摘要
近年来,声学超材料作为一种新型人工复合材料,凭借其强大的声学参数调控能力突破传统材料功能极限,在水下探测、目标识别、成像、导航和通信等领域展现出了广阔的应用前景.文章综述了利用超材料实现水声通信的研究进展,主要包括基于声轨道角动量的多路复用通信、基于声学超表面的波束操控实现的特定发射和接收端间的水声通信,以及水-空跨介质声通信,总结了其所涉及的关键技术,并对当前基于超材料的水声通信所面临的挑战和前景进行了展望.
Abstract
In recent years,acoustic metamaterials,as a sort of novel artificial composite materials,have demonstrated the ability to surpass the limitations of traditional materials through their exceptional acoustic parameter manipulation capabilities.Thus,acoustic metamaterials have shown promising applications in numerous areas such as underwater detection,underwater target identification,acoustic imaging,navigation,and underwater communication.The advancements in metamaterial-based underwater acoustic communication were reviewed,focusing primarily on multiplex communication based on acoustic orbital angular momentum,underwater acoustic communication between specific transmitter and receiver based on beam steering of acoustic metasurface,and water-air trans-medium acoustic communication.The key technologies were summarized,and the current challenges and future prospects of metamaterial-based underwater acoustic communication were outlined.
