Performance Analysis of Cooperative Aerial RIS for Millimeter-Wave SISO Systems

In this paper, we propose a physics-aware pathloss model for cooperative aerial reconfigurable intelligent surfaces (Co-ARIS) in millimeter-wave (mmWave) communications. The proposed model incorporates antenna radiation patterns, element-level scattering characteristics, line-of-sight (LoS) and non-line-of-sight (NLoS)...
