    "abstract": "We analyze transmission of electromagnetic waves through a periodic band-gap\nstructure consisting of slabs of a left-handed metamaterial and air. Using the\neffective parameters of the metamaterial derived from its microscopic\nstructure, we study, with the help of the transfer-matrix approach and by means\nof the finite-difference-time-domain numerical simulations, the transmission\nproperties of such a left-handed photonic crystals in a novel type of band gap\nassociated with the zero averaged refractive index. We demonstrate that the\ntransmission can be made tunable by introducing defects, which allow to access\nselectively two different types of band gaps.",
