We present the results obtained with a custom coaxial-cage line built to measure the complex dielectric permittivity and magnetic permeability of granular and/or liquid materials. The coaxial-cage line presents an open structure to facilitate the insertion and to control the compactness of granular materials. The measurements have been performed using a Vector Network Analyzer and the electromagnetic parameters of the samples have been retrieved through the Nicolson-Ross-Weir algorithm (in case of magnetic materials) or the Boughriet algorithm (in case of non-magnetic ones). The cell has been used to characterize the electromagnetic properties of some geo-materials (clay soils and magnetite samples). The electromagnetic parameters are shown as a function of frequency (1MHz-1GHz) and temperature (about 200-298K).

Abstract
We present the results obtained with a custom coaxial-cage line built to measure the complex dielectric permittivity and magnetic permeability of granular and/or liquid materials. The coaxial-cage line presents an open structure to facilitate the insertion and to control the compactness of granular materials. The measurements have been performed using a Vector Network Analyzer and the electromagnetic parameters of the samples have been retrieved through the Nicolson-Ross-Weir algorithm (in case of magnetic materials) or the Boughriet algorithm (in case of non-magnetic ones). The cell has been used to characterize the electromagnetic properties of some geo-materials (clay soils and magnetite samples). The electromagnetic parameters are shown as a function of frequency (1MHz-1GHz) and temperature (about 200-298K).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
