标题： High-Capacity and Real-Time Acoustic Communication by Multiplexing Velocity

摘要： 声学通信对于水下网络、深海勘探和生物监测是不可或缺的，在这些环境中电磁波变得不切实际。 然而，与后者不同，后者矢量极化自然支持多个信息信道，声波是纵波，传统上几乎完全依赖单一标量压力信道，这对其数据承载能力构成了基本限制。 在此，我们通过理论和实验展示，声波的矢量速度可以作为类似极化的物理自由度。 使用其三个分量作为相互独立的通信信道，并通过一个矢量传感器进行解调，我们实现了可靠、高容量和实时的信息传输。 速度的复用为声学通信增加了一个新的维度。 当与其他物理自由度（频率、相位等）结合时，这种方法可以显著提高信息容量，为下一代声学技术开辟新的途径。 显示英文摘要

摘要： Acoustic communication is indispensable for underwater networks, deep ocean exploration, and biological monitoring, environments where electromagnetic waves become impractical. However, unlike the latter, whose vector polarization naturally supports multiple information channels, acoustic waves are longitudinal and have traditionally relied almost exclusively on a single scalar pressure channel, posing a fundamental limit on their data-carrying capacity. Here, we theoretically and experimentally demonstrate that the vector velocity of acoustic waves can serve as a polarization-like physical degree of freedom. Using its three components as mutually independent communication channels and demodulating them with a single vector sensor, we achieve reliable, high-capacity, and real-time information transmission. Multiplexing velocity adds a new dimension to acoustic communication. When combined with other physical degrees of freedom (frequency, phase, etc.), this approach can significantly enhance the information capacity, opening new avenues for next-generation acoustic technology.
