Analog of TAMM state in planar photonic crystal, bounded by the plasma-like medium

The term “Tamm states” arose from the famous work of Igor Tamm, who predicted the appearance of surface states at the boundary of periodic crystal lattice. Later the term was widely used for theoretical description of electromagnetic wave propagation in bounded one-dimensional photonic crystals (PCs). As it is known, PCs are also periodic structures consisting (for example) of layers with different permittivity. In the case when the periodic structure (the PC) is bounded by the metal-like medium (wire-medium or some other media in which electromagnetic waves cannot propagate due to the strong attenuation) electromagnetic surface Tamm states appear at the interface.
