Abstract:

本文研究了环境湿度变化与二维光子晶体禁带的关系，环境湿度变化导致二维光子晶体介质折射率发生变化，二维光子晶体介质的折射率变化将导致其光子能带结构的变化。本文对二维光子晶体光学湿敏特性进行研究，为湿度检测与控制提供一个更为节能、便捷的技术手段。
The purpose of this paper is to study the relationship between the change of environmental hu-midity and the forbidden band of two-dimensional photonic crystal. The change of ambient hu-midity causes the refractive index of the medium to change. The medium with different refractive indices constitutes a photonic crystal with different properties, that is, the photonic band structure of two-dimensional photonic crystal makes difference. Through continuous data simulation and simulation of its internal relationship, a system model for two-dimensional photonic crystal humidity measurement is designed. It provides a more energy-saving and convenient technical means for people to detect and control humidity in production and living environment.
