Abstract

A rigorous theory of emission of an elementary dipole located at the boundary of or within a flat-layered structure has been considered. A method of analytic simplification of the solution has been demonstrated for a particular case of emission of a dipole located on the free boundary of a single film. The proposed method has made it possible to reduce expressions for emitted fields to 1D integrals, which has considerably simplified analysis of the problem and reduced the computation time. As a concrete technical application of the theory, the radiation patterns have been obtained for point emitters (molecules, nanostructures) located on the free surface of a metal film in the Kretschmann configuration, possessing the induced dipole moment directed along the normal to the film surface. The effect of a surface wave on the directional properties of surface emitters has been considered.

平面结构边界上的基本发射器

摘要

已经考虑了位于平面结构边界或平面结构内的基本偶极子发射的严格理论。对于在单个膜的自由边界上的偶极子发射的特殊情况，已经证明了一种解决方案的解析简化方法。所提出的方法使得将发射场的表达式简化为一维积分成为可能，这大大简化了问题分析并减少了计算时间。作为该理论的具体技术应用，已经获得了位于Kretschmann构型的金属膜自由表面上的点发射器（分子，纳米结构）的辐射方向图，该辐射器具有沿膜表面法线定向的感应偶极矩。 。
