We present an easy-to-use toolbox for the automated generation of reduced-order mixed-level models for the evaluation of squeeze-film damping in microelectromechanical systems. The toolbox is programmed in JAVA and heavily exploits the functionality provided by the COMSOL API. The ... En savoir plus

Coil antenna is the simplest form in well-logging tools for resistivity measurement of the formation. This paper introduces how to accurately compute the impedance of the coil with very thin wires at high frequency, and with the complex borehole structure, e.g., metal housing and ... En savoir plus

Introduction: Accurate fluid temperature control in microfluidic channels is a requirement for many lab-on-chip and micro-reactors.Thin films resistive metal heaters have proven to be the best choice for localizing heating applications with integrated microfluidic systems. A thin ... En savoir plus

The study of plasmonic structures continues to be at the forefront of research in nanotechnology and condensed matter physics. Here, we present a numerical model we have created and verified to characterize the frequency dependence of the effective magnetic permeability and permittivity ... En savoir plus

In this work, the numerical simulation of Mexican softwood (Pinus pesudostrobus) drying is presented by solving a physics-based model. The model was developed by considering the heat and mass transport and the representative elementary volume, which involves the solid, liquid and gas ... En savoir plus

Cochlear Implants are implantable devices which bypasses the non-functional inner ear and directly stimulates the hearing nerve with electric currents thus enabling deaf people to experience sound again. Implant electrode array design is limited in electrode count, due to their large ... En savoir plus

Propagation models for avalanche rescue systems are studied here. The paper focuses on the through-the-snow electric field propagation at ISM frequencies, comparing several models (air model, snow model, three-layered model) and using different solving method (geometrical optics, ...

In this paper, we use COMSOL, finite element software, to compute the magnetodielectric effect in a multiferroic structure based on a {ferromagnetic /piezoelectric} multi-layer. We also investigate the potential tunable applications of such structures at microwave frequencies. In a first ... En savoir plus

In the presented work the dynamic simulation of a silicon anodization process is performed. Two mechanisms of etch form development (diffusion in electrolyte, current flow) are considered and simulated. Influence of electrolyte conductivity and radius of the opening in the masking layer ...

A one-dimensional model of Excimer Laser-Annealing of amorphous silicon layers which are irradiated with a KrF excimer laser is described. For realisation, the application mode heat transfer in solids is used. The model predicts a melt threshold for the energy density of the laser of 88 ... En savoir plus
