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 statistical analysis based on one-way analysis...
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 have been analyzed. The complex permittivity...
This paper presents an optimized Waveform Relaxation solver for electrically-long high-speed channels terminated by nonlinear networks. The time-domain scattering operators of channel and terminations are cast as recursive convolutions and nonlinear discrete-time filters, respectively. A transverse and longitudinal decoupling is then applied to the channel operator, with the introduction of suitable...
