meta nanopillar array
We report the extraordinary light harvesting property of a metamaterial-based subwavelength
nanopillar array with a periodic arrangement. It is found that the meta-nanopillar array can
absorb light efficiently with an average absorptivity of 0.96 over the whole visible waveband
with independent of the incoming light polarization state as well as the wide receiving angle of
as large as660
. We attribute the efficient light harvesting property of meta-nanopillar array
to the synergistic effect of the slow light mode and localized surface plasmon resonant effect.
