Abstract
⺠Parametric dielectric properties of cometary analog materials are measured. ⺠We establish the dielectric constant dependence on porosity, dust fraction and temperature. ⺠We build two 3D dielectric models of Comet 67P to support future nucleus tomography. ⺠Different hypotheses on 67P's inner properties can be inferred from the dielectric properties. ⺠Surface temperature variation can induce measurable variations in the comet radar properties.
