GNSS Reflectometry is an emerging technique used for the remote sensing of soil surfaces. In this contribution an application of dielectric constant retrieval is presented. Both direct and reflected GPS signals were collected by a fully software receiver mounted on-board an aircraft. The reflected signal was processed with an open loop approach, obtaining(More)
In the ongoing search for new materials for microwave absorption applications, carbon nanotubes (CNTs) deserve a special consideration due to their outstanding properties. In this paper, the microwave absorbing properties of epoxy resin based composites containing three different types of commercial Multi Walled Carbon Nanotubes (MWCNTs) used as fillers(More)
In this paper, the electrical characteristics of nano-polymer composites using multiwalled carbon nanotubes (MWCNTs) with two different aspect ratios inside an epoxy resin are analyzed. The complex permittivity of the nano-composites is predicted using the Maxwell-Garnett model and McLachlan's formulation. The performed analysis showed a discrete dispersion(More)
A wide band microwave characterization of nanocomposites based on commercial multiwall carbon nanotubes (MWCNTs) and epoxy resin is presented. Field Emission Scanning Electron Microscopy is used for morphological samples analysis of nanocomposites and MWCNTs. Complex permittivity is measured using a commercial dielectric probe and a Network Analyzer. A(More)
