Abstract :
The polarization (TE or TM) of the electromagnetic field controls the dielectric response of an anisotropic periodic structure composed of successive layers with either negative permeability or negative permittivity. In a certain range of frequencies and incidence angles the periodic structure can thus behave as a metamaterial (left-handed material) for one polarization and as a right-handed material for the other polarization.
