Ray Tracing Based RIS-Assisted Corridor Environment Channel Reconstruction at 300GHz

Reconfigurable intelligent surfaces (RIS) have emerged as a crucial technology for sixth-generation (6G) communication systems. Mastering the modeling and analysis methods of RIS is essential for its effective implementation. In this paper, a channel reconstruction model is proposed based on ray tracing (RT) simulations in an indoor corridor environment at 300 GHz. It can reconstruct the extracted multipath components (MPCs) to enhance their accuracy and alignment with real-world measurement environments. By analyzing the power delay profile (PDP), power angular profile (PAP), and path loss (PL) before and after integrating RIS, the accuracy and effectiveness of the proposed method are verified. It has also confirmed that RIS significantly improves the transmission efficiency and extends the signal coverage of communication systems.
