Abstract: We used two novel approaches to produce sub-wavelength structure anti-reflection coatings on silicon for millimeter and sub-millimeter wave bands: picosecond laser ablation and dicing with beveled saws. We produced pyramidal structures with both techniques. The… read more here.

Abstract: TiO2/SiO2 multilayer structures, have demonstrated reflectance exceeding 90% in the visible spectrum (500–600nm) and a contact angle of 45°, indicating strong hydrophilic self-cleaning properties. These coatings exhibit well-defined multilayers, with precise thickness control (~100–120 nm… read more here.
