Abstract

A numerical procedure for solving the effective medium approximation equations for ellipsometric data analysis is presented. The idea is to transform the complex root-finding problem into a minimization task in real space. Thus, the method can be implemented through a standard downhill simplex algorithm, leading to a general, simple and useful technique for ellipsometric developments.
