A new framework to estimate the formation factor of granular materials using high frequency electromagnetic measurements

This dataset supports the study "A new framework to estimate the formation factor of granular materials using high frequency electromagnetic measurements". Measurements with VNA Keysight E5061B, SOLT Calibration, 1 MHz - 3 GHzCoaxial Cell, Flow Through sample holder 5 Granular Materials:GlassBeads (Mono disperse)GlassBeadsMixtureFineCrushedGlassSigmaSandNaturalSand For each material, measurement of effective relative complex permittivity and effective conductivity are performed with different saturating liquids:- with brines- with fluids (air, deionized water and 1 solvent at least) Available Data:- Meas: structure containing all the measurements. For each material a sub section is available with measured scattering function Sij and computed electrical properties from iterative method.- Optim: structure containing all the fitted spectrums. For each material a sub section is available with the computed electrical properties from optimization method.
