The Electromagnetic response of two-dimensional Gratings of dielectric and magnetic fibers : Infinite and finite cases

The last few years have seen a growing interest in the analysis of heterogeneous materials. These investigations lead to many applications as for example the development of absorbing materials or frequency selective surfaces. To the diversity of the applications corresponds a variety of approaches used in the modeling of the fields scattered by heterogeneous materials. We have mainly investigated the case of 2D gratings of dielectric and magnetic fibers embedded in a multilayered medium placed or not over a perfectly conducting plane.
