The field redistribution inside an X-ray cavity-QED setup with an embedded Fe layer is calculated and studied in detail. The destructive interference between two transitions from the ground state to the two upper dressed states causes that the cavity mode can not be driven. So the field intensity is very weak when the nuclear ensemble is resonant. Moreover, It is found that the resonant nuclear layer can play a role of reflective layer like a mirror and cut the size of the cavity, which will destroy the guided mode. To support this idea, we employ the Fe film as the bottom mirror layer of the cavity where a guided mode can only be formed at the resonant energy. Following this perspective, the electromagnetically induced transparency structure based on X-ray cavity-QED setup with nuclear ensemble is reviewed and a phenomenologically self-consistent analysis for the field redistribution is presented.
详细计算并研究了具有嵌入式铁层的X射线腔量子电动力学装置内部的场再分布。从基态到两个上 dressed 态的两个跃迁之间的相消干涉导致腔模无法被驱动。因此，当核系综共振时，场强非常弱。此外，发现共振核层可以像镜子一样起到反射层的作用并减小腔的尺寸，这将破坏导模。为了支持这一观点，我们使用铁膜作为腔的底部镜层，在共振能量处只能形成一个导模。基于这一观点，回顾了基于具有核系综的X射线腔量子电动力学装置的电磁诱导透明结构，并给出了场再分布的唯象自洽分析。
