title = "Building Material Permittivity and Conductivity Estimation from 2 to 260 GHz",
abstract = "This paper analyzes the frequency-dependent electromagnetic characteristics of usual flat-surface low-loss building materials. Reflection and transmission losses are measured from 2 to 260 GHz and the related permittivity and conductivity are estimated. Results are in agreement with the ITU-R P2040-3 model that is mainly defined for frequency below 100 GHz. The permittivity can be modelled by a constant value and the conductivity can be modelled by a frequency-dependent function equal to afb. Some differences between the measured and simulated transmission losses have been observed for composite materials that can no longer be considered as homogeneous for frequency above 50 GHz.",
