Abstract

Acoustic metasurfaces have shown great promise for applications in many acoustic wave modulation fields, while the use of intelligent optimization algorithms has facilitated the design of acoustic metasurfaces. In this paper, we utilize the stop band properties of phononic crystals to design a metasurface that can achieve both transmission focusing and reflection focusing, as well as a metasurface that utilizes acoustic focusing to filter the incident acoustic wave. In order to achieve the best effect, this paper uses the taboo genetic algorithm to optimize the arrangement order of the structural units controlling different focuses in the acoustic metasurface, and the optimization achieves a good focusing effect, which expands the design of acoustic metasurfaces as well as the application scenarios of acoustic focusing.

基于禁忌遗传算法的声学聚焦研究

声学元表面在许多声波调制领域都显示出巨大的应用前景，而智能优化算法的使用则促进了声学元表面的设计。在本文中，我们利用声子晶体的止带特性设计了一种既能实现透射聚焦又能实现反射聚焦的元表面，以及一种利用声聚焦过滤入射声波的元表面。为了达到最佳效果，本文利用禁忌遗传算法优化了声学元表面中控制不同聚焦的结构单元的排列顺序，优化后达到了良好的聚焦效果，拓展了声学元表面的设计以及声学聚焦的应用场景。
