| 目的 研究自然界中结构色呈色的不同机理和光栅微结构的反射或透射光呈色的特点。方法 运用时域有限差分法 （FDTD） 理论， 以FDTD Solutions和Matlab为平台， 建立2种周期性光栅结构仿真模型（对称仿生结构模型和非对称仿生结构模型）， 并利用颜色理论研究其结构色呈色原理。结果 获得了2种光栅反射光谱特性曲线颜色及其差异。结论 周期性光栅微结构可以创建光谱颜色， 结构模型参数发生变化的峰值位置出现了明显偏离现象， 颜色光从非对称仿生结构模型的蓝色光 （光谱波峰值为455nm）， 变为对称仿生结构模型的绿色光 （光谱波峰值为550 nm）， 为制造颜色特性可控的人造结构色和光栅结构色呈色规律提供更多理论依据。 |

| The purpose of this work was to study the different mechanisms of coloring of structural color and the color rendering characteristics of the reflection or transmitted light of the grating microstructure. Using FDTD Solutions and Matlab as the platform, FDTD (finite difference time domain method) theory was employed to establish a two-cycle the simulation model of the grating structure: symmetrical and asymmetrical structure model bionic structure model to study the structure of color theory using color theory. The reflection grating spectral characteristics of the two curves and color differences were obtained. In conclusion, periodic grating microstructures could create spectral color, apparent deviation occurred at the peak position of the change of the structural model parameters, the color of light changed from asymmetric bionic structure model blue light (spectral wave peak at 455 nm) to symmetric bionic structure model green light (spectral wave peak at 550 nm), providing more theoretical basis for the manufacture of artificial structures with controllable color characteristic color and coloration law of grating structural color. |
