On the use of transmission line theory to represent a nonuniform vertically-extended object struck by lightning

In this study, we present an experimental validation of the transmission line representation of an elevated object struck by lightning. The experimental results are obtained using a reduced-scale model and injected signals with narrow pulse widths (down to ...

Glow discharge processing in the liquid crystal display industry

Laurent Fabien Hubert Sansonnens

The active matrix display industry is briefly presented. The most challenging aspect for plasma source design lies in the substrate size which is now entering the 1-2 m range. This paper focuses on the conventional planar RF capacitor at 13.56 MHz. A detai ...

Pressure drop and helium inlet in ITER CS1 conductor

Pierluigi Bruzzone

A number of pressure drop measurements have been carried out at CRPP on a section of ITER cable-in-conduit conductor, using pressurized water at room temperature. The longitudinal friction factor is deduced for the strand bundle area and the central hole. ...

Transient analysis of multiconductor lines above a lossy ground

Michel Ianoz

In this paper, we first extend the Sunde logarithmic approximation for the single-wire line ground impedance to the case of a multiconductor line. The new approximate forms are compared to the general expressions which involve integrals over an infinitely ...

Longitudinal spatial hole burning and associated nonlinear gain in gain-clamped semiconductor optical amplifiers

Benoît Marie Joseph Deveaud, Marc-André Dupertuis

The longitudinal spatial hole burning (LSHB) in gain-clamped semiconductor optical amplifiers (GCSOA's) is investigated by means of a numerical model, which is based on position-dependent rate equations for the carrier density and the propagation equations ...

Mapping of a stochastic magnetic field in toroidal systems

Wilfred Anthony Cooper

The topological features of a stochastic magnetic field are investigated by the tracing of magnetic field lines. The first method consists of direct integration of the field line equations. An alternative approach is to invoke the incompressibility of the ...

Sheath impedance effects in very high frequency plasma experiments

Christoph Hollenstein, Stephan Brunner, Alan Howling

The frequency dependence (13.56-70 MHz) of the ion energy distribution at the ground electrode was measured by mass spectrometry in a symmetrical capacitive impedance at very high frequency allows high levels of plasma power and substrate ion flux while ma ...

Electromagnetic field coupling to shielded cables: methodology and experimental validation

Michel Ianoz

The coupling of electromagnetic fields inside shielded cables is an important issue in EMC applications, in which the transfer impedance represents one of the main parameters. The paper discusses the last analytical expressions which have been developed fo ...

Importance of losses in the determination of lightning-induced voltages on overhead lines

Michel Ianoz

In the determination of lightning-induced voltages on overhead power lines, ground losses play a role in both the evaluation of the lightning radiated electromagnetic fields and of the line parameters. The aim of this paper is to assess the effect of these ...

On the contribution of the electromagnetic field components in field-to-transmission line interaction

Carlo Alberto Nucci

Based on the transmission line approximation, three different equivalent formulations have been proposed for evaluating the interaction between an external electromagnetic field and a transmission line. The difference among these 'coupling' formulations, w ...
