In this work, a dielectric at a finite temperature is modeled as an ensemble of identical atoms moving randomly around where they are trapped. Light reflection from the dielectric is then discussed in terms of atomic radiation. Specific calculation demonstrates that because of the atoms' thermal motion, Brewster's angle is, in principle, temperature-dependent, and the dependence is weak in the low-temperature limit. What is also found is that the Brewster's angle is nothing but a result of destructive superposition of electromagnetic radiation from the atoms.
在这项工作中，处于有限温度的电介质被建模为被困在各自位置周围随机移动的相同原子的集合。然后根据原子辐射来讨论从该电介质的光反射。具体计算表明，由于原子的热运动，布儒斯特角原则上与温度有关，并且在低温极限下这种相关性较弱。还发现布儒斯特角只不过是来自原子的电磁辐射相消叠加的结果。
