Geometric anisotropic effects on local field distribution: Generalized Clausius–Mossotti relation Original Research Article

We have studied the geometric anisotropic effects on the local field distribution by applying the Ewald–Kornfeld formulation to a tetragonal lattice of point dipoles. Discussion on the problems involved in the computation of the conditionally convergent summation of the near field and the methods of overcoming them are given. The numerical results show that the geometric anisotropy has a significant impact on the local field distribution. The change in local field due to geometry anisotropy results in a generalized Clausius–Mossotti equation.
