提出了一个动态模型，具有强烈变化的介质中的高频非线性固体传播。 ，重点介绍了与宏观非线性量子振荡器模型的类比分析结果通过数值模拟证实。
High‐frequency nonlinear solitary wave propagation in media with strongly varying dispersion is considered. A dynamical model is proposed which allows us to determine the propagation characteristics of a strongly dispersion‐managed soliton without applying any averaging procedure. This approach is compared with previously developed models, focusing on the dependence of the energy on the quasimomentum. An analogy with a macroscopic nonlinear quantum oscillator model is briefly discussed. The analytical results are confirmed by numerical simulations.
