    "abstract": "We present a theoretical study of electromagnetic surface waves localized at\nan interface separating a conventional uniform medium and a semi-infinite 1-D\nphotonic crystal made of alternate left-handed metamaterial and right-handed\nmaterial which we refer to as left-handed photonic crystal. We find novel type\nof surface mode\u0027s structure, the so-called surface Tamm states and demonstrate\nthat the presence of metamaterial in the photonic crystal structure allows for\na flexible control of the dispersion properties of surface states, and can\nsupport the Tamm states with a backward energy flow and a vortex-like\nstructure.",
