In this paper, a coaxial cell with an integrated flow through is presented. This new apparatus is meant to investigate the broadband dielectric properties of granular material under controlled hydraulic, chemical and biological boundaries. The cell was calibrated by using a measurement on deionized water. The main idea is to optimize a forward TEM model based on a five section coaxial transmission line and assuming a Debye model for the complex relative permittivity of deionised water. The results of the calibration are presented.
