在考虑非平衡电子动力学和热化过程的等离子体压力机制框架下，从理论上讨论了等离子体材料中轻物质的动量转移。我们表明，我们的方法解释了实验观察到的等离子体激元相关的电动势和吸收之间的关系，并允许一个正确的预测等离子体激元的阻力电动势在平坦的金属薄膜的大小。我们将我们的理论扩展到具有调制轮廓的金属膜，并表明等离子体激元能量和动量转移之间的简单关系在相对较小的高度调制幅度和层流电子漂移近似下成立。为进一步研究纳米结构金属中形状控制的等离子体激元拖曳奠定了理论基础。
Light-matter momentum transfer in plasmonic materials is theoretically discussed in the framework of plasmonic pressure mechanism taking into account non-equilibrium electron dynamics and thermalization process. We show that our approach explains the experimentally observed relationship between the plasmon-related electromotive force and absorption and allows one to correctly predict the magnitude of the plasmon drag emf in flat metal films. We extend our theory to metal films with modulated profiles and show that the simple relationship between plasmonic energy and momentum transfer holds at relatively small amplitudes of height modulation and an approximation of laminar electron drift. Theoretical groundwork is laid for further investigations of shape-controlled plasmon drag in nanostructured metal.
