Abstract

In this paper, genetic evolutional algorithm is used for getting material parameters of absorbing structures. Reflection coefficients are measured by system based on free-space method. For improving precision, normal distributed random variable is used in genetic evolutional algorithm. By this method, the parameters of the unknown layer can be gotten from absorbing structure effectively. This method can solve multi-values problems brought from traditional transmission line method
