We consider a generalization of the effective medium approximation to the case of matrices containing macroscopically inhomogeneous particles with an arbitrary structure (cermet topology). The form of the result is determined to a considerable extent by the heuristic choice of effective cells used to estimate the field and induction values averaged over the volume. The simplest choice of a particle...
Depolarization factors for an anisotropic ellipsoid in an anisotropic medium are defined. It is shown that conventional depolarization factors, which are valid for isotropic media, can be extended to anisotropic media by introducing the concept of “reduced ellipsoid,” in which the anisotropy of the ellipsoid shape, as well as anisotropy of the medium, is taken into account.
