具有非常短的长度和平面平行介电镜的模型腔中的自发发射是在微扰近似下通过量子力学计算的。考虑输出模式和引导模式。将方向性和发射到外层空间的速率的结果与 Purcell 方法的估计值进行了比较。这就引出了“腔模”的“有效面积”的概念，它具有简单的物理解释。
Spontaneous emission in a model cavity with very short length and with plane-parallel dielectric mirrors is calculated quantum-mechanically under perturbation approximation. Outgoing modes as well as guided modes are considered. Results on the directivity and the rate of emission into outer space are compared with the estimate by Purcell's method. This leads to the concept of "effective area" of the "cavity mode", which has a simpie physical interpretation.
