The equivalent single-conductor model of a multiwall carbon nanotube (MWCNT) interconnect is derived analytically from the rigorous formulation of the complex multiconductor transmission-line propagation equations. The expressions of the per-unit-length (p.u.l.) equivalent quantum capacitance and kinetic inductance are obtained in closed form. A new(More)
The purpose of this paper is to investigate the use of equivalent-layer models for the analysis of carbon-fiber composite materials. In this paper, we present three different models for the electromagnetic characterization (effective material properties) of fiber composites that are commonly used in aircraft and EMC/EMI shielding materials. These three(More)
Induced-Voltage Waveform Influenced By a Branch: The waveform of the induced voltage on a 500m-long trunk line is considerably affected by the presence of a branch Although the aspect of the influence of a branch is complex, the cause of its influence can be broken down to the magnitude and the delay of the induced traveling wave on the branch, and the(More)
In this paper, hybrid transmission line-quantum mechanical models are proposed for the analysis of the signal propagation along metallic and quasi-metallic single-wall carbon nanotube (SWCNT) and bundles of SWCNTs. The analysis is based on the general assumption that the SWCNT is characterized by <i>n</i> energy subbands crossing the Fermi level. The(More)
The interaction of lightning with an aircraft induces voltages and currents in the onboard wire harnesses, which can cause critical electronic equipment damage or malfunction, thus compromising the flight safety. The lightning interaction with an aircraft made largely of composite materials, like Boeing 787 and Airbus 380, is a subject of strong interest to(More)
A procedure is proposed to test the bit-transport capability of the multi-carrier scheme on distribution power networks in the frequency range of 1-30 MHz. A frequency-dependent rigorous model of medium-voltage power networks made of branches of three-phase lines above a dissipative ground is utilized. The radiated electromagnetic field is predicted by(More)
Graphite nanoplatelets (GNPs) are bidimensional carbon nanostructures consisting of stacks of graphene sheets, having thickness in the range from one up to a few tens of nanometers, and lateral linear dimension in the micrometer range. These nanostructures represent a good candidate to replace carbon nanotubes in composites for electromagnetic applications.(More)
This paper presents the design and the realization process for radar absorbing panels made of composite materials. It is demonstrated that the proper selection of the carbon fiber length and volume fraction allows reducing sensibly the overall thickness of the screen compared to a standard absorber, and obtaining at the same time broad-band absorption(More)
This paper presents an innovative test procedure for the prediction of the shielding effectiveness of small sample materials, consisting of a dielectric substrate coated with thin conducting film, in a wide frequency range up to 8 GHz. The proposed technique overcomes the limitations of the ASTM D4935 test method concerning the upper operating frequency and(More)
A robust design of the propagation characteristics of interconnect structures based on multiwall carbon nanotubes (MWCNTs) is carried out. The study allows us to identify the minimum number of shells N of the MWCNT able to guarantee that the time delay at 50% outperforms the Cu-based solution for the upcoming technology nodes, taking into account the(More)
