| Abstract: | By using the strong fluctuation theory and introducing an auxiliary permittivity, the effective permittivity can be derived, and is applied to the calculation of effective conductivity of composite material embedded by dense conducting and non-spherical particles. Numerical results for the functional dependence on fractional volume, correlation length, and frequency are presented.It can be seen that the composited material embedded by dense conducting and non-spherical particles has anisotropic effective conductivity and different conductivity transfer. |
