| 摘 要： | We present a theoretical study of surface Tamm states localized at an interface that separates a semi-infinite isotropic left-handed metamaterial(LHM) and one-dimensional photonic crystal made of anisotropic indefinite metamaterial(IMM)(always-cutoff material).We discuss the dispersion properties of the Tamm states in different bandgaps and demonstrate that the cap layer,angular frequency,and arrangement of photonic crystal can provide flexible control for the dispersive properties of the Tamm states.
