Abstract :
We use the simulated annealing (SA) method to find the global minimum of a cost function associated with scattering from a layered dielectric structure with rough boundaries. In the case of a two layer structure, even a simple implementation of the SA algorithm is capable of retrieving more parameters than is possible with local optimization methods. We discuss different strategies that can improve the performance of this algorithm for our purpose.
