本文介绍了Monolith，一个高比特率，低功耗，超材料表面的轨道角动量（OAM）MIMO复用设计秩不足，自由空间无线环境。利用环境信号作为电源，Monolith通过将这些环境信号调制成几个正交光束来反向散射这些环境信号，其中每个光束都携带唯一的OAM。我们提供见解沿着设计方面的低功耗和可编程的超材料为基础的表面。我们的研究结果表明，Monolith实现了一个数量级更高的信道容量比传统的空间MIMO后向散射网络。
This paper presents Monolith, a high bitrate, low-power, metamaterials surface-based Orbital Angular Momentum (OAM) MIMO multiplexing design for rank deficient, free space wireless environments. Leveraging ambient signals as the source of power, Monolith backscatters these ambient signals by modulating them into several orthogonal beams, where each beam carries a unique OAM. We provide insights along the design aspects of a low-power and programmable metamaterials-based surface. Our results show that Monolith achieves an order of magnitude higher channel capacity than traditional spatial MIMO backscattering networks.
