利用集体变量法对具有多项式非线性的异向介质中拉曼孤子自频移的可控性进行了数学分析。多项式非线性是由于扩展的非线性极化P NL在一系列的领域E高达七阶。在广义模式下，对这些脉冲采用高斯假设。数值模拟了高斯脉冲参数下孤子参数的变化。
A mathematical analysis is conducted to illustrate the controllability of the Raman soliton self-frequency shift with polynomial nonlinearity in metamaterials by using collective variable method. The polynomial nonlinearity is due to the expanding nonlinear polarization P NL in a series over the field E up to the seventh order. Gaussian assumption is selected to these pulses on a generalized mode. The numerical simulation of soliton parameter variation is given for the Gaussian pulse parameters.
