摘要：
射频集成感知与通信（RF-ISAC）在地下、水下和体内等导电介质衰减电磁波达数十分贝每米的环境中效果不佳。本文提出了磁感应ISAC（MI-ISAC），一种利用MI链路固有的反应近场准静态耦合的范式，使在这些射频受限环境中实现ISAC的方法发生根本性改变。五项基础结果得以确立：（i）三轴线圈是实现可识别的联合距离和角度估计的必要且充分条件；（ii）耦合强度随着距离急剧变化，使在典型MI距离下即使在kHz级带宽下也能实现理论上的亚毫米精度；（iii）时间飞行在这样的窄带宽下无效，但耦合梯度提供了大约六个数量级更精细的分辨率；（iv）MI-ISAC在时间分隔基线基础上可提供4-10+dB的感知增益；（v）MI-MIMO信道在所有方向上均具有几何不变性和良好的条件性。讨论了应用和研究路线图。
英文摘要：
Radio-frequency integrated sensing and communication (RF-ISAC) is ineffective inunderground, underwater, and in-body environments where conductive media attenuate electromagnetic waves by tens of dB per meter. This article presents magneto-inductive ISAC (MI-ISAC), a paradigm that exploits the reactive near-field quasi-static coupling inherent to MI links, enabling a fundamentally different approach to ISAC in these RF-denied environments. Five foundational results are established: (i)~tri-axial coils are necessary and sufficient for identifiable joint range-and-angle estimation; (ii)~coupling strength changes sharply with range, enabling theoretical sub-millimeter accuracy at typical MI distances despite kHz-level bandwidth; (iii)~time-of-flight is ineffective under such narrow bandwidth, but the coupling gradient provides approximately six orders of magnitude finer resolution; (iv)~MI-ISAC can provide 4--10+\,dB sensing gain over time-division baselines; and (v)~the MI-MIMO channel is geometry-invariant and well-conditioned across all orientations. Applications and a research roadmap are discussed.
