论文摘要
无线通信系统中包含物质识别是一个新兴领域，为6G系统提供了许多机会。通过使用反射的无线电波来确定反射表面的材料，不仅可以改善6G网络的性能，而且还可以开发一些令人兴奋的应用程序。在本文中，我们回顾了一些先前的材料识别方法，然后分析反射表面对反射系数的厚度的影响，并提出了一个新的概念“沉降厚度”，这表明反射表面的最小厚度以诱导稳定的反射系数。最后，我们提出了一种基于射线追踪和3D图的新型材料识别方法。与仅在单弹性反射方案中实现的一些先前方法相比，我们将方法的能力扩展到多重反射方案。
The inclusion of material identification in wireless communication system is an emerging area that offers many opportunities for 6G systems. By using reflected radio wave to determine the material of reflecting surface, not only the performance of 6G networks can be improved, but also some exciting applications can be developed. In this paper, we recap a few prior methods for material identification, then analyze the impact of thickness of reflecting surface on reflection coefficient and present a new concept "settling thickness", which indicates the minimum thickness of reflecting surface to induce steady reflection coefficient. Finally, we propose a novel material identification method based on ray-tracing and 3D-map. Compared to some prior methods that can be implemented in single-bounce-reflection scenario only, we extend the capability of the method to multiple-bounce-reflection scenarios.
