- Abstract
- On the basis of the generalized singular approximation a various options of estimates of the effective permittivity of heterogeneous isotropic medium including the Maxwell-Garnett approximation and symmetrical Bruggemans formula are united. Using a differential approach the equation is derived giving new variants of approximation to e* depending on parameter a. These variants of approximation coincide with generalized singular approximation or asymmetrical Bruggemans formula in the limit cases. It is shown that the parameter a is correlated with a dispersion of inclusions sizes in composite.
