本文针对毫米波室内覆盖问题，首次实验表征沿墙壁的毫米波侧向波，建立其路径损耗模型，为新型界面引导毫米波链路提供经验基础。
AI 中文摘要
高频毫米波（mmWave）通信系统受周围环境限制，室内场景中墙壁传统上被视为阻挡或反射信号的障碍物，因此当前的波束成形策略都旨在规避这些障碍物。本文提出了一种范式转变，即利用沿建筑界面传播的侧向波来扩展毫米波覆盖范围。与传统反射不同，侧向波在两种不同折射率介质的边界传播，且随距离呈代数衰减，为毫米波连接提供了潜在的替代路径。尽管侧向波在自然介质的低频下已得到充分证实，但工程建筑材料上的毫米波频段侧向波的存在此前尚未得到验证。为此，本文报告了沿墙壁的毫米波侧向波的首次实验表征，采用大量受控测量来表征信号掠射几何，并建立了该现象的频率和距离相关路径损耗模型。研究结果为新型界面引导毫米波链路提供了首个经验基础。
英文摘要
High-frequency millimeter-wave (mmWave) communication systems are constrained by the surrounding environment, where walls are traditionally treated as obstacles that block or reflect signals indoors. Consequently, current beamforming strategies are tailored to circumvent these obstructions. In this paper, a paradigm shift is introduced that leverages lateral wave propagation along building interfaces to extend mmWave coverage. Unlike traditional reflections, lateral waves travel along the boundary between two media of different refractive indices and decay algebraically with distance, offering a potential alternative path for mmWave connectivity. While well-established at low frequencies in natural media, the existence of lateral waves at mmWave frequencies along engineered building materials has not been demonstrated before. To this end, the first experimental characterization of mmWave lateral waves along a wall is reported. Extensive controlled measurements are employed to characterize the signal-grazing geometry and to establish a frequency and distance-dependent path-loss model for this phenomenon. The results provide the first empirical foundation for a new class of interface-guided mmWave links.
