an exponential formula. It was found that the exponent in this formula depends on the volume fraction but not on the dielectric properties of each component. The mixture rule is in agreement with experimental data taken from literature.
