To improve the FEM parameter set, further investigations are needed into other, nonellipsoidal representations for anisotropic particles embedded in matrix. A more general mapping of the atomistic interface onto the interfacial layer of the FEM is also being examined for model improvement. Additionally, a broader set of systems, including other matrix and inclusion materials, are currently being considered, in order to generalize the FEM implementation for an array of currently relevant dielectric ceramics with highly-polarizable inclusions.
