摘要：We numerically demonstrate an impedance-matched multilayer stacked fishnet metamaterial that has zero index with flat high transmittance from 600nm to 620nm. The effective refractive index(eta(eff)) is calculated to be -0.045 + 0.466i and the normalize effective impedance( Z(eff)/Z(0)) is 0.956-0.368i at 610nm. The light emitted by a red conjugated polymer layer embedded in such a zero index metamaterial (ZIM) is concentrated in a narrow cone in the surrounding media, where the half-power beam width (HPBW) of the center lobe of the radiation pattern is around 25 degrees in the wavelength range between 600nm and 620nm, giving directive emission in the visible region. This proposed light focusing system can be applied to sensing, beam collimating and filtering functionalities. (C) 2014 Optical Society of America
