What Does FMIR Stand For?

FMIR stands for Frustrated Multiple Internal Reflection

FMIR, or Frustrated Multiple Internal Reflection, is an optical phenomenon that occurs when light encounters a medium boundary at an angle that leads to partial reflection and transmission. This effect is characterized by multiple internal reflections within a material, often enhanced by surface modifications or geometric configurations. FMIR is utilized in various applications, including sensor design, optical coatings, and photonic devices, where it can improve signal characteristics and enhance light-matter interactions.
