Lightning Localization Using Three-Dimensional Time Reversal MUltiple SIgnal Classification (TR-MUSIC) Algorithm
Marcos Rubinstein, Hamidreza Karami
In this paper a three-dimensional (3D) Time Reversal MUltiple SIgnal Classification (TR-MUSIC) algorithm is proposed to localize lightning discharges. The performance of the proposed algorithm was evaluated considering different scenarios and taking into a ...
2023Secondary Fast Breakdown in Narrow Bipolar Events
Marcos Rubinstein, Dongshuai Li
The physical mechanism of Narrow bipolar events (NBEs) has been studied for decades but it still holds many mysteries. Recent observations indicate that the fast breakdown discharges that produce NBEs sometimes contain a secondary fast breakdown that propa ...
2022Dielectric properties of 3-3 flexible composites by infiltration of elastomers into porous ceramic structures using cellulose scaffold
Elastomer composites are prepared by infiltrating polydimethylsiloxane (PDMS) into a porous ceramic structure of nanoparticles. This method differs from the conventional approach, where particles are dispersed into the polymer matrix, since here, the polym ...
PERGAMON-ELSEVIER SCIENCE LTD2022The Geometry and Charge of the Streamer Bursts Generated by Lightning Rods under the Influence of High Electric Fields
The streamer bursts generated during the initiation and propagation of leaders play an important role in the creation and maintenance of hot discharge channels in air. The most important parameters related to streamer bursts in this respect are the length ...
2022Optimized electrochemical breakdown etching using temporal voltage variation for formation of nanopores in a silicon membrane
Dielectric breakdown etching is a well-known method of making nanopores on thin (similar to 50 nm) dielectric membranes. However, voltage driven translocation of biomolecules through such nanopores becomes extremely fast. For improved detection, for instan ...
ELSEVIER SCIENCE SA2021Evaluation of dielectric elastomers to develop materials suitable for actuation
Yves Perriard, Yoan René Cyrille Civet, Thomas Guillaume Martinez, Jonathan André Jean-Marie Chavanne, Morgan Almanza
Electroactive polymers based on dielectric elastomers are stretchable and compressible capacitors that can act as transducers between electrical and mechanical energies. Depending on the targeted application, soft actuators, sensors or mechanical-energy ha ...
2021Stretchable and Soft Electroadhesion Using Liquid‐Metal Subsurface Microelectrodes
Dario Floreano, Yegor Piskarev, Jun Shintake, Michael Dickey
Electroadhesion is an attractive mechanism to electrically modulate adhesion to surfaces. Electroadhesion arises from the interaction of electric fields with conductive or dielectric materials. Electroadhesion devices consist of in-plane, interdigitated el ...
2021Fluctuation relations for systems in a constant magnetic field
Sara Bonella, Alessandro Coretti
The validity of the fluctuation relations (FRs) for systems in a constant magnetic field is investigated. Recently introduced time-reversal symmetries that hold in the presence of static electric and magnetic fields and of deterministic thermostats are use ...
2020Double-gate field-effect-transistor based biosensor
The present invention concerns a biosensor (1) comprising: a source element (13); a drain element (17); a semiconductor channel element between the source element (13) and the drain element (17) for forming an electrically conductive channel with adjustabl ...
2019Two Possible Scenarios for the Formation of Category 1 Bipolar Lightning Flashes
Marcos Rubinstein, Mohammad Azadifar, Davide Pavanello, Qi Li
We present and discuss the current and electric field waveforms associated with two upward bipolar lightning flashes that occurred at the Säntis Tower. According to the traditional classification of bipolar flashes, both observed flashes could be classifie ...
