AI 中文摘要
磁耦合通信（MIC）是一种颇具前景的地（TTE）下通信技术。过往针对MIC通信范围的研究往往忽略了地下材料引发的涡流损耗影响。对于TTE MIC而言，显著的涡流损耗使有效MIC通信范围的分析变得复杂，而这一范围对优化性能至关重要，却从未在相关文献中得到解决。本文考虑地下介质的电导率和介电常数，推导了TTE MIC的有效MIC通信范围，同时得出了可预测最优载波频率的闭式表达式，该频率用于最大化此范围。有限元仿真验证了该分析，表明最优载波频率可显著提升MIC通信范围。研究还发现，优化天线半径对于扩展TTE和车载MIC应用的MIC通信范围是有效的。
英文摘要
Magnetic induction communication (MIC) is a promising technology for through-the-earth (TTE) communication. Previous studies on the MIC range have often overlooked the impact of eddy losses caused by underground materials. For TTE MIC, significant eddy losses complicate the analysis of the effective MIC range, which is vital for optimizing performance but has never been addressed in the literature. Accounting for the conductivity and permittivity of the underground medium, this paper derives the effective MIC range in TTE MIC, along with a closed-from expression that predicts the optimal carrier frequency to maximize this range. Finite element simulations validate the analysis, demonstrating that the optimal carrier frequency can significantly enhance the MIC range. It is also revealed that optimizing the antenna radius is effective in extending the MIC range for TTE and vehicle MIC applications.
