Abstract

A kind of subwavelength structure array is numerically investigated to improved antireflection property. Based on finite difference time domain method, we consider adding a small conical structure in the gap between the pure periodic conical subwavelength structure to analylz the antireflection property in spectral range of 400-1100 nm. The improved antireflection property of subwavelength structures have distinguishing characteristic in particular places. The result shows the morphological effect on reflectance of new conical shape subwavelength structures.
