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 parametexs, 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.
