Abstract

A rigorous theory of radiation of an elementary dipole that is located either on the boundary of a plane-layered structure or inside it is considered. For a particular case of radiation from a dipole located on a free boundary of one film, a method of analytical simplification of the solution is demonstrated. This method has made it possible to reduce the formulas for emitted fields to one-dimensional integrals, which greatly simplified the analysis of the problem and speeded up numerical calculations. As a specific technical application of the theory, directional patterns of point emitters (molecules, nanostructures) located on the free surface of a metal film in the Kretschmann scheme and having an induced dipole moment along the film surface have been obtained. The influence of the surface wave on the directional properties of emitters has been determined.

位于层状结构边界上或内部的基本偶极发射极

摘要

考虑了一个严格的关于偶极子辐射的理论，该偶极子位于平面分层结构的边界上或内部。对于来自位于膜的自由边界上的偶极子辐射的特定情况，证明了一种解决方案的分析简化方法。这种方法可以将发射场的公式简化为一维积分，从而大大简化了问题分析并加快了数值计算的速度。作为该理论的特定技术应用，已经获得了在Kretschmann方案中位于金属膜的自由表面上并沿膜表面具有感应偶极矩的点发射器（分子，纳米结构）的方向图。
