短程透镜中的弹性波操纵
Elastic wave manipulation in geodesic lenses
摘要：
我们研究波在弯曲的薄弹性波导中的传播，其中曲率被证明是等同于空间调制的折射率。我们建立这种关系的理论框架内，利用非欧几里德变换。理论预测说明了如何弯曲的配置文件可以设计操纵波的轨迹与几何光学原理类似。3D打印弯曲膜的实验证实了理论预测，并建议曲率作为引导，聚焦和操纵弹性波的可行方法。
英文摘要：
We investigate wave propagation in curved, thin elastic waveguides, where curvature is shown to be equivalent to a spatially modulated refractive index. We establish this relationship within a theoretical framework that leverages non-Euclidean transformations. Theoretical predictions illustrate how curved profiles can be designed to manipulate wave trajectories in analogy with geometrical optics principles. Experiments on 3D printed curved membranes confirm the theoretical predictions, and suggest curvature as a viable approach for guiding, focusing and steering of elastic waves.
