Abstract:	摘要： Based on finite difference time domain method, an optical film surface with mixing conical subwavelength structures is numerically investigated to improve antireflection property. The mixing conical subwavelength structure is combined with the pure periodic conical subwavelength structures and the added small conical structures in the gap between the pure periodic conical subwavelength structures. The antireflection properties of two types of subwavelength structures with different aspect ratios in spectral range of 400–800 nm are analyzed and compared. It is shown that, for the mixing type, the average reflectance is decreased and the variances of the reflectance are evidently smaller. When the added structure with a better aspect ratio exists, the average reflectance of the surface can be below 0.30%. Obviously, the antireflection properties of the optical film surface with mixing conical subwavelength structures can be improved. 出版者： Cairo, Egypt: Hindawi Limiteds 出版日期： 2013-01-01 出處： Journal of Nanomaterials, 2013-01, Vol.2013 (2013), p.197-201-221 資源來源： Chinese Electronic Periodical Services (CEPS)_2025 版權： Copyright © 2013 Chi-Feng Chen et al. 識別號： ISSN: 1687-4110 識別號： ISSN: 1687-4129 識別號： EISSN: 1687-4129 識別號： DOI: 10.1155/2013/459325
