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 ...

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 ...

Broadband Fabry-Pérot radiation based on a non-Foster cavity boundary

Julien Perruisseau-Carrier, Tomislav Debogovic

Fabry-Perot (FP) cavities having at least one partially reflective surface are widely used as compact and efficient high-directivity radiators. However, they inherently suffer from very narrow directivity bandwidths around the FP resonance. Here it is show ...

Numerical modelling of electromagnetic turbulent transport of energetic ions in burning plasmas

Ambrogio Fasoli, Jonathan Graves, Wilfred Anthony Cooper, Martin Jucker, Mattia Albergante

We investigate the redistribution of the neutral beam driven current in the presence of small scale turbulence in the ITER steady-state scenario. Gyrokinetic simulations show that anomalous transport of beam ions can be larger than collisional estimates. T ...
