中文摘要：

利用传输矩阵方法讨论了光子晶体对大气窗口波段发射辐射的抑制作用,讨论了多种基底材料和光子晶体材料组合及其自发辐射对抑制效果的影响。研究发现,当光子晶体的高低折射率介质分别为Si与KCl时,在3～5μm与8～14μm波段内,基底分别处于100℃的Al、SiC及假想表面,表面的发射辐射均可得到较好地抑制。对于相同基底,选择Ge与KCl作为光子晶体的组成材料,会有更好地抑制效果。

英文摘要：

The transfer matrix method was used to analyze the suppression effect of photonic crystals on atmospheric window band emission. Several combinations of substrates and photonic crystals and suppression effects of their spontaneous radiation were discussed. It is found that,when the photonic crystals are made of media of Si and KCl with high and low refractivities,and the substrates are Al,SiC and imaginary surface at 100 ℃ respectively,all the surface emissions are suppressed well in the ranges of 3 ～ 5 μm and 8 ～ 14 μm. For the same substrate,it can suppress the emissions better,if Ge and KCl are chosen as the composition materials of photonic crystals.
