A classical simulation of equilibrium thermal emissivity from dispersive, lossy photonic crystals is presented. Normal emission results consistent with those assuming Kirchoff's law are obtained; i.e., a photonic crystal does not emit more than what a blackbody does. Significant enhancement, however, can be achieved over the radiation intensity from a uniform slab, indicating the potential usefulness of photonic crystals in incandescent lighting and thermal photovoltaic applications.
本文给出了对色散、有损耗光子晶体平衡热发射率的经典模拟。得到了与假设基尔霍夫定律相符的法向发射结果;即,光子晶体的发射不会超过黑体的发射。然而,与均匀平板的辐射强度相比,可以实现显著增强,这表明光子晶体在白炽灯照明和热光伏应用中的潜在用途。
