-Textured coatings have antireflective properties for wavelengths much smaller then texture size as well.+Textured coatings have antireflective properties for wavelengths much smaller than texture size as well.
 In this case reflection reduction can be illustrated geometrically: rays should be reflected many times until being reverted back.  In this case reflection reduction can be illustrated geometrically: rays should be reflected many times until being reverted back. 
 At the same time transmitted rays deviate from the incident direction that leads to light trapping effect used in solar cells.  At the same time transmitted rays deviate from the incident direction that leads to light trapping effect used in solar cells.
