1. A thin-film structure comprising:

  • a base on which is disposed a plurality of parallel line-shaped corrugated structures;

    a plurality of parallel plate-shaped metals provided on said base, said plate-shaped metals being disposed at a fixed angle with a surface of said base, and an end of each plate-shaped metal being in contact with said base along the direction of said line-shaped corrugated structure, wherein an average gap (d) between said plate-shaped metals, a film thickness (H), and an average width (W), in terms of a working wavelength λ

    , and an angle (θ

    ) relative to said base lie within the following ranges;
