Effective-Medium Approach for Composite Materials Containing Conductive Sticks

There is a growing interest in composites in which conductive component has the elongated shape (sticks) because these systems can be used to describe various physical objects [1]. The main tool to investigate the systems is MC simulation. For example in papers [2-4] the percolation threshold in such systems has been explored and it was obtained that pcα r/L, where r is the radius of stick and L is it's length. In this work, we are suggest the calculation of dielectric constant and conductivity method based on effective medium approximation.
