Abstract :
Multilayered structures known as photonic crystals are object of many researches lately. Some special Photonic Crystals, containing magnetic layers and misaligned anisotropic dielectric layers, show an asymmetric dispersion relation. These structures are referred as magnetic photonic crystals (MPC). The asymmetric dispersion relation can be associated with the electromagnetic unidirectionality. A unidirectional medium "freezes" the radiation of certain frequency and direction (frozen mode), being perfectly transparent for the wave with the same frequency and the opposite direction. Using the transfer matrix method, we study the influence of various physical and geometrical parameters on the frozen modes of magnetic photonic crystals.
