摘要
利用闭合轨道理论,对原子在界面附近的自发辐射率的计算公式进行了推导,并对界面附近原子自发辐射率的多周期振荡现象进行了系统的研究.首先,根据光子的闭合轨道理论,把原子的自发辐射用经典的偶极天线辐射来模拟,推导出原子在一个金属界面旁的自发辐射率的计算公式,然后再推广到两个金属界面旁的原子自发辐射情况,并对原子自发辐射率的多周期振荡进行了分析.
We derived the formula of the spontaneous emission rate of atoms near the interfaces and discussed the multi-periodic oscillating phenomenon of the atoms near the interfaces. First of all, according to the photon closed-orbit theory, we simulated the spontaneous emission of atom near interface as the radiation of the classic dipole antenna, then we derived the calculation for- mula of the spontaneous emission of atom near a metal surface. Next, we developed this case to the spontaneous emission of atom near two metal surfaces, and analyzed the multi-periodic oscil- lating phenomenon appeared in the spontaneous emission rate of atom near two metal surfaces.
