周期多层膜X射线驻波增强荧光的振荡偶极子模型
Oscillating dipole model for the X-ray standing wave enhanced fluorescence in periodic multilayers
摘要：
当结构内出现驻波时，周期性多层膜产生增强的X射线荧光。该机制可能涉及用于诱导荧光的初级辐射、荧光的次级辐射或两者。到目前为止，现有的模型只处理初级辐射的驻波区。我们提出了一个理论方法的基础上振荡偶极子模型和耦合波理论，可以有效地处理任何驻波制度。我们比较我们的模拟文献中的实验数据。
英文摘要：
Periodic multilayers give rise to enhanced X-ray fluorescence when a regime of standing waves occurs within the structure. This regime may concern the primary radiation used to induce the fluorescence, the secondary radiation of fluorescence or both of them. Until now, existing models only dealt with standing wave regime of primary radiation. We present a theoretical approach based on the oscillating dipole model and the coupled-wave theory that can treat efficiently any standing wave regime. We compare our simulations to experimental data available in the literature.
