Intermittency and blob dynamics in the TORPEX device

Intermittent convective transport caused by blobs is universally observed at the edge of laboratory plasmas and it is of great importance for future fusion reactors. We present recent advances in the basic study of blob formation and propagation dynamics a ...

Blob motion and control in simple magnetized plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Benoît Labit, Christian Gabriel Theiler, Nicola Vianello, Davoud Iraji

Intermittent convective transport caused by coherent structures, or blobs, are universally observed in the edge of laboratory plasmas. Besides being of fundamental physics interest, the dynamics of these structures in fusion reactors influence the density ...

Making a Reconfigurable Artificial Crystal by Ordering Bistable Magnetic Nanowires

Dirk Grundler

Spin-wave excitations (magnons) are investigated in a one-dimensional (1D) magnonic crystal fabricated out of Ni80Fe20 nanowires. We find two different magnon band structures depending on the magnetic ordering of neighboring wires, i.e., parallel and antip ...

Superconducting parallel nanowire detector with photon number resolving functionality

Francesco Marsili, Alessandro Gaggero

We present a new photon number resolving detector (PNR), the Parallel Nanowire Detector (PND), which uses spatial multiplexing on a subwavelength scale to provide a single electrical output proportional to the photon number. The basic structure of the PND ...

Investigation of bias-dependent series resistances and barrier height in Double Gate Schottky MOSFETs

Mihai Adrian Ionescu, Jean-Michel Sallese, Jyotshna Bhandari

This work reports on gate voltage dependent source and drain series resistance and associated barrier height in modified Double Gate Schottky MOSFETs with dopant segregation. We show that in our devices the series resistances is significantly reduced by lo ...

Shunt loudspeaker techniques for use as liners for engine nacelles

Hervé Lissek

In this paper, the liner concept is an electroacoustic transducer which acoustic impedance can be changed by electrical means, be it passive or active. Among the different ways to obtain variable acoustic properties on an electroacoustic transducer's voici ...

Physics and application of photon number resolving detectors based on superconducting parallel nanowires

Francesco Marsili, Alessandro Gaggero

The parallel nanowire detector (PND) is a photon number resolving (PNR) detector that uses spatial multiplexing on a subwavelength scale to provide a single electrical output proportional to the photon number. The basic structure of the PND is the parallel ...

Design of switching amplifier used in negative impedance dispoal for the active control of transducer's acoustic impedance

Hervé Lissek, Romain Boulandet, Pavel Mokry

We present a concept of "active material" with variable acoustic properties, being constituted of an electroacoustic transducer which acoustic impedance can be changed by an active mean. Among the different ways to obtain variable acoustic properties on an ...

Efficiency enhancement and frequency-tunable capability in linear CMOS RF power amplifiers for wireless applications

Paulo Augusto Dal Fabbro

This research work deals with the design of linear CMOS RF power amplifiers. Two important aspects are treated: efficiency enhancement and frequency-tunable capability. For this purpose, two different integrated circuits were realized in a 0.11 µm technolo ...
