Experimental Reflection Characteristics of 253 GHz in a Small Closed-room

This paper presents the experimental reflection characteristics based on measurements in a small closed-room at 253 GHz. The reflection coefficients of interior construction materials such as concrete, wood, and metal are firstly investigated. As a result of measuring the power distribution of multipath signals reflected in a small closed-room and comparing them with the ray-tracing simulation results, we observed that multipath signals reflected more than once were distributed in various angles.
