Deterministic Ray Tracing: A Promising Approach to THz Channel Modeling in 6G Deployment Scenarios IEEE Commun. Mag. (IF 11.2) Pub Date : 2024-02-19 Jianhua Zhang, Jiaxin Lin, Pan Tang, Wei Fan, Zhiqiang Yuan, Ximan Liu, Huixin Xu, Yejian Lyu, Lei Tian, Ping Zhang
Terahertz (THz) communication is considered to be a key enabling technology for 6G due to its abundant available spectrum resources. One pre-requisite for implementing THz communication systems is to understand and model the THz radio channel in 6G deployment scenarios. However, new radio characteristics in THz bands (e.g., channel sparsity, near-field propagation, and large-scale antenna configuration)
