论文摘要
在本文中，我们提出了一个由相同的各向异性谐振单元组成的连续可调节的声学跨表面，每个单元都包含一个刚性基座和可旋转的包含空间围结构的旋转包含。元表面可以通过调整包含旋转角来操纵反射阶段。理论分析表明，依赖偏振的相变可以由包含内部的均衡驻留波模式引起。通过利用可旋转的包含，我们设计了一个可调的声学地毯披肩设备，该设备可用于迅速的入射角。当入射波来自不同的方向时，可以通过排列每个包含的旋转角度获得掩蔽效果。
In this paper, we propose a continuously tunable acoustic metasurface composed of identical anisotropic resonant units, each of which contains a rigid pedestal and a rotatable inclusion with space coiling-up structure. The metasurface can manipulate the reflected phase by adjusting the rotational angle of inclusion. The theoretical analysis shows that the polarization-dependent phase change can be induced by the even-order standing wave modes inside inclusion. By utilizing the rotatable inclusion, we design a tunable acoustic carpet cloaking device, which works with a wide range for incident angle. When incident waves come from different directions, the cloaking effect can be obtained by arrange the rotational angle of each inclusion.
