Tunable millimeter-wave phase shifter based on dielectric elastomer actuation

Herbert Shea, Julien Perruisseau-Carrier, Samuel Rosset, Pietro Romano

A very low-loss tunable millimeter-wave phase shifter driven by dielectric elastomer actuators (DEAs) is presented. The device consists of a fixed coplanar waveguide (CPW) and two metallic loading strips suspended on an elastomer membrane. The horizontal o ...

Novel Grid-Based Power Routing Scheme for Regular Controllable-Polarity FET Arrangements

Giovanni De Micheli, Pierre-Emmanuel Julien Marc Gaillardon, Odysseas Zografos

Polarity-controllable transistors have emerged in the last few years as an adequate successor of current CMOS FinFETs. Due to the additional polarity terminal, novel physical design techniques are required. We present a novel grid-based power routing schem ...

Understanding the Ageing Process, Recovering Phase and Fault Diagnosis of Electrochemical Double Layer Capacitors

Hubert Girault, Mario Paolone, Dimitri Torregrossa, Kathryn Ellen Toghill

This paper focuses on the description of the behavior of supercapacitors during over-temperature and over-voltage stresses and the consequent ageing processes. Specific physical evidences supporting the explanation of the experimental findings are provided ...

Effects of nearby buildings on lightning induced voltages on overhead power distribution lines

Mario Paolone, Carlo Alberto Nucci

For the case of urban overhead lines, the presence of nearby buildings is expected to affect the overvoltages induced by nearby cloud-to-ground lightning return strokes. So far, this effect has been seldom taken into account in the literature on the subjec ...

On the Validity of Approximate Formulas for the Evaluation of the Lightning Electromagnetic Fields in the Presence of a Lossy Ground

The accuracy of approximate formulas for the evaluation of lightning electromagnetic fields above and inside a lossy ground is investigated taking as reference full-wave numerical results obtained using a parallel implementation of the finite-difference ti ...

Application of the Matrix Pencil Method to Rational Fitting of Frequency-Domain Responses

Mario Paolone, Hamidreza Karami, Keyhan Sheshyekani

This paper presents a general methodology based on the matrix pencil method (MPM) for the fitting of frequency-domain responses in order to be properly represented in time-domain analysis. By virtue of the proposed method, a rational fitting of the frequen ...

Contribution to the Active Generator Principle

Antoine Béguin

This work is part of the innovative "Active Generator" (AG) project. AG is a concept that suggests a new arrangement of the turbine-generator line of a high power utility (a few hundred of MW) in order to de-synchronize the rotation speed of the turbine-ge ...

Deaging and Asymmetric Energy Landscapes in Electrically Biased Ferroelectrics

Dragan Damjanovic, Jun Chen

In ferroic materials, the dielectric, piezoelectric, magnetic, and elastic coefficients are significantly affected by the motion of domain walls. This motion can be described as the propagation of a wall across various types and strengths of pinning center ...

Synchronized Phasors Monitoring During the Islanding Maneuver of an Active Distribution Network

Mario Paolone, Carlo Alberto Nucci

The paper describes the performances of a phasor measurement unit (PMU) prototype based on a synchrophasor estimation algorithm conceived for the monitoring of active distribution networks, as well as its experimental application during some intentional is ...
