Abstract

The excitation and propagation of plasmon–polariton modes are considered at a single interface of a dielectric medium and metal in linear and nonlinear regimes. Physical mechanisms of the emergence of a nonlinear response of free electrons in the metal based on the quantum hydrodynamic model are described. It is shown that the period and profile of the envelope of a cnoidal wave of surface plasmon–polaritons in the nonlinear regime change, depending on the conditions of excitation and the energy density of the exciting electromagnetic wave.

表面等离振子-Polaritons流中的线性和非线性现象

摘要

在线性和非线性状态下,在电介质和金属的单个界面处考虑了等离振子-极化子模式的激发和传播。描述了基于量子流体动力学模型的金属中自由电子非线性响应出现的物理机制。结果表明,在非线性状态下,表面等离激元-极化子的正弦波的包络的周期和轮廓根据激励的条件和激励的电磁波的能量密度而变化。
