Helicon wave-generated plasmas for negative ion beams for fusion

Ivo Furno, Alan Howling, Gennady Plyushchev, Riccardo Agnello, Philippe Frédérique Bruno Guittienne, Rémy Jacquier, Claudio Marini

In the next generation of fusion reactors, such as DEMO, neutral beam injectors (NBIs) of high energy (0.8-1 MeV) deuterium atom swith high wall-plug efficiency (>50%) will be required to reach burning plasma conditions and to provide a significant amount ...

A Switched Oscillator Geometry Inspired by a Curvilinear Space-Part II: Electrodynamic Considerations

Farhad Rachidi-Haeri

This is the second part of a two-part paper in which we present a new technique for the design of coaxial switched oscillators (SWOs). In this part, we present a model for the analysis of the signal radiated by the SWO, in both frequency and time domains. ...

A Methodology to Reduce the Computational Effort in the Evaluation of the Lightning Performance of Distribution Networks

Farhad Rachidi-Haeri

The estimation of the lightning performance of a power distribution network is of great importance to design its protection system against lightning. An accurate evaluation of the number of lightning events that can create dangerous overvoltages requires a ...

Diminishing SAR for Wearable UHF Antennas

Anja Skrivervik, Jovanche Trajkovikj

This letter presents a study on the specific absorption rate (SAR) evaluation of UHF wearable antennas. A planar inverted-F antenna (PIFA) intended to operate in wireless body area networks (WBANs) is taken as an example for the investigation. The presence ...

Feeding structure influence on performance of two UWB antennas near a human arm

Anja Skrivervik, Mohsen Koohestani

This paper reports a study of the feeding structure influence on impedance matching and system fidelity factor of two loaded UWB antennas when placed near a human arm. To this aim, two identical dielectric loaded versions of the same UWB antenna designs wi ...

On the selection of radiating elements for compact indoor massive-multiple input multiple output base stations

Julien Perruisseau-Carrier

Massive-multiple input multiple output (MIMO) was recently proposed as a key solution for improving the performance of multi-user MIMO in future cellular generations. The main paradigm in this novel MIMO technique is to use a very large number of antenna e ...

Small antennas as wireless system components

Nuno Miguel Faria Pires

Small antennas, or more specifically, electrically small antennas, are passive radiating elements whose size is much smaller than the operating wavelength. The current wireless application systems usually have size constraints that, for the most common ope ...

Resonant RF network antennas for large-area and large-volume inductively coupled plasma sources

Christoph Hollenstein, Alan Howling, Philippe Frédérique Bruno Guittienne

Large-area and large-volume radio frequency (RF) plasmas are produced by different arrangements of an elementary electrical mesh consisting of two conductors interconnected by a capacitor at each end. The obtained cylindrical and planar RF networks are res ...
