Abstract:
This paper presents comprehensive double-directional channel measurements at 300 GHz across various corridor scenarios, including Access, Device-to-Device (D2D), and Backhaul, using an in-house developed channel sounder. The measurements, validated by ray tracing simulations, reveal that while 300 GHz quasi-optical propagation in corridors can be modeled using ray optics, non-trivial propagation phenomena, such as quadruple-bounce reflections, also occur. To accurately model these mechanisms, a quasi-deterministic (QD) channel model combining deterministic and random components is proposed. The QD model results align well with observations, highlighting similar propagation mechanisms for Access and D2D scenarios, while Backhaul scenarios show Line-of-Sight (LoS) impacts from ceiling reflections. These findings are crucial for designing next-generation THz communication systems.
