标题： Enhancement of Resonant Energy Transfer Due to Evanescent-wave from the Metal

摘要： 金属附近倏逝模的高密度导致近场福勒-雷斯尼克共振能量转移（FRET）速率增强。 我们提出一种经典方法，基于任意介质环境的二阶格林函数来计算FRET速率，并在金属半空间和薄层情况下考虑材料介电常数的非局部极限。 在二聚体系统中，我们发现由于连接供体和受体的共享倏逝光子模式，FRET速率得到增强。 此外，推导了多聚体系统的FRET速率的一般表达式。 介电环境的存在和路径干涉效应会根据距离和几何结构的组合增强转移速率。 显示英文摘要

摘要： The high density of evanescent modes in the vicinity of a metal leads to enhancement of the near-field F\"{o}rster resonant energy transfer (FRET) rate. We present a classical approach to calculate the FRET rate based on the dyadic Green's function of an arbitrary dielectric environment, and consider non-local limit of material permittivity in case of metallic halfspace and thin film. In a dimer system, we find that the FRET rate is enhanced due to shared evanescent photon modes bridging a donor and an acceptor. Furthermore, a general expression for the FRET rate for multimer systems is derived. The presence of a dielectric environment and the path interference effect enhance the transfer rate, depending on the combination of distance and geometry.
