摘要

太赫兹信道传播特性对太赫兹通信系统的设计、评估和优化至关重要。此外，反射在信道传播中起着重要作用。本文基于大量的信道测量工作，对太赫兹通道的反射系数进行研究。首先，建立从220 GHz到320 GHz的太赫兹信道测深平台，入射角范围从10°到80°。根据实测的传播损耗，分别计算玻璃、瓷砖、木板、石膏板和铝合金五种建筑材料的频率和入射角的反射系数。研究发现，由于缺乏与太赫兹相关的参数，导致非金属材料的菲涅耳模型无法成功地拟合实测数据。因此，通过改进菲涅耳模型与洛伦兹和德鲁德模型，提出一个频角二维反射系数模型。该模型表征了反射系数的频率和入射角，与实测数据的均方根误差较小。总的来说，这些结果对于太赫兹通道的建模做出贡献。
