Calculating Effective Dielectric Constant of Composite Dielectric Material

We present a simple and efficient approach to calculate the effective dielectric constant of a composite material using equivalent circuit of its unit cell in this article. The equivalent capacitors model of a unit cell is used for the approximation of any number of inclusions of any shape using this method. The method's calculation process involves basic matrix operations to implement with different commercial or free software and programming languages. The comparison with other approaches as well as experimental results is presented, too.
