跨介质磁感应通信研究进展:理论、技术与应用OA

To address physical challenges including wave impedance mismatch at media interfaces and severe signal at-tenuation in high-loss media,magnetic induction communication was adopted,owing to the continuous transboundary propagation capability and inherent low-loss characteristics of quasi-static magnetic fields.Firstly,fundamental cross-medium propagation theories,non-trivial lateral wave phenomena,and eddy current losses in dielectric media were com-prehensively considered.Secondly,recent research advancements in this field were systematically reviewed across four core dimensions:transceiver hardware design,physical-layer transmission and modulation schemes,channel modeling,and relay-assisted networking technologies.Meanwhile,magnetic induction communication was applied to typical applica-tion scenarios,including ocean monitoring and underground rescue operations.On this basis,the existing bottlenecks in both physical mechanism research and engineering implementation were discussed in depth,and key promising technolo-gies,including dynamic channel modeling,novel transceiver hardware,and quantum sensing,were further identified.These insights provide a valuable and practical reference for realizing seamless connectivity in heterogeneous cross-medium environments.
