Abstract
Herein, we propose a special type of periodic subwavelength structure, which is optically an effective gradient-index (GRIN) antireflective surface that also exhibits enhanced-hydrophobic behaviour.Our new concept was developed adopting both the effective medium theory (EMT) and Wenzel's wettability model.To demonstrate the concept, an inverted pyramid structure was fabricated by electron beam (EB) lithography and anisotropic etching.The experimental data was found to be in good agreement with the theoretical prediction.Some potential applications that can benefit from this combination of antireflection and enhanced-hydrophobicity features are discussed.
