Abstract

Reflective metasurfaces have emerged as a crucial component for 6G communications due to their capacity for effective signal control and modulation in the high-frequency range. A simple and accurate path loss model for metasurfaces is fundamental for optimizing metasurface-assisted wireless communication systems. This study proposes an anomalous reflective metasurface structure based on a Metal-Insulator-Metal (MIM) configuration. Using a real-time high-frequency measurement system, the path loss of this metasurface-assisted wireless communication system was measured across three dimensions: broad bandwidth (230 GHz to 330 GHz), wide incidence angle (0°to 40°), and reception distance (0.5 m to 1.9 m). Experimental results were compared with the predictions of the metasurface-assisted path loss model, confirming its accuracy and applicability at frequencies from 230 GHz to 330 GHz. Moreover, we outline the conditions for model applicability and the design parameter requirements for metasurface unit structures in the aforementioned frequency range. These measurement data facilitate the development of accurate channel models, offering valuable support for the design and optimization of communication systems, thereby enhancing their performance and reliability.

基于mimm的230-330 GHz异常反射超表面辅助无线信道路径损耗测量

反射超表面由于其在高频范围内有效控制和调制信号的能力，已成为6G通信的关键组件。一个简单准确的超表面路径损耗模型是优化超表面辅助无线通信系统的基础。本研究提出了一种基于金属-绝缘体-金属（MIM）结构的异常反射超表面结构。利用实时高频测量系统，该超表面辅助无线通信系统的路径损耗在三个维度上进行了测量：宽带（230 GHz至330 GHz）、宽入射角（0°至40°）和接收距离（0.5 m至1.9 m）。实验结果与超表面辅助路径损耗模型的预测结果进行了比较，验证了超表面辅助路径损耗模型在230 ~ 330 GHz频率范围内的准确性和适用性。此外，我们还概述了上述频率范围内超表面单元结构的模型适用性条件和设计参数要求。这些测量数据有助于建立准确的信道模型，为通信系统的设计和优化提供有价值的支持，从而提高通信系统的性能和可靠性。
