| Abstract: | 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. |
