利用拟粒子方法，研究了线性和非线性性质稍有不同的两种χ(2)介质界面上二次空间孤子的反射问题。给出了与非线性表面波激发有关的界面捕获孤子的可能性。本文对已知的单峰孤子和一种新型的多峰孤子进行了计算，首次在非局部极限下得到了新的解析表达式。
Using the quasi-particle approach, we studied the problem of the reflection of quadratic spatial solitons from an interface between two χ(2) media with slightly different linear and nonlinear properties. The possibility of soliton capture by an interface associated with nonlinear surface wave excitation is shown. The calculations are carried out for the well-known single as well as a novel type of multihump soliton, for which we obtain a new analytical expression in the nonlocal limit for the first time to our knowledge.
