Abstract
Based on the hydrodynamical model, we develop a transfer matrix formalism to study the optical properties of a superlattice which is composed of two alternating conducting slabs and is subjected to an external static magnetic field parallel to the interfaces. The retardation and collisional damping effects are taken into account. We present the dispersion relations of the electromagnetic modes for an infinite periodic structure and calculate the reflection spectra for a finite system. The localization of the polaritons in a quasi-periodic multilayers is discussed by plotting the amplitudes of the electric field. We find that the dispersion relations are obviously modified by the external magnetic field, and the reflection spectra show rich structure when the magnetic field is applied. The spectra of the electromagnetic modes for the quasi-periodic multilayers exhibit a Cantor-like structure with a scaling property. A transition of extended states to localized states is possible when we vary the applied magnetic field.
