The method was applied to modeling the dielectric response of metal-oxide matrix materials and noble metal nanoparticle inclusions. The addition of 8-atom silver nanoparticles to the magnesium oxide matrix increased the permittivity by up to 30 % for atomic loadings of 3.7 % Ag. Larger, anisotropic inclusions led to further increases in permittivity, at similar loadings. These increases were attributed to both the high polarizabilities of the inclusions, and the increased polarizabilities of matrix ions near the inclusions, due to greater electron delocalization -a quantum effect. While elegant, this method is computationally expensive.
