Effective medium theory

The different effective medium theories available on the market have all the same origin, i. The Maxwell Garnett and Bruggeman effective medium theories are derived for the. The derived effective medium theory not only recovers the. Originally developed to estimate transport coefficients, this theory is based on the idea of replacing the inhomogeneous medium by an equivalent homogenous . The approach leads to exact formulas for the effective .
