本文用麦克斯韦方程组求解了由位于层状系统中的振荡点偶极子组成的源的辐射。解决方案开发的第一个相关的问题，在系统中产生的领域由一个遥远的偶极子源，和感兴趣的问题，然后解决应用洛伦兹互易定理。极薄的层的影响被认为是详细的。通过计算位于平面束缚银金属衬底上的薄膜中或附近的偶极子的发射，说明了一些结果。结果发现，吸收，发射，或拉曼散射的表面选择规则是无效的分子包含在这一膜。
Maxwell’s equations are solved for the radiation due to a source consisting of an oscillating point dipole located in a layered system. Solutions are developed first for the related problem of the fields generated in the system by a distant dipole source, and the problem of interest is then solved by application of the Lorentz reciprocity theorem. The effects of extremely thin layers are considered in detail. Some of the results are illustrated by calculations of the emission from dipoles located in, or near, a film covering a plane‐bounded silver metal substrate. It is found that the surface selection rule for absorption, emission, or Raman scattering is not valid for molecules contained in this film.
