In the evolving landscape of terahertz communication, the behavior of channels within indoor environments, particularly through glass doors, has garnered significant attention. This paper comprehensively investigates terahertz channel performance under such conditions, employing a measurement setup operational between 113 and 170 GHz. Analyzing scenarios frequently induced by human activity and environmental factors, like door movements, we established a comprehensive theoretical model. This model seamlessly integrates transmission, reflection, absorption, and diffraction mechanisms, leveraging the Fresnel formula, multi-layer transmission paradigm, and knife-edge diffraction theory. Our experimental results and theoretical predictions harmoniously align, revealing intricate dependencies, such as increased power loss at higher frequencies and larger incident angles. Furthermore, door interactions, whether opening or oscillations, significantly impact the terahertz channel. Notably, door edges lead to a power blockage surpassing the transmission loss of the glass itself but remaining inferior to metallic handle interferences. This paper's insights are pivotal for the design and fabrication of terahertz communication systems within indoor settings, pushing the boundaries of efficient and reliable communication.

透过玻璃门的太赫兹通道性能的实验和理论探索

在不断发展的太赫兹通信领域，室内环境中的通道行为，特别是通过玻璃门的通道行为，引起了人们的广泛关注。本文采用在 113 至 170 GHz 之间运行的测量装置，全面研究了此类条件下的太赫兹通道性能。通过分析人类活动和环境因素（例如门的移动）经常引发的场景，我们建立了一个全面的理论模型。该模型利用菲涅尔公式、多层传输范式和刀口衍射理论，无缝集成了透射、反射、吸收和衍射机制。我们的实验结果和理论预测和谐一致，揭示了复杂的依赖性，例如较高频率和较大入射角时功率损耗增加。此外，门的相互作用，无论是打开还是振荡，都会显着影响太赫兹通道。值得注意的是，门边缘导致的电力阻塞超过了玻璃本身的传输损耗，但仍低于金属把手的干扰。本文的见解对于室内环境中太赫兹通信系统的设计和制造至关重要，突破了高效可靠通信的界限。
