摘要
Abstract
Subwavelength periodic structure on infrared material can achieve antirefiective function at infrared band. In harsh environment, infrared window may replace infrared antireflective film. And it can provide corrosion resistance, shock resistance, etc. This paper describe the design of subwavelength relief unit structure using effective medium theory, and fabrication of the relief structure on the surface of sapphire material by photolithograph and ion etching. The infrared transmittance improved about 10 percent. The relation of antireflective and Periodic, filling cycle, and unit depth etc are analyzed.关键词
