Abstract

In this paper, windmill-shaped planar structure arrays operating in the mid-IR regime are proposed. Strong chiral dichroism of windmill-shaped planar structure is obtained numerically. The dependence of spectral characteristics on the geometrical parameters of the windmill-shaped planar structure is analyzed by the finite-difference time-domain (FDTD) method. The chiroptical near-field response of windmill-shaped planar structure arrays is also determined. Furthermore, potential applications of the proposed windmill-shaped planar structure due to its enhanced near-field chiroptical response and tunable characteristics are discussed.
