Comprehensive study of chirality through simulation of double-layer elliptical nano-holes
Abstract:
In this study, we propose a double-layer elliptical nanohole array (DLEN) and investigate its chiral properties using the finite element method. The DLEN structure simultaneously exhibited asymmetric reflection (AR), circular dichroism (CD), and asymmetric transmission (AT) effects with specific measured values. By analyzing the full cycle of plasmon resonance modes, we identified that the local rotational resonance excited by circular polarized light (CPL) is important in the conversion of right circularly polarized (RCP) and left circularly polarized (LCP) light upon reflection and transmission. Furthermore, we address and refine the theoretical models and simulation conclusions from previous studies. This study offers effective methods for precisely investigating chirality and may improve the efficiency of future research.
