Deployment of a UAV-Mounted Intelligent Reflecting Surface in the THz Band

Abstract

The design of RIS-assisted THz wireless systems is envisioned to be one of the key roles in 6G evolution. In this paper, we implement an analytical pathloss model for reconfigurable intelligent surface (RIS) in terahertz (THz) band. We study the optimal 3D deployment problem and configuration of UAV-Mounted RIS in THz band environment with the objective of maximizing the achievable rate of the network considering the distances from transmitter/receiver to the RIS, blockage probability, the far field constraints for unit cells and antennas, the size of the RIS, absorption loss and we provide a discussion that can serve as guidelines for researchers and mobile network operators for designing UAV-Mounted RIS in the THz Band.
