TITLEPhotonic band engineering in one-dimensional left-handed metamaterials

ABSTRACTOne-dimensional left-handed metamaterials based on interleaved split ring resonators and complementary split ring resonators are proposed and analyzed experimentally. The electromagnetic wave propagation has a negative phase velocity and a very slow group velocity, down to 0.01 of the light speed in free space. By changing the ring orientations, the inversion symmetry can be broken and a photonic band gap appears in the passband. The single passband and split pass bands conditions are systematically studied by simulations. Finally, the possible orientation texture in a two-dimensional array leading to exotic phenomena, such as artificial gauge field will be addressed.
