倏逝光子与环境的相互作用
Interactions Between Evanescent Photons and Environment
摘要：
命名为EW 1，EW 2，EW 3的倏逝波在3个相应的实验设置中描述：1）全内反射; 2）在非均匀平面目标上的散射;以及3）沿波导的传播。EW 2和环境之间的一些相互作用被认为是。后者可以包括探测粒子束和/或在其上形成EW 2的屏幕。描述了电磁波的一些新性质，如可动屏情况下的复能量本征值，以及相互作用物体之间的倏逝光交换。这揭示了所研究系统的倏逝态和伽莫夫态之间的联系。EW 2和探针之间的4-动量交换是高度选择性的，并且可以将所研究的EW 2-本征态的叠加坍缩为探测粒子的单个EW-本征态。简要讨论了EW 2在远场可能的印记，并提出了一个简单的实验观察。.
英文摘要：
The evanescent waves named as EW1, EW2, EW3 are described in 3 respective experimental setups: 1) total internal reflection; 2) scattering on an inhomogeneous planar target; and 3) propagation along a waveguide. Some interactions are considered between EW2 and the environment. The latter may include a beam of probing particles and/or the screen on which the EW2 are formed. Some new properties of EW are described, such as complex energy eigenvalues in case of a movable screen, and evanescence exchange between the interacting objects. This reveals the connection between evanescent states and the Gamow states of the studied system. The 4-momentum exchange between EW2 and the probe is highly selective and may collapse the superposition of studied EW2- eigenstates to a single EW-eigenstate of the probing particle. Possible imprints of EW2 in the far field are briefly discussed and a simple experiment is suggested for their observation. .
