The generalized Kirchhoff's law(Rytov theory) predicts that the polarization state of thermal emission from an individual small particle depends on the particle shape. We show for the first time experimental evidence confirming this prediction for particles smaller than the wavelength. We propose that the measurement of the polarization state of thermal emission may be applicable to real-time analysis of the shape of black carbon particles in air.

广义基尔霍夫定律（Rytov理论）预测，来自单个小颗粒的热发射的偏振状态取决于颗粒形状。我们首次展示了实验证据，证实了小于波长的粒子的这一预测。我们建议，热发射偏振态的测量可能适用于实时分析的形状的黑碳颗粒在空气中。
