我们提出了位于平面金属镜上的分子阵列之间的F\'orster能量转移理论。首先，我们计算了光耦合供体分子的集体布洛赫模式的复杂能带结构。接下来，我们确定了从供体到受体的能量转移的有效速率，并揭示了镜子对其的强烈修改。根据受体和供体阵列之间的相对位置，该速率可以被抑制或增强。传输速率的强修改是一种集体效应，由之间的耦合介导。捐助者；它在单一捐助者模型中不存在。
We present a theory of F\"orster energy transfer between arrays of molecules lying on the planar metallic mirror. First, we calculate the complex band structure of the collective Bloch modes of the light-coupled donor molecules. Next, we determine the effective rate of the energy transfer from the donors to the acceptors and reveal its strong modification by the mirror. The rate can be either suppressed or enhanced depending on the relative positions between the acceptor and donor arrays. The strong modification of the transfer rate is a collective effect, mediated by the coupling between the donors; it is absent in the single-donor model.
