Nanoporous gold and platinum electrodes are used to pattern n-type silicon by contact etching at the macroscopic scale. This type of electrode has the advantage of forming nanocontacts between silicon, the metal and the electrolyte as in classical metal assisted chemical etching while ensuring…

Six-port technology for millimeter-wave metrology

Kamel Haddadi, Christophe Loyez, Katir Ziouche

The six-port measurement technique has played a major role in vector network analysis metrology, particularly within the community of national standards laboratories. Thanks to reduced hardware resource in contrast with conventional and well-established down-mixing heterodyne technique, this paper…

Performance assessment of a small-size ocean wave energy harvester

Yongjie Sang, Bertrand Dubus

A lightweight electromechanical device is studied to harvest energy of ocean waves and supply electrical power to small-size ocean observation equipment such as sonobuoys. It is composed of a magnet fixed to the floating housing which follows the motion of the ocean surface and a moving coil…

On the impact of the covariance matrix size for spectrum sensing methods:beamforming versus eigenvalues

Kais Bouallegue, Matthieu Crussière, Iyad Dayoub

In this paper, we investigate the impact of the covariance matrix (CM) size of the received signal on the performance of spectrum sensing methods. Our analysis is based on two well-known methods of spectrum sensing (SS), one based on the eigenvalues called maximum-to minimum eigenvalue (MME) and…

A method to determine wide bandgap power devices packaging interconnections

Loris Pace, N. Defrance, Jean-Claude de Jaeger, Arnaud Videt, Nadir Idir

Wide Bandgap (WBG) power devices show very good characteristics for high frequency operation in power converters, leading to a better power integration by reducing size and weight of passive components. Access parasitics such as resistances and inductances related to packaging and interconnections…
