摘要

太赫兹信道反射特性对于认知、掌握太赫兹信道传播机理，以及建立面向6G的高精度太赫兹信道模型至关重要。为此，首先，综述了太赫兹信道反射特性在理论建模和实测分析两方面的研究现状。接着，针对5种常见建筑材料，利用基于时域相关原理的太赫兹信道测量平台开展了240～310 GHz频率范围的反射系数测量，并发现了反射系数依赖于电磁波的入射角。然后，参考Rayleigh反射系数理论模型，提出了入射角依赖的反射系数统计性模型，该模型能准确刻画反射系数随角度的变化规律。最后，展望了太赫兹信道反射特性的研究方向。

Abstract

The reflection characteristics of the terahertz channel are crucial for understanding and mastering the propagation mechanism of the terahertz channel

which are also required for a high-precision terahertz channel model for 6G.Therefore

the research status of terahertz channel reflection characteristics in theoretical modeling and measurement analysis were first summarized.Then

the reflection coefficient measurement campaign in the frequency range of 240 GHz to 310 GHz for five kinds of common building materials was conducted by a time-domain correlation-based terahertz channel measurement platform.It was found that the reflection coefficients were related to the incident angle.Based on the Rayleigh reflection coefficient theoretical model

a statistical reflection coefficient model was further proposed as a function of incident angle.Generally

the proposed model could accurately describe the variation law of the reflection coefficient with angle.Finally

research directions of terahertz channel reflection characteristics were discussed.
