英文摘要 | Antireflection structured surface was analyzed by a finite difference time domain (FDTD) method in the visible light spectrum. The antireflection structured array was conical moth-eye structures. Comparing the reflectance of different aspect ratios by the FDTD method, we found that the reflectance was less than 1% when the aspect ratio was larger than 0.8 in the visible light spectrum. In order to confirm the results by this simulation method, the conical structured arrays of a polymer film were fabricated by the holographic lithography and a following replicating process. The conical structured arrays were fabricated with the periodic length of 350 nm and the height of 300 nm. The simulation results by FDTD method were compared with those by the fabricated sub-wavelength structures. The experimental results showed highly consistent with the simulation results. |
