Experimental Study of Diffuse Scattering from Typical Construction Materials over 40-50GHz

This paper presents a measurement campaign of diffuse scattering pattern from six typical construction materials, including granite, marble, plasterboard, wooden board, rough stone and ceramic tile over a frequency range from 40 GHz to 50 GHz using relatively simple measurement setup. Analysis of the experimental results indicates that diffuse scattering is concentrated around specular reflection direction and has a much greater impact on received power at slant incidence mode than normal incidence mode at 45 GHz. The measured results can be applied in ray-tracing tool to predict mm-Wave propagation for future wireless communication.
