| The properties of electromagnetic waves in two dimensional periodic structures created by alternating metal and dielectric layers are investigated. The structure is assumed to be finite in the direction normal to the layers and infinite in other directions. Dispersion relations for both TE- and TM polarized eigenmodes of metal-dielectric superlattice have been analyzed. It is demonstrated that the dispersion show typical properties of optic Tamm states. |
