Autor: Brahim Essakhi, Ouail Ouchetto

Publikováno v: Waves in Random and Complex Media. 28:523-532

In this paper, we present a new method for homogenizing the bi-periodic materials with bi-isotropic components phases. The presented method is a numerical method based on the finite element method to compute the local electromagnetic properties. The
