The Surface Reflectivity of Common Construction Materials Measured in the W-Band (75-110 GHz)

Abstract

This document describes the measurement of the relative complex permittivity for common construction materials in the W-band (75-110 GHz). These measurements are performed in free-space with a network analyzer. The results are compiled into a set of permittivities at 95 GHz and translated into reflectivity coefficients as a function of incident angle. The materials measured include acrylic, gypsum drywall, plywood, cement and clay bricks, glass, sand, concrete, and asphalt.
