Liquid Crystal Infiltrated Optical Magnetic Metamaterials

We study both experimentally and numerically the electric tunability of optical split-ring-resonator metamaterials infiltrated with liquid crystals. By examining the shift of the observed Fabry-P ` fringes and the metamaterial resonances, we show that the liquid crystal molecular anchoring to the nanoscale split-ring-resonator meta-atoms plays an important role in determining their tunability and optical properties.
