In the current work we introduce a finite-element method (FEM) for calculating the effective permittivity of macroscopically inhomogeneous media. Specifically, we consider two-dimensional (2d) two-phase heterostructures consisting of hard circular disk equilibrated distributions.
The hard-disk distribution has been chosen as the reference system since it is one of the simplest idealized models to explain structural and kinetic properties of matter, e.g. disk configurations in the plane have been advanced as a simple model for the arrangements of particles adsorbed on smooth surfaces.
