Nondispersive acoustic manipulation based on gradient curved waveguides
- 发表刊物：Journal of Applied Physics
- 摘要：We propose that the propagation of acoustic waves in two-dimensional space can be controlled by the design of gradient embedded paths, which is inspired by a combination of metasurfaces and the inverse method of transformation optics. The phase variation along each gradient embedded path is smooth so that there is almost no reflection below a critical frequency. More importantly, the functionalities of devices designed by our approach are frequency-independent over a pretty broad band. In our work, gradient embedded paths are realized with gradient curved waveguides. Various potential …
