Propagation Measurements and Coverage Analysis for mmWave and Sub-THz Frequency Bands with Transparent Reflectors
2023 IEEE 97TH VEHICULAR TECHNOLOGY CONFERENCE, VTC2023-SPRING.
author keywords: 5G; 6G; channel sounding; curved reflectors; flat reflectors; mmWave; ray tracing; sub-THz; transparent reflectors
TL;DR:
Analysis of the use of passive transparent reflectors to improve signal coverage in an NLOS indoor scenario reveals that the transparent reflector outperforms the metal reflector and increases the radio propagation coverage in all three frequencies of interest: 28 GHz, 39 GHz, and 120 GHz.

Coverage Enhancement for NLOS mmWave Links Using Passive Reflectors
IEEE OPEN JOURNAL OF THE COMMUNICATIONS SOCIETY, 1, 263–281.
author keywords: Coverage; indoor; mmWave; non-line-of-sight (NLOS); outdoor; PXI; ray tracing (RT); reflector
TL;DR:
This work provides an analytical model for the end-to-end received power in an NLOS scenario using reflectors of different shapes and sizes and shows that the reflected received power for the NLOS link is the same as line-of-sight (LOS) free space received power of the same link distance.
