Abstract
We study the out-of-plane photonic band structure of a two dimensional (2D) lattice with pillars made of left-handed material (LHM) or metal embedded in host dielectric. The band structures of 2D photonic crystals made of impedance-matched or impedance-unmatched LHM-RHM elements show resemblance to dielectric-dielectric and metal-dielectric structures, respectively. In particular, lossless LHM-RHM impedance-unmatched lattice supports lossless slow surface modes analogous to lossy modes at a metal-dielectric boundary.
