Abstract: To investigate metal dielectric constant influence on optical Tamm state, complex refractive index in three dispersion models is studied. TE wave and TM wave of optical Tamm state with different incident angle and silver layer thickness and cycles number are studied in silver-photonic crystal-silver structure. Two optical Tamm state appeare (OTS1 and OTS2). In three dispersion models wavelength of optical Tamm state changing with incident angle and silver layer thickness and cycles number are similar. Transmission peak of optical Tamm state changing with incident angle and silver layer thickness and cycles number are different. Drude-Lorentz model and Lorentz model can describe characteristics of silver, but the Drude model can't.

Key words: photonic crystal, optical Tamm state, Drude-Lorentz model, Lorentz model, Drude model
