论文摘要
在这封信中，我们研究了基于旋转正方形机制沿柔性超材料的自由表面的非线性脉冲的传播。尽管这些分类物以前已被证明可以通过其大量支持弹性载体孤子的传播，但在这里我们证明它们也可以支持沿自由表面的非线性脉冲的稳定传播。此外，我们表明，当这些表面脉冲与线性色散表面模式相互作用时，它们的稳定性更高。最后，我们提供指南来选择最小化此类相互作用的几何形状。
In this letter we investigate the propagation of nonlinear pulses along the free surface of flexible metamaterials based on the rotating squares mechanism. While these metamaterials have previously been shown to support the propagation of elastic vector solitons through their bulk, here we demonstrate that they can also support the stable propagation of nonlinear pulses along their free surface. Further, we show that the stability of these surface pulses is higher when they minimally interact with the linear dispersive surface modes. Finally, we provide guidelines to select geometries that minimize such interactions.
