Initial assessment of THz indoor channel with passive reflective intelligent surfaces

Abstract

Terahertz (THz) communications is expected to be an essential part of the future mobile communication system to meet the demand for ubiquitous high-speed data transmission everywhere. To overcome the limitations of THz communications, reconfigurable intelligent surface (RIS) shows their great potential. THz indoor channel measurements were performed using 1-bit and 3-bit passive-RIS fabricated as a passive reflector engraved on the PCV panel designed for a fixed angle of incidence and reflection to understand the propagation channel including RIS. A part of the initial assessments for the THz channel measurement including RIS are presented in this paper.
