The Integration of contact heat measurement with intelligent fire fighter gloves assumes parametric simulations with the heat transfer module of COMSOL. A thermocouple is embedded into high temperature protective layers of the glove and measures contact heat. This is done by by pressing ... En savoir plus

We are developing nanoparticle detector for airborn particles. The detection principle is based on condensation of nanoparticles forming micron sized water droplets and detection of the droplets by a capacitive type nanodetector. We have successfully performed some experimental ... En savoir plus

Electronic Crystals are common forms of organization of charge in solids. They appear widely from nano-structure semiconductors to synthetic organic conductors. Charge density wave, the best treated kind of electronic crystal, can readjust its elementary units by creation of topological ... En savoir plus

An electromagnetic horn is a device used in particle physics to produce a strong pulsed toroidal magnetic field and to focus charged particles toward a detector. A multiphysics analysis is performed to assess the stress level inside the horn structure. In steady state regime, the horn ... En savoir plus

We apply COMSOL Multiphysics for reproducing our experimental observations of fluid flow and transport processes in geological media. Our experimental GeoEPT-method allows the 4D monitoring of transport processes in geological material on laboratory scale. Explicitly we import ... En savoir plus

This paper presents ongoing research aimed at development of a MEMS magnetometer capable of nanoTesla sensitivity. Such a device would pave the way for inertial-grade MEMS IMUs. A resonant sensor is proposed, based on a Xylophone Bar sense element, and is analysed both directly and via ... En savoir plus

Surface enhanced Raman scattering (SERS) investigations of silver and gold triangular nanoparticles reveal strong field enhancements at the corners of the particles. Though the measurements were done at wavelengths far from the surface-plasmon resonance of the particles, large field ... En savoir plus

In this paper we present an analysis that shows the Maxwell Fish Eye (MFE) only has super-resolution property for some particular frequencies (for other frequencies, the MFE behaves as conventional imaging lens). These frequencies are directly connected with the Schumann resonance ... En savoir plus

Evanescent-wave optical waveguide is widely used as sensing platform for chemical/biological sensor applications. Our research group contributed to on-chip IR sensor technology and made recent progress in miniaturizing such devices utilizing quantum cascade lasers (QCL) in combination ... En savoir plus

Nanoantennas – nanometer sized gold structures resonant at optical wavelengths have interesting properties for many applications. For numerical simulations of such structures simplified geometries are usually considered. However the fabricated shapes still differ significantly from ... En savoir plus
