论文摘要
元时间表现出对波浪操纵波的前所未有的可能性。研究工作一直集中在跨境的发展上，这些元时间对一种物理性质的波动，例如电磁波。在这项工作中，我们建议使用功率流形成元素来创建多物理设备，这些设备可以同时控制不同性质的波浪。特别是，我们介绍了同时在电磁波和声波上执行指定操作的元图设备。使用基于表面阻抗的纯分析模型，我们引入了对电磁波和声波的功能相同功能的跨境，甚至更具挑战性的电磁和声学功能。我们提供了现实的拓扑来实现所提出的跨面积，并通过数值模拟确认结果。
Metasurfaces have shown unprecedented possibilities for wavefront manipulation of waves. The research efforts have been focused on the development of metasurfaces that perform a specific functionality for waves of one physical nature, for example, for electromagnetic waves. In this work, we propose the use of power-flow conformal metamirrors for creation of multiphysics devices which can simultaneously control waves of different nature. In particular, we introduce metasurface devices which perform specified operations on both electromagnetic and acoustic waves at the same time. Using a purely analytical model based on surface impedances, we introduce metasurfaces that perform the same functionality for electromagnetic and acoustic waves and, even more challenging, different functionalities for electromagnetics and acoustics. We provide realistic topologies for practical implementations of proposed metasurfaces and confirm the results with numerical simulations.
