APPROXIMATE CALCULATION METHODS OF CONDUCTIVITY IN INHOMOGENEOUS SYSTEM.
Abstract
Developed a general theoretical method for calculating the conductivity for a
wide class of physical, geophysical and biological heterogeneous systems. It is
believed that in such systems heterogeneity placed randomly, and the size of
heterogeneities is much smaller than the wavelength of the AC electric field, in
which the system being studied. It is shown that finding an effective conductivity of
such systems is reduced to the solution of the integral equation. Developed two
approximations of the solution: method averaged T-matrix method and the coherent
potential. The analysis and comparison of the accuracy of these methods.
