研究了具有不完全间隙的光子晶体中原子的衰变和辐射。如果过渡频率接近带边缘，则 Weisskopf-Wigner 近似不适用并且衰减是非指数的。自发射场可以大大增强或减少衰减。
The decay and radiation of an atom in a photonic crystal with an incomplete gap was investigated. If the transition frequency is close to a band edge, the Weisskopf-Wigner approximation is not applicable and the decay is nonexponential. The decay could be greatly enhanced or decreased by the self-emitted field.
