WebAug 30, 2024 · Specifically, Díaz León said, by using the solar spectrum as a target, the researchers learned that regular micro-scale pyramidal structures largely reduce specular reflectance -- the mirror-like reflectance found in polished surfaces -- whereas the small nanometer-scale structures reduce diffuse reflectance, which consists of reflections ... Web反射率（英語： Reflectivity 或 Reflectance ）是在一个界面反射中，反射波與入射波功率的比值。 注意，它不等同于反射系数（英語： Reflection coefficient ），反射系数定义为电磁波反射波与入射波的振幅比 。. 参考文献

WebDec 6, 2016 · Reflectivity is the capacity of an object to reflect solar radiation. It is described as a function of radiation wavelength and is determined by the physical composition of … WebAnti-reflection V-coats are a type of AR coating designed to increase transmission over a very narrow waveband centered at a specified design wavelength (DWL). This coating type is called “V-coat” because the curve of the transmission versus wavelength forms a “V,” with a minimum at the DWL. V-coats are ideal for obtaining maximum ...
