在简要概述了纳米等离子体激元实验，违背经典电动力学的解释，我们介绍了非局部响应的非经典效应的主要原因。这个概念首先介绍唯象，后来的基础上半经典的流体动力学Drude模型（HDM），确实表现出非局部响应。特别是，我们讨论了最近的推广和扩展的HDM，包括对流和扩散动力学的感应电荷。这种广义的非局部光学响应（GNOR）模型允许第一次统一的半经典解释已知的实验现象的单体和二聚体，以前似乎需要微观理论。最后，我们转向朗道阻尼和讨论的GNOR模型中的经典扩散机制捕获的尺寸依赖阻尼的微观起源。
After a brief overview of nanoplasmonics experiments that defy explanation with classical electrodynamics, we introduce nonlocal response as a main reason for non-classical effects. This concept is first introduced phenomenologically, and afterwards based on the semi-classical hydrodynamic Drude model (HDM) that indeed exhibits nonlocal response. In particular, we discuss recent generalizations and extensions of the HDM, to include both convection and diffusion dynamics of the induced charges. This generalized nonlocal optical response (GNOR) model allows for the first time unified semi-classical explanations of known experimental phenomena for both monomers and dimers that previously seemed to require microscopic theory. Finally, we turn to Landau damping and discuss the microscopic origin of the size-dependent damping captured by the classical diffusion mechanism in the GNOR model.
