Robust mass lumping and outlier removal strategies in isogeometric analysis
Annalisa Buffa, Espen Sande, Yannis Dirk Voet
Mass lumping techniques are commonly employed in explicit time integration schemes for problems in structural dynamics and both avoid solving costly linear systems with the consistent mass matrix and increase the critical time step. In isogeometric analysi ...
2024Spin wave dispersion of ultra-low damping hematite (α-Fe2O3) at GHz frequencies
Dirk Grundler, Mohammad Hamdi, Ferdinand Rémy Hynek Posva
Raw data associated to the manuscript ‘’Spin wave dispersion of ultra-low damping hematite (α-Fe2O3) at GHz frequencies‘’, Physical Review Materials 7, 054407(2023); doi: 10.1103/PhysRevMaterials.7.054407 Information about file fo ...
Zenodo2023Spin wave dispersion of ultra-low damping hematite ( α−Fe2O3 ) at GHz frequencies
Dirk Grundler, Mohammad Hamdi, Ferdinand Rémy Hynek Posva
Low magnetic damping and high group velocity of spin waves (SWs) or magnons are two crucial parameters for functional magnonic devices. Magnonics research on signal processing and wave-based computation at GHz frequencies focused on the artificial ferrimag ...
2023Dataset for "Biodegradable materials as sensitive coatings for humidity sensing in S-band microwave frequencies"
Danick Briand, Nicolas Francis Fumeaux, James Alec Pierce Bourely, Leticia de Sousa, Oleksandr Vorobyov
This dataset contains the data collected during the SNSF BRIDGE GREENsPACK project (Grant no. 40B2-0_187223) in association with the recent publication entitled “Biodegradable materials as sensitive coatings for humidity sensing in S-band microwave frequen ...
EPFL Infoscience2023Deriving Major Ion Concentrations at High Resolution from Continuous Electrical Conductivity Measurements in Karst Systems
Time series of hydrochemical parameters support the investigation of dominant karst hydrological processes and conceptual model structures. Nevertheless, high costs for sample collection and analyses cause hydrochemical data to be rarely available at a suf ...
SPRINGER INTERNATIONAL PUBLISHING AG2023Cavity-Mediated Coupling of Terahertz Antiferromagnetic Resonators
Jean-Philippe Ansermet, Marcin Bialek
Coupling of space-separated resonators is interesting for quantum and communication technologies. In this work, we show that antiferromagnetic resonance in separated parallel-plane slabs of hematite (alpha-Fe2O3) couple cooperatively to terahertz electroma ...
AMER PHYSICAL SOC2023Biodegradable materials as sensitive coatings for humidity sensing in S-band microwave frequencies
Danick Briand, Nicolas Francis Fumeaux, James Alec Pierce Bourely, Leticia de Sousa, Oleksandr Vorobyov
Worldwide, electronic waste represents the fastest-growing stream of waste. With an increasing number of connected devices, passive and eco-friendly environmental sensing solutions need to be developed. Wireless passive devices for RFID and sensing exist, ...
2023Ultrahigh Electrostrictive Effect in Lead-Free Ferroelectric Ceramics Via Texture Engineering
Dragan Damjanovic, Li Jin, Yuan Sun
The electrostrictive effect, which induces strain in ferroelectric ceramics, offers distinct advantages over its piezoelectric counterpart for high-precision actuator applications, including anhysteretic behavior even at high frequencies, rapid reaction ti ...
Washington2023Broadband spectroscopy and inelastic light scattering on the canted antiferromagnet hematite for antiferromagnetic magnonics
Collective spin excitations propagating in magnetically ordered materials are called spin waves (SWs) or magnons. They are promising for low-power and beyond-CMOS information processing, which do not suffer from the ohmic losses. SWs in ferromagnets (antif ...
EPFL2023Lightning interaction with the ionosphere
Marcos Rubinstein, Dongshuai Li
Lightning discharges, including cloud-to-ground (CG) and intracloud (IC) lightning, are known to emit electromagnetic pulses (EMPs) in a wide frequency band ranging from few Hz up to hundreds MHz [1]. During the breakdown and ionization processes (mostly f ...
