中文摘要：

本文通过时域有限差分法求解Maxwell方程组,分析微结构表面与入射辐射间的相互作用,结合近场-远场辐射转换模型,获得了尺寸、温度和入射波长等参数对表面双向反射分布函数的影响规律,研究结果为热辐射的光谱和方向调控技术提供了数值基础。

英文摘要：

The FDTD（Finite Difference Time Domain） method is employed to solve the Maxwell s equations and to analyze the interaction of surface microstructure and incident radiation.Based on the near-to-far field transformation model,the effects of dimension parameters,temperature and incident wavelength on surface BRDF（Bidirectional Reflectance Distribution Function） are obtained. The results offer a numerical foundation to control spectral and directional properties of thermal radiation.
